摘要

In this paper, we present an approach to ensure efficient energy distribution among all the nodes in a wireless sensor network by employing mobile chargers from several landmark locations within each sensor cluster with timing constraint. Mobile chargers are considered to use radio frequency signals for the charging purpose and use Hamiltonian cycle to ensure minimum time required to visit landmarks within each sensor cluster. This scheme helps increase the docking time compared to the total cycle time for the mobile chargers to get recharged from the docking station. It also increases the battery lifetime for the sensors which is one of the major bottleneck for wireless sensor networks. The optimum number of landmarks for each cluster is selected with the help of critical nodes whose energy goes below the defined threshold. Later, the mobile chargers calculate the minimum distance among the landmarks and initiate the energy transfer by certain percentage from their own reservoirs. The simulation results show that the proposed approach successfully provides prolonged lifetime for the sensor battery, less waiting time for the sensor nodes to get recharged from the mobile chargers, and maximize docking time for the mobile chargers.
