摘要
文章研究了最小跳路由下可充电无线传感器网络的建模和优化问题,分析了可充电无线传感器网路的拓扑连通性,并依据Dijkstra算法给出了该网络的最小跳数路由算法。在给定数据路由的前提下,提出了可充电无线传感器网络中针对能量补给设备驻站时间比的优化问题,并将其转化为易于求解的线性规划问题,最终得到无线传感器节点和无线能量补给设备的工作策略。
The modeling and optimization of rechargeable wireless sensor networks with minimum hop routing schemes are studied. The topological connectivity of rechargeable wireless sensor networks is analyzed,and the minimum hop routing scheme is obtained via Dijkstra algorithm. The optimization problem for maximizing the vacation time ratio of wireless energy transfer device is proposed in ac- cordance with the data routing adopted. Then the original optimization problem is transformed into a linear programming problem with identical optimality, which can he solved efficiently. Finally, the optimal working schemes for wireless sensor networks and wireless energy transfer device are obtained.
