This paper proposes a charging-aware multi-mode routing protocol (CMRP) to collect data in the wireless rechargeable sensor networks. The routing mechanism in CMRP is not steady but changes according to the energy charging status of sensors. Sensors that cannot replenish their energy efficiency use the routing protocol with less energy consumption. On the contrary, sensors that can replenish their energy use the low propagation delay routing protocol. A novel heuristic chaining mechanism based on multi-level convex hull circle (MCC) is also proposed. Simulation results show that CMRP not only has longer operation time than LEACH and PEGASIS but also has the shortest propagation delay time. The lifetime of CMRP is less than the minimum spanning tree by about 1%, but the propagation delay is shorter than MSTP about 21-28%. In addition, CMRP considers both reducing energy consumption and shortening the propagation delay at the same time. The life-delay rate of the CMRP is close to the optimal results.
本文提出了一种充电感知多模式路由协议（CMRP），用于在无线可充电传感器网络中收集数据。CMRP中的路由机制并不稳定，而是根据传感器的能量充电状态而变化。无法补充其能量效率的传感器使用能耗较低的路由协议。相反，能够补充能量的传感器使用低传播延迟路由协议。还提出了一种基于多级凸包圆（MCC）的新型启发式链机制。仿真结果表明，CMRP不仅比LEACH和PEGASIS具有更长的运行时间，而且具有最短的传播延迟时间。CMRP的寿命比最小生成树短约1%，但传播延迟比MSTP短约21-28%。此外，CMRP同时考虑了降低能耗和缩短传播延迟。CMRP的寿命延迟率接近最优结果。
