Résumé:

In this talk, we describe a novel forwarding technique based on geographical location of the nodes involved and random selection of the relaying node via contention among receivers. We first provide a description of the basic idea and study the multihop performance of the scheme. We then provide a detailed description of a MAC scheme based on these concepts and on collision avoidance, and report on its energy and latency performance. Using analysis and simulation, we show that the proposed technique is able to achieve significantly better performance than current schemes in some useful scenarios. Extension to more general metrics is also discussed.
