摘要 为了解决无线传感器网络(WSN)的路由问题,在分析了单路径路由协议和多路径路由协议的基础上,提出了节点覆盖层次模型。该模型根据节点到sink节点的最小跳数将网络分成以sink节点为中心的层次结构,并将邻居节点分成父节点、兄弟节点和子节点3类。并设计了在此模型下的路由协议MP-NCL。在该协议中,节点总是将感应到的数据向父节点转发,实现了跳数最小、多路径的数据传递。分析和仿真结果表明,节点覆盖层次模型和MP-NCL路由协议在延时、耗能、可靠性和生命期方面有较好的性能。 For solve the problem of routing in wireless sensor networks,this paper proposes node-cover layer model by analyzing the single path routing protocol and the multi-paths routing protocol.The model layers the network based on the minimum hop of sensor nodes to sink node,and the sink node is the center of the layered network.The model divides the neighbors as fathernodes,brother-nodes and son-nodes.MP-NCL,proposed based on node-cover layer model,ensures the data packets transmitted down minimum hop,muhiple paths and forwarded between the father-nodes in paths.The results of analysis and experiments show node-cover layer model and MP-NCL routing protocol have outstanding performances in packets delay, dissipated energy,reliability and lifetime of network.
