Finally, here comes the conclusion. To improve the survival rate of sensor nodes and energy usage efficiency, we have proposed a temporal spatial partial charging scheme for WRSN with multiple mobile chargers in this paper. Our charging strategy, termed TSPC-DRL, automatically determines the charging duration of the target charging node. Our proposed scheme has promising performance in prolonging the survival rate of the sensor node and improving the energy usage efficiency of MC compared with the baseline algorithms, which has been verified by the simulation experiments. Our future research will focus on designing a multi-node charging scheme for multiple MCs in WRSN.
