| 摘 要： | 基于PEGASIS和EPEGASIS链状结构路由协议的不足,本文提出新的一种分层多链无线传感器网络路由协议。通过基站将整个监测区域划分成数个扇形环带区域进而形成多链结构。依节点间的距离公式利用贪婪算法进行建链,避免相邻节点间长链的产生,链头节点的选取考虑了节点剩余能量以及节点到基站的距离。仿真结果表明,算法在减少网络延迟以及延长网络生命周期方面优于PEGASIS和EPEGASIS协议。

| Abstract: | In this paper we propose a new multi-chain hierarchical routing protocol due to the inadequacies of PEGASIS and PEGASIS protocols.According to the method mentioned in the literature6],we divide the whole monitoring domain into numerous sector zones to form a multi-chain structure through the base station.When constructing the chains,we use greedy algorithm according to the distance formula to prevent the longer chains between the adjacent nodes,which are chosen by considering the residual energy of nodes and the distance from the nodes to the base station.The simulation result shows that the algorithm is better than PEGASIS and PEGASIS protocols in reducing the network delay and prolonging the network lifetime. |
