In wireless systems, neighbor discovery (ND) is a fundamental building block: determining which devices are within direct radio communication is an enabler for networking protocols and a wide range of applications. To thwart abuse of ND and the resultant c ...
The term distributed Consensus denotes the problem of getting a certain number of processes, that could be far away from each other and that exchange messages through some communication means, to all agree on the same value. This problem has been proved im ...
In this paper, we study dynamic protocol update (DPU). Contrary to local code updates on-the-fly, DPU requires global coordination of local code replacements. We propose a novel solution to DPU. The key idea is to add a level of indirection between the ser ...

In this paper we study dynamic protocol updates (DPU), which consist in replacing, without interruption, a given protocol during execution. We focus especially on group communication protocols. The paper proposes a methodology to conveniently describe whic ...
Nowadays, advances in telecommunication network design and performance analysis often rely on dedicated software tools. Unfortunately, developing new tools is a very time and resources consuming activity. To rationalise development costs, existing applicat ...
We consider a source that transmits to a receiver by routing the information packets over a communication network and examine rate benefits that finite complexity processing at the intermediate nodes may offer. We show that the processing capabilities of t ...
Modern communication networks are reaching a high level of complexity. As their global dimensioning and performance evaluation are very hard tasks, a multi-layer approach is generally applied to divide them in smaller problems easier to tackle. Within this ...
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. ...
If a network is to operate successfully, its users need to collaborate. Collaboration takes the form of following a network protocol and involves some resource expenditure on the part of the user. Therefore, users cannot automatically be expected to follow ...
