摒弃无线传感器网络(wsNs)层次路由协议中轮询的工作方式,提出一种改进的基于独立重建簇的无线传感器网络层次路由协议,IRC-HRP协议。协议通过对所有节点设置层次号(ANum)和簇号(CNum)进行标识,保证簇与簇之间都是相互独立的,重组只在某个簇内进行,而不影响其它状态良好簇的正常工作和整个网络的拓扑结构。同时在数据传输过程中,协议利用层次号保证数据传输路径都统一指向sink,不会出现回路、绕路,可以有效提高数据传输的效率。通过与现有的层次路由协议进行比较并做仿真验证,表明了文中提出的协议可以有效的节约网络能耗和延长整个网络的生存周期。
The round robin in the hierarchy routing protocol for WSNs is abandoned, an independent reconstruction of a cluster based on hierarchy routing protocols of WSNs, IRC-HRP protocol is improved. The protocol sets layer number (abbreviated as ANum) and cluster number (abbreviated as CNum) of all nodes for identification numbers to ensure independent of each other a- mong clusters, reconstruction only in a cluster without affecting the other clusters to work in good condition, and the whole net- work topology. While the data is transferred, ANum is used to ensure a unified point data paths sink (base station), will not loop and detour and the efficiency of data transmission is improved. Finally, the protocol with the existing level and do the simu- lation, the proposed protocol can effectively save network energy consumption and prolong the lifetime of the entire network.
