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 pros and cons of routing protocol based on ZigBee wireless sensor networks, selective improvement in the routing design. This paper introduces the structure of ZigBee wireless sensor network, analyzes the basic principles of three routing protocols AODV, LEACH and ZigBee routing, and uses NS2 simulation software to simulate ZigBee routing and AODV under the same external conditions, Taking energy consumption and network life cycle as indicators to measure network performance, simulation results show that ZigBee routing is higher in energy consumption than AODV, and the algorithm needs to be improved in energy conservation. The improvement of ZigBee routing algorithm in energy saving is pointed out.
