With the price of wireless sensor technologies diminishing rapidly we can expect large numbers of autonomous sensor networks being deployed in the near future. These sensor networks will typically not remain isolated but the need of interconnecting them on ...
Although much research has been devoted to designing and experimenting on ad hoc networks of tiny devices, very little has focussed on devising theoretical models to capture the inherent power and limitations of such networks. A notable exception is the po ...
We study the scaling of the broadcast capacity for a network with a single source and f(N) cooperative relays where N is the number of destinations and f(.) is an increasing function. We consider random extended networks (the network area goes to infinity ...

Wireless networks suffer from a variety of unique problems such as low throughput, dead spots, and inadequate support for mobility. However, their characteristics such as the broadcast nature of the medium, spatial diversity, and significant data redundanc ...
Effective communication mechanisms are a key requirement for schools of submersible robots and their meaningful deployment. Large schools of identical submersibles require a fully distributed communication system which scales well and optimises for ”many-t ...
The privacy of users of mobile devices has been at stake, with emerging systems based on the mobile ad hoc networking technology raising additional concerns. The establishment of a connection between two nodes could readily reveal information to an eavesdr ...
We use a decision-support system for agriculture based on a wireless sensor network, in order to understand how scientists solve a typical problem that requires environmental data (such as soil moisture, temperature, etc.). Subjects use an existing interfa ...
n source and destination pairs randomly located in an area extending linearly with n want to communicate with each other. Signals transmitted from one user to another at distance r apart are subject to a power attenuation of r^{-alpha} and random phase cha ...
The recent advances made in MEMS and particularly in RF MEMS technology are enabling new architectures for the integration of RF transceivers with improved performance and smaller size. Several fundamental building blocks benefit from the availability of h ...
Vehicular Networks (VNs) are emerging, among civilian applications, as a convincing instantiation of the mobile networking technology. However, security is a critical factor and a significant challenge to be met. Misbehaving or faulty network nodes have to ...
