摘要: 为延长无线传感器网络(WSN)生存周期,引入无线能量补充设备,设计一种WSN基站部署策略。通过聚类传感器节点并计算每个区域传感器节点的通信量确定基站位置坐标,构建以最大化能量补充设备驻站时间比为目标的跨层优化问题,并将其转化为具有等优性的线性规划问题,实现传感器节点和无线能量补充设备的最佳配置。仿真结果表明,与固定基站部署策略相比,该基站部署策略可使无线能量补充设备的驻站时间比提升约75%。

Abstract: Devices for energy replenishment are introduced into Wireless Sensor Network(WSN) to extend its life cycle.To increase the vacation time of these devices,this paper designs a base station deployment strategy for WSN.First,clustering is performed on sensor nodes,and the total traffic of sensor nodes in each area is calculated to determine coordinates of base stations.Then the strategy constructs a cross-layer optimization problem aiming at maximizing the vacation time ratio of energy replenishing devices,and converts it into a linear programming problem of equal superiority to obtain optimal configuration of sensor nodes and wireless energy replenishing devices.Simulation results show that the proposed strategy can provide a 75% increase in vacation time ratio of wireless energy replenishing devices compared with fixed base station deployment strategy.

Key words: Wireless Sensor Network(WSN), wireless energy transfer, base station location, linear programming, Gaussian clustering
