Impact of multipath fading in wireless ad hoc networks
This paper examines several MANET behaviors and suggests root causes using a stochastic model of received power. It focuses specifically on MANET mechanisms most impacted by fine-grain variations in signal strength. Specifically, it examines 1) the impact of MAC retries on performance, 2) a possible cause of excessive route persistence, 3) route stability in MANETs, and 4) difficulties in estimating the mean SNIR in a MANET. It does so through mathematical analysis, simulation and comparisons to published field results.
