多Sink协同移动的最大化网络生存期优化算法
Multiple Sinks Cooperative Mobility Optimization Algorithm to Maximize the Lifetime in Wireless Sensor Networks
摘要
Abstract
According to the problem of energy hole which caused by unbalanced consumption in wireless sensor networks (WSN), the paper proposes the multiple Sinks cooperative mobility optimization algorithm to maximize the lifetime for wireless sensor networks. In this algorithm, the interest region is divided into a quantity of virtual cells. It cooperates with ACO(Ant Colony Optimization) in the mobility of multiple Sinks based on network conditions. The time of Sinks sojourning at optional sites is converted to LP( Linear Program) and extending the lifetime of network. Simulation results indicate that LP-ACO ( Linear Program-Ant Colony Optimization) is effective on balancing the energy consumption It not only makes the network lifetime significantly longer than static, deployment ( STATIC) and random movement( RDM)of Sinks,but also more scalable.关键词
