一种无线浮标传感器网络覆盖优化算法的研究

无线浮标传感器网络是无线传感器网络应用于海洋监测领域的典型方式，而网络覆盖问题是衡量无线浮标传感器网络工作性能的重要指标之一。文中主要研究了一种适用于无线浮标传感器网络的覆盖优化算法。该算法的基本思想是在节点密集部署的监测区域中让每个节点与邻居节点交换信息以确定所要激活的最终候选节点，并将其他冗余节点设为休眠状态，以达到在所需的期望值下降低能量消耗的作用。不同网络规模的Matlab仿真结果分析可知该算法可以适当减少能耗，延长网络的寿命。

Study on Coverage Optimization Algorithm for Wireless Buoy Sensor Networks

Wireless buoy sensor network is a typical way of wireless sensor networks used in the field of marine monitoring,and network coverage is one of the important indicators to measure wireless buoy sensor network performance. The main aim is to present a coverage optimization algorithm for wireless buoy sensor networks. The basic idea of the algorithm is to make sensor nodes exchange information with their neighbors in the monitoring area to determine which ones to be finally activated, and other redundant nodes will be set to sleep- ing state, which can make coverage keep in the required expectations, reduce the energy cost. The results of Matlab simulation for different network size show that the algorithm may be appropriate to reduce the energy consumption and prolong the life of the network.
