What is it about?

In this paper, we utilize the benefits of partial charging and distributed control, and present a game theory-based distributed mobile charging protocol (DMCP) to recharge sensor nodes in wireless rechargeable sensor networks using multiple mobile chargers. In particular, we formulate the mobile charging problem as a series of repeated games played among the MCs and represent a game as a 0 − 1 integer linear programming to maximize the total profit of the MCs. In each game, the DMCP dynamically determines the factor of charging of the energy-deficit SNs based on their relative criticality and selects the next-to-be-recharged SNs using an efficient bi-objective payoff function. Besides, it utilizes an innovative strategy and a self-enforcing agreement to promote cooperation among the MCs for their long-term mutual benefits.

Why is it important?

The proposed DMCP reduces the charging delay up to 44.04% and enhances the charging coverage and survival rate up to 45.12% and 49.97%, respectively.
