Back to the basics: Neighborhood discovery in mobile ad hoc networks
In ad-hoc networks, most of protocols are based on knowledge of the so-called neighbors of the nodes. The neighborhood of a given node is the set of stations that can communicate with this node. The discovery of these neighbors is currently based of a "HELLO protocol" which sends a beacon at a given period. In this presentation, we will discuss about optimization of this family of protocols in order to obtain accurate neighborhood while minimizing energy consumption. In particular, we will study solutions where the frequency of the beacons is dynamically adapted to the topology of the network.

He was nominated as a member of the Institut Universitaire de France (IUF) in 2009 and was head of the Inria Pops project-team from 2004 to 2011. His research interests include sensor and mobile ad hoc networks, mobile and distributed computing, smart objects, and RFID technologies. He is involved in numerous international conferences (MASS 2010-2011, INFOCOM 2011-2014), and editorial activities (associate editor of TPDS and COMNET).
