Although many energy efficient/conserving routing protocols have been proposed for wireless sensor networks, the concentration of data traffic towards a small number of base stations remains a major threat to the network lifetime. The main reason is that t ...
The analysis and design of routing algorithms for finite buffer networks requires solving the associated queue network problem which is known to be hard. We propose alternative and more accurate approximation models to the usual Jackson’s Theorem that give ...
Several misbehavior detection and reputation systems have been proposed for mobile ad-hoc networks, relying on direct network observation mechanisms, so-called watchdogs. While these approaches have so far only been evaluated in simulations and restricted ...
Ultra-Wide Band (UWB) is an emerging wireless physical layer technology that uses a very large bandwidth. We are interested in finding the design objectives of the medium access (MAC, namely, power control and scheduling) and routing protocols of a multi-h ...
We present the first polylog-competitive online algorithm for the general multicast admission control and routing problem in the throughput model. The ratio of the number of requests accepted by the optimum offline algorithm to the expected number of reque ...

We introduce autonomous gossiping (A/G), a new genre epidemic algorithm for selective dissemination of information in contrast to previous usage of epidemic algorithms which flood the whole network. A/G is a paradigm which suits well in a mobile ad-hoc net ...
In this paper, we address the problem of dynamic protocol update (DPU) that requires global coordination of local code replacements. We propose a novel approach to DPU. The key idea is the use of synchronization facilities of the services that get updated. ...

It is appealing to implement publish/subscribe systems in a peer to peer (P2P) manner to circumvent the scalability issues of broker-based (semi-decentralized) systems and simplify the deployment. While existing P2P generic infrastructures provide a scalab ...
