Power Control in Multihop CSMA

This paper aims at improving the power efficiency of the CSMA/CA protocol for transmission of multimedia information over multi-hop wireless channels. Using a distance dependent propagation model, the authors 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, they show that by controlling the receiver sensitivity threshold they can significantly improve the multi-hop link performance.
