摘　　要：应用于输电线路在线监测的无线传感器网络(WSNs)通常呈长链型,存在跳数多、时延大的问题。引入具备无线公网通信模块的异构节点能够优化WSNs时延性能。考虑网络中传感器节点分布不均匀引起的数据分布不均匀这一普遍现象及其对时延的影响,建立了异构WSNs的最大时延模型;同时考虑网段划分和异构节点部署对时延的影响,提出了一种基于局部搜索思想的网络优化部署方法来优化网络时延。仿真结果表明:上述方法能有效降低网络最大时延,提高网络实时性。Long-chain wireless sensor networks （WSNs）used in transmission line online monitoring presents some problems such as many hop counts and large delay. To optimize delay performance of WSNs, heterogeneous nodes that can communicate through wireless public network are brought in. Considering the uneven distribution of data caused by uneven deployment of sensor nodes, and effect on delay build the maximum delay model of heterogeneous WSNs; then considering that the network segments partition and effect of heterogeneous nodes deployment on delay, network optimization deployment method based on local search idea is proposed to optimize network delay. Simulation results indicate that the proposed method can effectively decrease the maximum network delay and improve the real-time of WSNs.
