【摘要】：针对可充电无线传感网络中的能量均衡路由问题,提出在稳定功率无线充电和监测数据收集网络场景下的多路径路由算法和机会路由算法,以实现网络的能量均衡。首先,通过电磁传播理论构建了无线传感节点的充电和接收功率关系模型;然后,考虑网络中无线传感节点的发送能耗和接收能耗,基于上述充电模型将网络能量均衡的路由问题转化为网络节点运行时间的最大最小化问题,通过线性规划得到的各链路流量用以指导路由中数据流量分配;最后,考虑一种更加现实的低功耗的场景,并提出了一种基于机会路由的能量均衡路由算法。实验结果表明,与最短路径路由(SPR)和期望周期最短路由(EDC)算法相比较,所提出的两种路由算法均能有效提高采集能量的利用率和工作周期内的网络生命周期。
[Abstract]:To solve the problem of energy balanced routing in rechargeable wireless sensor networks, a multi-path routing algorithm and an opportunistic routing algorithm are proposed under the scenario of stable power wireless charging and monitoring data collection network. In order to achieve the energy balance of the network. Firstly, the charging and receiving power relationship model of wireless sensor nodes is constructed by electromagnetic propagation theory. Then, considering the transmission and receiving energy consumption of wireless sensor nodes in the network, the routing problem of network energy balance is transformed into the maximum running time minimization problem based on the above charging model. Each link traffic obtained by linear programming is used to guide the data flow allocation in the route. Finally, a more realistic low-power scenario is considered, and an energy-balanced routing algorithm based on opportunistic routing is proposed. Compared with the shortest path routing (SPRP) algorithm and the expected cycle shortest routing (EDC) algorithm, the proposed two routing algorithms can effectively improve the utilization rate of acquisition energy and the network lifecycle in the working cycle.
