Distributed Uplink Power Control for Energy Harvesting Wireless Networks

In this paper, we study the power control problem for energy-harvesting wireless network (EHWN). In an EHWN, if there are some nodes whose energy- harvesting rate is less than its transmit power, power oscillation will be caused even when the system is feasible. In order to avoid the power oscillation, we take energy-harvesting node's energy status, i.e., energy-harvesting rate, transmit power and stored energy, into account and present a distributed power control algorithm. In our algorithm, some energy-harvesting nodes should be soft removed according to their inappropriate channel and energy status. Theoretical analysis, which is verified by simulation results, shows that our algorithm can avoid power oscillation, converge to a unique fixed point and bring less outage in both feasible and infeasible systems.
