摘要
节能是设计无线传感器网路由协议首先要解决的问题。针对无线传感器网拓扑演化过程所呈现的时空动力学特性,基于源自生物学的元胞自动机理论,提出无线传感器网节能路由协议(AODV-ECA)。仿真结果及分析表明,该算法能有效减少传感节点能量消耗,延长无线传感器网生存时间。
Since the battery equipped wireless sensors have limited energy supply, conserving energy to extend the lifetime becomes the most important requirement in the wireless sensor network （WSN）. An AODV routing protocol, AODV-ECA, was proposed, based on cellular automata （CA） mechanism, which was sourced from the thoughts of automatic breeding in biology. AODV-ECA could reduce and balance energy consumption to prolong the network lifetime by means of switching nodes＇ states between sleeping and working. Finally, AODV-ECA to other energy-efficient routing protocols by NS2 simulator was simulated and evaluated.
