Abstract

This paper aims at improving the power efficiency of the CSMA/CA protocol for transmission of multimedia information over multihop wireless channels. Using a distance dependent propagation model, we present a power control scheme, which is based on the receiver sensitivity adjustment mechanism. The receiver sensitivity approach aims at exploiting a tradeoff between the interference and the contention in accessing the shared medium. For real-time traffic, we show that by controlling the receiver sensitivity threshold we can significantly improve the multihop link performance
