【摘要】 针对无线传感器网络(WSN)节点能量均衡消耗的需求,提出一种基于均衡汇聚树的路由算法LB-CTP。该算法定义节点均衡度,引入规避繁忙节点接入机制。在路由更新中,相应节点以LB-CTP路由算法选择父节点接入网络,分担繁忙节点负担。基于TinyOS操作系统对LB-CTP进行实现,通过TOSSIM平台进行仿真实验,结果表明,与CTP算法相比,LB-CTP算法能有效地均衡网络负载。更多还原

【Abstract】 To meet the requirement of energy consumption balance between nodes of Wireless Sensor Networks(WSN),an improved Collection Tree routing Protocol(CTP) based on complete-balanced collection tree,called LB-CTP,is proposed,in which node balance level and busy node access avoidance mechanisms are defined.In order to share the burden of the busy node,the related node access to network according to LB-CTP routing algorithm in the routing setup stage.To evaluate the algorithm,the LB-CTP is implemented on the TinyOS and runs on TOSSIM simulation platform.Results show that LB-CTP can balance network load of WSN more effectively compared with CTP.更多还原
