研究问题为引入无线能量补给设备后，多基站无线传感器网络的跨层优化问题。以设计无线传感器网络中的数据路由、传感器节点的功率控制及无线能量补给设备的工作策略为研究目标，通过提出无线传感器网络中传感器节点活跃度的概念，分析无线传感器网络物理层与网络层需要满足的约束条件，结合无线能量补给设备需要满足的约束条件，提出可充电无线传感器动态网络跨层优化问题，并将其转化为易于求解的线性规划问题。根据求得的最优解获得无线传感器网络中传感器节点动态且周期的数据路由及功率控制策略，并得到无线能量补给设备周期性工作策略，且无线能量补给设备驻站时间比较之前研究成果提升在100％以上。

The cross-layer modeling and optimization for rechargeable wireless sensor network with multiple base sta-tions are researched in this paper.In order to develop the working scheme for wireless sensor node as well as wireless energy transfer device, physical and network layer constraints that wireless sensor node and wireless energy transfer device must comply with are elaborated here.The cross-layer optimization problem of dynamic networking is formula-ted in order to maximize the index of sensor node activity which is presented here.Furthermore, the cross-layer opti-mization problem with variables, which are continuous functions of time, is reshaped into a linear programming prob-lem by deduction.In the simulation and numerical analysis, the dynamic and cyclic working strategies for wireless sensor node and the wireless energy transfer device are revealed after solving the linear programming problem.The vacation time ratio of the wireless charging device is increased by more than 100%compared with former researches.
