摘要
为了研究基于ZigBee的无线传感器网络路由协议的性能优劣,在路由设计中有选择地改进。介绍了ZigBee无线传感器网络结构,分析了AODV、LEACH和ZigBee路由三种路由协议的基本原理,并使用NS2模拟仿真软件,在其他外部条件相同的情况下,分别对ZigBee路由和AODV进行模拟仿真,以能量消耗和网络生命周期为衡量网络性能的指标,仿真结果表明ZigBee路由在能耗上高于AODV,算法在节能上有待改进。指出了ZigBee路由算法在节能上的改进方法。
In order to study the performance ZigBee-based wireless sensor network routing protocols,the selective improvement in the design of routing protocol is done.This paper describes the ZigBee-based wireless sensor network architecture,analyzes the principles of the three routing protocols as AODV LEACH and ZigBee.And the ZigBee and AODV routing protocols are simulated with NS2 simulation software under the same conditions.With energy consumption and network life cycle as a indicator of network performance,simulation results show that the ZigBee routing protocol is higher than AODV protocol in energy consumption while the algorithm should be improved in energy conservation.The paper suggests the energy-saving improvements on the ZigBee routing algorithm.
