Abstract :
In this paper, we consider a novel forwarding technique based on geographical location of the nodes involved and random selection of the relaying node via contention among receivers. A new collision avoidance scheme based on this idea is described in detail, and an approximate analysis is provided. The proposed scheme is compared with a similar solution based on busy tones, as well as with STEM, and is shown to perform well for sufficient node density. Compared to a previously proposed protocol, the one presented here only needs one radio, thereby greatly simplifying the hardware.
