Abstract

Research on performance optimization of the physical layer of communication networks has been focused on the development of transmission techniques such as MIMO and OFDM/DMT that effectively exploit the space and frequency dimension. However, the physical layer is usually configured statically and thus fails to properly exploit the time dimension. Upper layers in the protocol stack hold crucial information on the time dependent nature of the network traffic, which can indeed be exploited by the physical layer to dynamically select different configurations and increase overall network efficiency. Therefore, the aim of this project is to develop real-time adaptive physical layer control algrithms that can be combined with existing upper layer network functions so as to additionally exploit the time dimension optimally. The possibilities and performance gains of real-time adaptive physical layer control will be explored in the context of fifth generation broadband copper access networks (5GBB). 5GBB envisages a hybrid fiber-DSL deployment where the fiber network is terminated near the boundary between public and private property. In such deployment, the reduced copper loop length, together with the use of specific (e.g. full duplex) transmission techniques, enables data rates of up to 10 Gbps. In addition, the specificity of the deployment scenario is to make, for the first time, the implementation of real-time adaptive physical layer control algorithms a feasible objective.

Abstract

Cities are relying on Internet of Things (IoT) to make their infrastructure smart by using advanced sensing and control devices within the city's infrastructure with the goal of improving urban living, city's experience, etc. Analysis of the data generated by a wide range of sensors and actuators allows controlling the city in a better and more automated way, with respect to e.g. the view on the city's mobility patterns. To realize a smart city infrastructure we consider three layers: the network/sensor layer, i.e. a city-wide network based on a variety of communication technologies and its protocol stacks together with a variety of sensors allowing the collection of raw data; a data layer, dealing with the continuous stream of data and its techniques for processing, storing, mining; an application layer, responsible for interpreting the processed data stream for more optimally controlling the city. The network/sensor layer will be covered by the MOSAIC research group (Dept. Mathematics and Computer Science, Chris Blondia and Steven Latré), while the data layer will be dealt with by the ADREM research group (Dept. Mathematics and Computer Science, Bart Goethals) and finally the application layer is the responsibility of the Transport and Regional Economics research group (Dept. Transport and Regional Economics, Eddy Van de Voorde and Thierry Vaneslander). The general aim of this project is to bring together the expertise present at the University of Antwerp at each of these layers, in order to bundle the research and come up – through an intensive collaboration - with a framework covering the three layers. More specifically, we will build an integrated smart city platform, tailored towards mobility, that allows to capture, process, analyze, interpret and control smart city data in general and mobility data particularly. As discussed in the next section, this will result in important novel research contributions in each of the three layers and will result in a proof-of-concept where the research results are combined into a demonstrator.

Abstract

As everyday devices are being connected to the Internet, research on large-scale wireless sensors networks specifically and Internet of Things (IoT) generally are becoming more and more important. There is a considerable research and innovation effort related to the deployment of smart cities using this IoT technology. However, there are still plenty of hurdles to move from R&D to implementation and real mass-scale deployment of wireless sensors networks. Moreover, the city itself is a treasure of data to be explored if the right sensors can be installed. Testbeds are the preferred tools for academic and industrial researchers to evaluate their research but a large-scale multi-technology smart city research infrastructure is currently the missing link. The City of Things research infrastructure will build a multi-technology and multi-level testbed in the city of Antwerp. As a result, 100 locations around the city of Antwerp and its harbour will be equipped with gateways supporting multiple wireless IoT protocols. These gateways will connect with hundreds of wireless sensors and actuators, measuring smart city parameters such as traffic flows, noise, air pollution, etc.

Abstract

Traditional social organizations such as those for the management of healthcare are the result of designs that matched well with an operational context considerably different from the one we are experiencing today. The new context reveals all the fragility of our societies. Main aim of SELFSERV project is to complement the "old recipes" with smarter forms of social organization based on the self-service paradigm and by exploring culture-specific aspects and technological challenges. The SELFSERV project's primary objective is to design a platform addressing the needs of the Moroccan diabetic patients and hooking into the selfserving "wells" of the Moroccan societies and culture.

Abstract

Optimal operation of sensor networks takes on a fundamentally different nature when energy harvesting is a primary or even secondary means of power supply due to the following reasons: (1) the topology of active nodes may change more drastically due to intermittency in the energy supply. This necessitates an even greater focus on resilience and self-organization in the control and performance of such networks; (2) the unpredictable nature of energy supply represents not only a challenge but also an opportunity: not only is it important to be frugal when energy supply is low, good controls for such networks should also make good use of periods or regions with high energy supply. Therefore, our objectives are to assess how these differences affect the performance of such networks by mathematical models, and also, inspired and informed by these models, to propose new control principles for such networks.

Abstract

Bringing the images from camera to TV screen is a complex production process involving several actors in the media sector. As currently no decent technological solution is available to connect geographically spread locations, many media actors are located close to each other, in order to allow efficient collaboration. The MECaNO project addresses these limitations by developing a network technology enabling decentralised collaboration, just-in-time workflows and guaranteed performance. As such, MECaNO will deliver both a technological and techno-economic optimal solution for the media sector, and evaluate it on realistic use-cases.

Abstract

Community networks are an emerging and successful model for the Future Internet across Europe and far beyond.The CONFINE project complements existing FIRE infrastructure by establishing a new facility built on the federation of existing community IP networks constituted by more than 20,000 nodes and 20,000 Km of links. These community networks incorporate a large and wide variety of commodity wireless and optical links, heterogeneous nodes, different routing protocols, applications and a large number of end-users, following an innovative model of self-provisioning using unlicensed and public spectrum.The project develops a unified access to an open testbed with tools that allow researchers to deploy, run, monitor and experiment with services, protocols and applications on real-world community IP networks. This integrated platform will provide user-friendly access to these emerging networks supporting any stakeholder interested in developing and testing experimental technologies for open and interoperable network infrastructures, strengthening open community networks. This type of networks is an emerging and successful model for the Future Internet across Europe and beyond. The project includes as partners well established community networks with large end-user bases and diverse application providers (e.g. content distribution, voice, data and multimedia communication), research institutions with experience in key related areas, non-profit organizations and SMEs with experience in supporting researchers, community networks and end-users.

Abstract

Because of the strong increase of advanced multimedia applications requiring high bit rates, the capacity of the current wireless networks becomes insufficient. Further, the increase of the mobility in time-variable radio channels and the higher bit rates cause an increasing frequency selectivity, such that the transmitted signals are distorted, and disturbed by interference and noise. It is therefore of great importance to investigate new techniques to increase the capacity (in terms of more users and higher bit rates) and to improve the performance for the transmission over these radio channels.In this project proposal, the expertise of the different research groups will be brought together in order to obtain research results that lead to an increase of the capacity of future wireless networks.

Abstract

Wireless technology is a key driver in adding value in building automation through the deployment of technology. Indeed, installing and commissioning a myriad of wired networks has been reported to be a major source of effort and thus of cost. The multitude of wired networks in a typical professional building consists of the computer network, the fire alarm network, the emergency lighting network, the access control network, etc. Recently the different networks are being deployed using a building automation bus system such as EIB, LON and BACNET. Where the interoperability issues for these wired networks are gradually being solved, fundamental technological problems remain when deploying these services over wireless networks. These challenges need to be met simultaneously, adding extra complexity to the task. The innovation objective of this project is to tackle each challenge both individually and as a component of the full framework. The resulting wireless architectures, algorithms and technique will the form an example of cutting edge scientific results on how to deploy wireless building automation. As buildings are a harsh environment for wireless signals, a key element in the project is to build and evaluate a Proof-of-Concept.

Abstract

Recent developments in intelligent sensors, such as (bio) medic sensors, in combination with the steady evolution in wireless networks, in particular ad hoc networks, pave the way for a new type of networks, Body Area Networks or BAN's. A BAN is a network in which, several compact mobile devices, attached to the body, communicate using a wireless network. Interaction with the user will be possible using a central intelligent device (e.g. a PDA). We distinguish two types of devices: sensors and actuators. Sensors will be used to measure certain parameters. Some examples of sensors are: external medical sensors (monitor the heartbeat, blood pressure, body temperature, recording a long term ECG ...), internal or implanted medical sensors (measuring of the cerebral activity for epileptic patients, measuring the glucose levels in the blood of diabetics, endoscopy where the sensor is built into a pill, retina prostheses for the visually impaired existing of a matrix of micro sensors that transform electrical signals into neurological signals and thus mimic the normal behaviour of the retina ...), microphone, headphone, digital glasses with the functionality of a PC monitor, ... The second category of devices is called actuators that will act in function of the measured parameters in the sensors or by interaction with the user. Some possibilities for actuators are: a device for administering the correct dose of insulin to diabetics, based on the measures glucose level, intravenous administering of medication when a higher cerebral activity is detected and thus preventing an epileptic seizure, changing the image of the digital glasses, ... Thanks to a BAN, in the future it will be possible to monitor patients continuously and to apply the necessary medication, whether it is in a hospital or at home or during transportation. Patients will no longer need to keep to their beds, but will be able to move about freely. Elderly people will be able to live in their own home longer and will not need to move to a retirement home or at least not until a later age. Training schedules of professional athletes can be monitored more closely.

Abstract

The main purpose of this project is to set up several new queueing models as well as developing efficient computational methods that allow us to determine the most significant performance measures (for instance, the waiting time distribution or the number of users that can share a resource without violating the agreement between the end users and the network provider). The choice of these models is driven by the latest developments in the telecommunication field. For a limited number of models we already obtained some preliminary results during the current FWO postdoc fellowship. The emphasis of the ongoing project lies mostly on applying existing models to broadband access networks, while the development of new models is of lesser importance. It is thus fair to state that the scope of this project proposal is somewhat more general.

Different existing routing algorithms will be compared with special attention for throughput scalability and the speed of the setup of new connections. This will happen with the focus on the application of ad hoc networks in disaster scenarios. Apart from the comparison of existing routing algorithms research will be done on new routing algorithms that not only enhance the throughput, scalability and speed of connection setup, but can also guarantee quality of service for e.g. videostreams.

Abstract

The project is focusing on the development of novel and generic technologies for the support of the mobile multimedia network of the future. The network should support the mobility (interdomain, intradomain and within an access network) and should provide end-to-end QoS with different characteristics (depending on the service, terminal, access and wireless link technology) and in a point-to-point or point-to-multipoint mode (multicast).

Abstract

One of the key technological challenges to advance our knowledge-based society is the development of mobile multimedia communication systems and networks. Some general trends we observe today are : the increasing importance of multimedia services, the unprecedented growth of mobile telephony, the increasing importance of the Internet protocol as the integrating network technology, the importance of wireless access to the network, the increasing diversity of terminals. It is interesting to observe that the push towards wireless networks, the diversity in terminals and services, and the requirement for QoS and mobility, results in a situation where services should be matched to physical layer aspects (and of course with the networks and systems in between). The IAP/PAI consortium has bundled the expertise at the different levels required for the development of future mobile multimedia communication systems and networks. As a result, the project has been structured in a natural top-down approach, starting from the applications and ending with physical layer aspects. The interaction between these different fields of expertise will form a strong basis for the success of the project. The project is structured as follows : WPl : Applications WP2 : Network Design WP3 : Traffic and Performance Modelling WP4 : Modulation, Channel Coding and Propagation The major goals of the project can be summarized as follows : .Development of a software architecture for the use of dynamic metadata for the support of multimedia applications in a mobile environment. .The development ofhighly-scalable, object-based video coding schemes. .To develop new terminal concepts taking into account the format in which the data are transported between the multimedia source and a portable terminal. .To design and evaluate new protocols that allow seamless hand-offs and support end-to-end QoS for mobile terminals/services in homogeneous and heterogeneous network environments (including multicast support and the use of active networking). .To study generic queueing models which deal with connection and handover blocking probability in a wireless environment. To develop a generic stochastic model for the evaluation of macro- and micro- mobility solutions on the network layer . .To develop next generation QoS-enabled mobile ad hoc networks supporting heterogeneous and fast moving terminals based on active networking technology .To develop advanced routing algorithms and model contention resolution and reservation schemes. .To model web-type applications and to develop traffic models including characteristics related to mobility . .To study the performance of appropriate error detection and retransmission techniques (ARQ protocols) in a mobile and wireless environment (including TCP enhancements). .Design of receiver algorithms (synchronization, equalization, detection) for advanced modulation and transmission techniques- .The exploitation of multiple transmit and receive antennas and so-called smart antenna principles to enhance capacity and performance, and applying space-time coding to such multiple-input multiple- output systems- .The development of iterative (turbo) processing in multiuser detection, interference suppression, parameter estimation and error correction. Design of advanced compact antennas and free space electromagnetic wave propagation models for high bandwidth short distance wireless communications.

Abstract

The project goal is to contribute to the development of next generation transport networks using optical technologies. The focus will be on the networking aspects. It is envisaged that IP will be the convergence layer of future multimedia traffic, including the classical IP based data traffic and the classical telephony traffic. A clear understanding of optical circuit switched networks will be obtained. Major results will be obtained in the field op control architecture and routing strategies (for different network architectures). Resilience strategies will be developed and evaluated in great detail. A better understanding of optical packet switched networks will be obtained. Major emphasis will be on the node architectures. The partners are confident that it will be possible to analyse the specific queueing models necessary to evaluate the performance of optical packet switched networks by extending the techniques already developed in the past for other types of communication networks. Also a comparison between packet and circuit switched optical networks will be performed. A planning approach will be developed to support operators and vendors in strategic decisions concerning future network architectural options.

Abstract

The aim of this research is to investigate the MAC layer for Ethernet Passive Optical Networks (EPON). In the past few years, a lot of attention has been paid to ATM Passive Optical Networks. Recently, research has started on potential successors of the APON, namely solutions that are not necessarily ATM based and that allow variable packets. A first initiative in this context is the EFM (Ethernet in the First Mile) forum. The proposed research will be done from a performance point of view, and therefore, modeling and performance evaluation will be major activities.

Abstract

The objective of this project is to evaluate the performance of random access algorithms. Such algorithms are deployed in the current and next generation access networks, e.g., HFC networks, to allow for end users to reserve uplink bandwidth. Both a theoretical as well as a practical approach is used. Moreover, we also aim at further developing the theoretical tools, such as queuing theory and stochastic processes, often used within such a context.

Abstract

This project will analyze the performance of advanced technological systems such as communication networks (including the Internet), computer systems, and distributed multiprocessor systems, with the aim of optimizing their design and dimensions. This analysis will use probabilistic models, the parameters of which will be obtained by statistical estimates based on measurements of actual traffic. The computation of the performance functions and the design of optimal networks both lead to complex computational problems, which will be approached by si mulation and by novel numerical analysis techniques such as multivariate rational approximations. The many interactions between all these aspects require an intensive collaboration between the three research groups.

Abstract

Starting from observed data (like traffic on the Internet), robust statistical methods (i.e., techniques that give reliable results even when deviations occur in the input data) will be applied to construct a model for the observed system. From the specific architecture and structure of the system one can often derive interesting properties of the performance measure in advance, such as its monotonicity relative to a given system parameter, or its asymptotic behavior. These properties are helpful when constructing the performance measure, but by themselves they are not sufficient. Robust, efficient and accurate approximations of the exact solution are indispensable. A possible approach is based on power series, but since many performance functions have singularities a better approach is to use Pade approximations.

Abstract

The analysis and performance evaluation of advanced technical systems, such as computer systems, telecommunication systems and distributed multiprocessor systems often involve solving a complex computational problem. This is due to the fact that the complexity increases with the size of the system under study or with the dimensions of the system model. This implies that it is preferable to use rational functions rather than polynomials.

Abstract

The goal of this project is to develop basic technologies for the next generation multiservice networks. These basic technologies include new algorithms (e.g. routing and planning), protocols (e.g. Medium Access Control), methods (e.g. buffer dimensioning, traffic management) and architectures (e.g. network and service management). The following question will be answered: how can QoS be supported in an IP network, how do IP and ATM based networks interwork, hoe to provide in a cost effective way bandwidth in a backbone and access network, taking into account the uncertain demand and cost evolutions, how will the management be done of the networks and services.

Abstract

The main aim of the project is the integration of operational issues into the design process of object oriented systems. To master the growing complexity of current computer, communication and information systems, one divides these systems into small functional entities which are more or less independent of each other. The object-oriented paradigm supports this modular view. A first objective of the project is to develop a formalism that is sufficiently universal to bridge the structural differences between the various modules and subsystems. A second objective is to improve the interoperatability of object oriented information systems, by investigating properties and structure of the interfaces between system components. A further objective is the analysis of configurations of complex systems. One way to tackle this problem is to reduce it to that of finding an eigenvector of a large matrix.
