中文摘要：

为了降低异构无线传感器网络的能耗，提高网络吞吐量。综合Chain—Based协议和SEP协议的优点，在给定一种新的异构网络环境下，提出了一种基于簇链式的异构WSN路由协议。首先基站依据地理位置将监测区域划分成簇，然后簇内节点按照最近距离成链。在簇头的选取阶段，以节点的剩余能量与所在区域的平均能量选取候选簇头，接着按照给定的阁值选取最终簇头节点和Leader节点。对比仿真结果表明，该协议对网络能耗、吞吐量和生命周期的优化都优于Chain—Based协议和SEP协议。

英文摘要：

The present study aims to reduce the energy consumption of heterogeneous wireless sensor networks and improve the network throughput. Based on the advantages of Chain - Based protocol and SEP protocol, a new routing protocol of heterogeneous WSN based on cluster chain is proposed in the context of a new heterogeneous network. The first base station based on the geographical position the monitoring region is partitioned into clusters, and cluster nodes according to the distance to the nearest chain. In the selection of cluster head, the candidate cluster head is selected by the residual energy of the node and the average energy of the region, and then the final cluster head node and the leader node are selected according to the given threshold. Simulation results show that the proposed protocol is superior to the Chain - Based protocol and SEP protocol in the network energy consumption, throughput and life cycle.
