摘要: Abstract In this paper, we consider a scenario where the source node powered by conventional power grid transmits data with assistance of some energy harvesting (EH) decode-and-forward (DF) relay nodes. Unlike EH providing renewable energy, most grids are supported non-renewable fossil fuels. So our goal is to maximize efficiency (EE) non-EH throughout multiple timeslots. To deal randomness arrivals and non-ideal circuit power, formulate EE optimization problem relaying system combining allocation sleep mode in both relay. We firstly special case just one timeslot then solve it multi-timeslot dynamic programming (DP) approach. also propose heuristic algorithm complexity lower than DP algorithm. compare performance two algorithms baseline scheme. Simulation results show that provides close algorithm, significant gain over
