摘要
针对无线传感器网络实际应用中存在节点分布不均匀的情况,提出一种采用定向天线的无线传感器网络拓扑控制算法DATCA,算法充分利用了定向天线较高的能量效率及较强的干扰抑制等特性。本文利用有边界的帕累托分布构建节点分布模型,OPNET仿真结果表明:DATCA算法在保证网络连通性的同时,相比传统拓扑控制算法显著提高了网络的性能。
In order to solve the maldistribution for wireless sensor network,Topology Control Algorithm for WSN with Directional Antennas,DATCA is proposed,Algorithm takes full advantage of high energy efficiency and directional antenna interference suppression characteristics. Pareto distribution model will be built to compare the effectiveness between DATCA and traditional topology control algorithms. Simulation on OPNET results show that,under the pre-condition of ensuring the network connectivity,DATCA improves the performance of network.
