摘　　要：无线传感器网络(WSN)由若干个传感器节点通过多跳自组织的方式构成,这些节点的能量和处理能力都受到极大地限制,因此研究节能高效的路由协议具有较大的意义。为延长WSN的生存时间和提高网络吞吐量,提出了一种能耗均衡的WSN高吞吐量路由协议,该协议利用K⁃means聚类算法对节点进行分簇,并结合节点剩余能量和距离计算权重值,选择最佳节点作为簇首,此外,还利用无线收发器的参数和信道状况确定最佳固定分组大小。在数据传输阶段,使用Dijkstra算法计算多目标权重函数作为链路成本。实验结果表明该方案在网络节点节能方面优于CERP和TEEN路由协议,且提高了整个系统的吞吐量和生存时间。The wireless sensor network(WSN)is composed of sensor nodes organized by multi⁃hop self⁃organization.However,the energy and processing capabilities of these sensor nodes are greatly restricted.Thus,it is of great significance to study energy⁃saving and efficient routing protocols.In order to prolong the lifetime of WSN and improve network throughput,a high⁃throughput routing protocol for WSN with balanced energy consumption is proposed.K⁃means clustering algorithm is used to cluster nodes,the weights are calculat⁃ed based on the remaining energy and distance,and the best node is selected as the cluster head.In addition,the optimal size of the package is determined based on the parameters and channel conditions of the wireless transceiver.In the data transmission stage,the Di⁃jkstra algorithm is used to calculate the multi⁃objective weight function as the link cost.Experimental results show that the proposed pro⁃tocol is better than CERP and TEEN routing protocols in terms of energy saving of network nodes,and it improves the throughput and survival time of the entire system.
