摘　　要：无线传感网络是由大量传感节点构成的分布式自组织网络,而传感节点采用电池供电,其有限的能量严重影响了网络的生存周期。本文提出了一种新的异构感知路由协议(ED-SEP),该协议在分簇阶段综合考虑节点的剩余能量和覆盖半径范围内邻居节点的疏密程度及与基站的相对距离大小,从而选举出更具优势的簇首。采用MATLAB仿真分析了ED-SEP协议在改变基站位置和节点初始能量下的性能表现,并与稳定选举协议SEP、E-SEP进行比较。结果表明:通过改变网络中的参数,ED-SEP协议的网络稳定期相比SEP协议和E-SEP协议分别提高了29.6%和25.7%,基站的数据接收量达到了E-SEP协议的近3倍,有效提高了网络的能量利用率,极大地改善了无线传感网络的性能。Wireless sensor network(WSN)is a distributed self-organizing network composed of a large number of sensor nodes.The sensor nodes are powered by batteries,and their limited energy seriously affects the life cycle of the network.In this paper,we introduced a new heterogeneous awareness routing protocol to elect a more reasonable cluster head,which comprehensively considers the residual energy of the node,the density of neighbor nodes and the relative distance to the base station within the coverage radius in clustering stage.We used the MATLAB R2016b simulator to analyze the performance of ED-SEP protocol under the condition of changing the base station location and the initial energy of the node,and it is compared with the stable election protocols.Simulation results show that the network’s stable period of ED-SEP protocol is increased by 29.6%and 25.7%respectively compared with SEP protocol and E-SEP protocol,and the data receiving capacity of base station is nearly three times that of E-SEP protocol.Therefore,the ED-SEP algorithm can effectively improve the energy utilization rate of the network and greatly improve the performance of the wireless sensor network.
