基于能耗均衡的ZigBee火灾监控系统路由算法

摘要

In ZigBee network,the traditional routing algorithms just reduce the energy consumption of the network,but ignore the network energy consumption imbalance leads to the depletion of the local network energy,resulting in the problem of network paralysis.To solve this problem,this article puts forward a routing algorithm considering residual energy and energy threshold,starting from the energy consumption balance of network nodes.Experiments show that this algorithm can effectively slow node of the time of death,prolong the network lifetime greatly.%在ZigBee网络中,传统的路由算法单纯的减少网络的总体能耗,而忽略了网络能耗的不平衡导致局部网络能量的枯竭,致使网络瘫痪的问题.针对这一问题,文中从网络中节点能耗均衡出发,提出了一种将剩余能量和能量阈值综合考虑的路由算法.实验表明,该算法能有效地减缓节点的死亡时间,大大延长网络寿命.
