Channel reservation MAC protocol with adaptive power control mechanism carrier sensing
摘要
Abstract
vA channel reservation MAC protocol with the adjustable transmission power and carrier sensing threshold, called PC-CRM, is proposed. PC-CRM solves the problems of poor transmission quality, low network capacity and high energy consumption, which are caused by the distributed contention based channel access scheme in Ad Hoc networks. By employing power control into the channel reservation schemes, PC-CRM adjusts the transmission power and carrier sensing threshold to the optimum values, such that the channel is multiplexed in space. Additionally, PC-CRM is also capable of stabilizing the channel reservation, improving the network capacity, and reducing the energy cost. Simulation results show that, compared with IEEE 802. 11DCF and the basic channel reservation scheme, PC-CRM performs better in terms of the throughput, energy efficiency and delay jitter.关键词
