On a Queue Backoff Fair Algorithm for Channel Access in Ad Hoc Network
Feng Jun-huan · Acta Simulata Systematica Sinica · 2004
Mobile Ad hoc network is a special multi-hop network without a centralized administration. Because of its speciality, direct application of the traditional CSMA protocol in Ad hoc network may cause the hidden terminal, exposed terminal and fairness problems. Based on the analysis of the existing backoff algorithms in Ad hoc networks access layer, this paper proposes a new simple yet effective queue backoff fair algorithm. Analysis and simulation results show that, by choosing appropriate parameters, the new algorithm can improve the channel access fairness and achieve a preferable trade-off between fairness and throughput degradation, compared with the IEEE802.11 Binary Exponential Backoff (BEB) algorithm and other algorithms.
