Perimeter Surveillance, RF Tomography, and Compressive Sensing                 

Himed Braham,  Air Force Research Lab, USA

 

Abstract

Several recent events have generated a renewed interest in dual‐use applications of military technology. Most notable among these technologies being applied to homeland security and law enforcement are sensors and information systems with potential to automate perimeter surveillance, building intrusion, and transportation infrastructure monitoring. The key to the successful implementation of unmanned sensor technology for the applications listed above is modular systems with common algorithms, processing architectures, and scalability. The sensor aperture size is dictated by surveillance coverage requirements on range, height, and angle, and poses the major challenge to the design and deployment of scalable modular systems. Within this contest, sensor fusion offers the most cost effective and timely solution to the scalability problem. As such, signal processing is the critical technology discussed in this presentation. This includes data conditioning, reformatting, transformation to the appropriate domain, integration to form a comprehensive assessment of the surveillance volume, and display for appropriate action to be taken. In this talk, we extend the concept of RF tomography to the perimeter surveillance problem. In this context, image formation using a tomographic structure is considered and new concepts such as compressive sensing are discussed, especially in cases where sparsity is an issue.

Mobile Flexible Networks:  Breaking The Spectral Efficiency Barrier

Merouane Debbah, Supelec, France


Abstract:

The general term "small cell networks" covers a range of radio  network design concepts which are all based on the idea of deploying  base stations much smaller than typical macro cell devices in order to offer public or open access to mobile terminals. The main benefits are:
1) to allow offloading the traffic from the macro cell and provide dedicated capacity to urban hotspots.
2) to allow for unprecedented mobile system capacities (in terms of Gbit/s/km2).

3) to have the potential to reduce the ecological footprint of cellular  networks by bringing mobiles and base stations closer together.

4) to make cell site rental and dedicated backhaul provisioning  superfluous since they rely on existing backhaul infrastructure.

Finally, self-organization and optimization of the devices allows for plug and play deployment, requires no network planning and reduces maintenance costs. We will discuss the challenges ahead and some research directions that develop the theoretical and practical foundations of these networks.

On the Robust & Secure Transmission of Information Over Wireless Cooperative Networks

Jean Yves Chouinard, LRTS, Laval Uni., Canada

 

Abstract:

Recent advances in communication theory and technologies has led to the definition of fixed and mobile wireless cooperative networks. New high rate wireless infrastructures have been defined such as 4th generation standards such as WiMAX and LTE. However, deployment of such networks represents new design challenges for network operators and equipment manufacturers. For instance, due to the increasing geographical density of users, high mutual interference levels impose severe limitations to the achievable data rates, thus affecting the distribution of multimedia information.

In this plenary talk, we will introduce wireless cooperative networks and their inherent limitations. Methods to ensure efficient, robust and secure transmissions over wireless networks will be addressed.

The propagation behaviour of signals over frequency selective fading channels will first be exposed. The wireless cooperative networks capacity is an important factor in the investigation of the best cooperative strategies among a network’s nodes, or relays. Then network cooperative diversity in real-life imperfect wireless channels will be addressed. Effective diversity depends on the actual correlation between the different signals received by multiple antennas (virtual multiple antenna system). Finally, security in wireless cooperative networks will be discussed. Methods to ensure protection against different attacks over wireless networks will be presented in the context of highly vulnerable wireless network links.

Signal Processing For Security And Encryption

Said Boussakta, Newcastle Uni., UK

 Abstract

The introduction of computer networks and the widespread use of the internet, coupled with significant advances in communications technology, have made it possible to trade, exchange and access information or send messages from the office or home to most places in the world. As the variety of data exchanged across a network has increased drastically over the last few years, so the threat of its interception during transmission or storage set an alarm and nowadays it has become a major concern. Algorithms and solutions which help prevent interception and enhance data security during transmission or storage are now of primary importance. Over the years signal processing has been indispensible for solving different problems in science and technology. The outcome of the work carried out in this field over the last few decades has been impressive, resulting in a broad range of efficient algorithms. In fact, new signal processing techniques are continuously emerging to solve many new or open problems created by technological advances or the demand of new applications and challenges such as modern data encryption and security.

Therefore the aim of this talk is to introduce some recent research and developments of signal processing in modern encryption and security algorithms for data transmission and storage.
