摘要:

摘 要:利用无线充电设备周期地为无线传感器节点进行充电,可使传感器节点持续工作,解决无线传感器网络能量问题,但需设计合适的节点充电方案和网络路由方案。以无线充电设备驻站比最大化为优化目标,依次提出了充电及网络路由方案的连续时变模型、离散N+1 阶段非线性模型及可解的离散 N+1 阶段线性模型,在证明模型合理性后最终求解。结论给出了具体网络的最优充电和路由策略。

Abstract:

The energy problem of wireless sensor networks could be solved by recharging sensor nodes periodically through the wireless energy transfer technique,which ld made sensor nodes remain optional persistently.However,appropriate charging and routing strategies were also in great needs.According to the optimization object of maximizing the vacation time ratio of a wireless charging equipment,the continuous time-varying model,the discrete (N+1)-phased nonlinear model and the solvable discrete (N+1)-phased linear model for the charging and routing strategy were proposed successively.The feasibility of these models was proved as well.In conclusion,after solving the last proposed model,the optimized charging and routing strategies were obtained for networks in different scales.

Key words: wireless sensor networks, wireless energy transfer technique, charging cycle, continuous time-varying model, discrete (N+1)-phased model, linear program
