【摘要】：针对ZigBee中路由算法AODVjr对于路径对称性和路由管理帧投递成功率依赖性过强的问题,提出了一种基于两层网络结构的无线传感器网络Mesh路由协议.路由算法统计路径上的路由管理帧统计丢包率作为路由判据,消除了管理帧丢失造成的影响;另一方面路由建立仅依靠管理帧的单向传输,降低了对于路径对称性的依赖;同时在Mesh网络下形成星型子网,在扩充网络容量的同时有效降低下层节点的资源消耗.给出了网络拓扑,建立了星型子网,分析了Mesh路由的信标帧、路由判据和路由建立过程,并用实际测试进行了性能分析.结果表明:相比于采用AODVjr路由算法的ZigBee协议,该协议在无线传感器网络中具有更高的数据传输可靠性,丢包率降低约30%.
[Abstract]:The routing algorithm AODVjr in ZigBee is too dependent on path symmetry and the success rate of routing management frame delivery. This paper presents a Mesh routing protocol for wireless sensor networks based on two-layer network structure. The routing algorithm uses the statistical packet loss rate of the routing management frame on the path as the routing criterion to eliminate the influence caused by the loss of managed frames. On the other hand, routing only depends on the one-way transmission of managed frames, which reduces the dependence on path symmetry, and forms star subnet under Mesh network. The network topology and star subnet are given, and the beacons frame, routing criterion and route establishment process of Mesh routing are analyzed. The results show that compared with the ZigBee protocol using AODVjr routing algorithm, this protocol has higher data transmission reliability and lower packet loss rate than that of ZigBee protocol in wireless sensor networks.
