Energy harvesting aware topology control with power adaptation in wireless sensor networks

摘要: In the recent years, energy harvesting technology has been integrated into wireless sensor networks for resolving "bottleneck" problems caused by limited-capacity batteries equipped in traditional nodes. However, due to limited capacity of buffers storing harvested energy, excessive is indiscreetly discarded while nodes are staying at status saturation. To address this issue, we present a topology control approach, network, that allows each node adaptively adjust its transmission power utilizing effectively. Specifically, first model behaviors as an ordinal potential game where high cooperate with low maintain connectivity whole network. And theoretically prove existence Nash equilibrium game. Then, polynomial-time algorithm proposed achieve equilibrium. Simulation results show our scheme improves availability and outperforms existing energy-aware schemes terms conservation balanced distribution.
