Abstract :
The drive towards portable wireless devices capable of forming ad-hoc wireless networks on demand has spurred significant interest in the design and analysis of power-efficient schemes at all layers of the protocol stack. In order to increase useful lifetimes of such battery-powered devices, it is vital to understand the role of carrier-sense based multiple access protocols in controlling the trade-offs between throughput and energy consumption performance. Our focus in this work is the impact of imperfect carrier sensing on this trade-off; accordingly, we present an analysis of the energy efficiency of p-persistent CSMA with carrier sense imperfections
