Most of the current research about wireless rechargeable sensor networks (WRSNs) only focus omnidirectional charging, which has a lot of limitations in real environment. With the introduction of a mobile chargers with adjustable direction, the omnidirectional charging path planning can be transformed into the directed charging path planning of wireless rechargeable directed sensor network (WRDSN). To achieve this goal, the authors proposed a heuristic algorithm, i.e. the sensor nodes are partitioned into several local subsets by DMC, and a motion path is initialized. Then the DMC cruise problem in WRDSN is transformed into a charging utility maximization problem, and path is optimized from a global perspective. A large number of numerical results show that our proposed algorithm outperforms some existing algorithms.
