Abstract :
Asymmetric transmission ranges caused due to transmit power control have the undesirable effect of increasing the number of hidden terminals in the network as well as increasing the unfairness in channel access. In this paper we present a new reactive power controlled MAC protocol, SHUSH, which tackles the above problems. We compare the performance of SHUSH with four other transmit power controlled MAC protocols and demonstrate that SHUSH achieves superior aggregate goodput, spatial reuse, fairness, and minimal energy consumption.
