Abstract—Radio-Frequency (RF) recharging of sensor nodes is a promising way to minimize maintenance and prolong the operational life of wireless sensor networks. In this paper, we present a simple MAC protocol based on polling that includes provisions for on-demand recharging using the same RF band as normal data communications, and we develop a probabilistic performance model to evaluate the impact of the recharging process on data communications under a range of values for bit error rate and traffic load.
