摘　　要：This paper considers link scheduling in a wireless network comprising of two types of nodes:(i)hybrid access points(HAPs)that harvest solar en-ergy,and(ii)devices that harvest radio frequency(RF)energy whenever HAPs transmit.Our aim is to de-rive the shortest possible link schedule that determines the transmission time of inter-HAPs links,and uplinks from devices to HAPs.We first outline a mixed in-teger linear program(MILP),which can be run by a central node to determine the optimal schedule and transmit power of HAPs and devices.We then out-line a game theory based protocol called Distributed Schedule Minimization Protocol(DSMP)that is run by HAPs and devices.Advantageously,it does not require causal energy arrivals and channel gains in-formation.Our results show that DSMP produces schedule lengths that are at most 1.99x longer than the schedule computed by MILP.
