摘要
ZigBee网络采用簇树(Cluster-Tree)路由和AODV-jr路由相结合的混合路由策略,在具体路由策略中如何平衡这两种路由模式以达到更好的性能值得研究;此外,ZigBee规范中很少涉及能量控制问题;通过分析上述两种路由模式的性能,提出了一种基于数据服务的路由策略,同时还提出了一种能量控制机制来提高ZigBee路由的性能;仿真结果表明该路由策略具有良好的网络性能和较低的功耗,同时能量控制策略可以很好地平衡节点的能量,避免节点电池能量过早耗尽。
ZigBee network use a mixed routing strategy of cluster--tree routing and AODV--jr routing, but it is important to design a method to balance these two routing modes in order to achieve better performance. Additionally, the power control is not much considered in ZigBee specification. This paper proposes a routing strategy based on data services by analyzing these two routing modes mentioned above and a power control mechanism is also proposed to improve the ZigBee routing. The simulation results show that such routing strategy has outstanding network performance and low energy consumption and such power control strategy can greatly balance the node energy and avoid nodes use up all battery power too early.
