Ad Hoc网络中优化功率控制技术浅析

Discussion on the technique of optimizing power control in Ad Hoc networks

移动AdHoc网络是一种工作在无固定设施环境下,由一组带有无线收发装置的移动终端节点组成的多跳的临时性的自治系统。在功率控制多址接入协议(PCMA)的基础上,分析了消除队头阻塞的PCMA+协议和S-PCMA协议。详细分析了PCMA+协议和S-PCMA协议的思想、机制以及对网络性能的影响。

A mobile Ad Hoc network（MANET）is a collection of wireless mobile nodes dynamically fomling a temporary multiple-hop network without the use of any central controller or existing net-infrastructure. Based on power controlled multiple access protocol （PCMA）, a MAC protocol without head-of-line blocking （PCMA ＋ ） and （S-PCMA） were analyzed. It presents a particular analysis to the idea, the mechanism, the effect to the network performance for the （PCMA ＋ ）and （S-PCMA）.
