最大化WSN寿命的电量分配与路由联合优化策略
Joint Optimization of Battery Allocation and Routing for Maximum Lifetime in Wireless Sensor Networks
摘要
Abstract
In order to prolong the lifetime of wireless sensor networks ( WSN ) , we jointly optimize the routing and battery allocation policy. The joint optimization problem is modeled with continuous and discrete battery levels re-spectively. In the case of continuous battery allocation,a linear programming problem is established,which obtains the optimal routing and battery allocation simultaneously. In the case of discrete battery allocation,a suboptimal but efficient method is proposed,which slacks a combinational optimization problem to a continuous form,and discretizes the battery levels in an optimal way. The simulation results show that our methods can substantially prolong the network lifetime and perform better than others.关键词
