摘要/Abstract

摘要：

提出了一种动态调整发送功率和载波侦听门限的信道预约多址接入协议(PC-CRM)．该协议将功率控制技术应用于信道预约机制，通过对预约节点发送功率的优化设定和载波侦听门限的动态调整，使得相邻节点可以同时复用信道，从而在增强预约稳定性的基础上，提升了网络容量，降低了节点能耗．仿真结果显示，与IEEE 802.11 DCF和基本信道预约协议相比，PC-CRM协议在网络吞吐率、能量消耗效率和分组延迟抖动方面均有明显优势．

Abstract:

A 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.

Key words: Ad Hoc network, MAC protocol, channel reservation, power control
