摘要

针对ZigBee网络混合路由算法的不足

考虑低速无线个域网(LR-WPAN)网络的能耗问题

提出了一种基于ZBR路由协议的改进算法(F-ZBR)。本算法通过定义最小路由能量值和控制路由请求分组(RREQ)的传输方向、跳数以及在RREQ分组中加入能量标志位等措施

降低网络的整体能耗。仿真结果表明

F-ZBR算法的分组投递率、网络可用节点比率和网络剩余能量都较ZBR有明显提高

从而可以延缓ZigBee网络中大量数据传输造成的RN+节点能量过度损耗而导致的网络瘫痪等问题的发生

延长网络生命周期。

Abstract

An enhanced algorithm named F-ZBR was proposed considering the weakness of ZigBee hybrid routing algorithms and the energy consumption in LR-WPAN network.The proposed scheme reduced overall energy consumption of network by the definition of minimum routing energy and controlling the direction of RREQ packet as well as the number of hop

besides the introduction of energy flag in RREQ packet.The analysis on simulation result indicated that F-ZBR performs significantly better than ZBR in packet delivery ratio

available nodes ratio as well as remaining energy ratio.By the algorithm

therefore

it may be depleted that huge data transmission gives rise to over-consuming energy of RN+ nodes or even collapse in ZigBee network.And the algorithm also prolongs the life span of network.
