基于树路由的节能算法研究

Energy Saving Algorithm Research Based on Tree Routing

ZigBee网络的能耗问题一直是研究的一个热点,在实际工作环境中ZigBee网络中的某些节点因频繁用到而过早的能量耗尽,使网络性能降低或瘫痪。该文针对这些问题,对树路由算法进行了改进,改进路由算法通过引入邻居表和能量分级机制,控制节点能量消耗,保护能量较低的节点,使网络的生存能力更长。仿真实验表明改进算法节约了数据包传输的能量消耗,避开了能量较低节点,使整个网络更加高效、长久的工作。

ZigBee network energy consumption problem is always a hot spot of research.In an actual working environment,some nodes of ZigBee network were used frequently and soon ran out of energy,so the network would perform depressed or paralytic.Aiming at these problems,the paper on tree routing algorithm was improved.The improved routing algorithm by introducing a neighbor table and energy grading mechanism,controlled node energy consumption and protected the lower energy of node,making the network ability to survive longer.The simulation results show that the proposed algorithm saves the data packet transmission energy consumption,avoid low energy node,and make the entire network work more efficient,more long-term.
