Abstract: In this paper, we consider optimal power allocation for link adaptive relaying systems with energy harvesting(EH) node. EH means source communicates with destination via EH Decode-and-Forward relay over the fading channels. We propose two types of relaying system. The first one is conventional relaying system, the source and relay transmit the signal in consecutive time slot and another one is buffer-aided link adaptive relaying system, the source-relay and relay-destination channels as well as amount of energy available at source and relay finding whether the source or relay is selected for transmission. Our main aim is to maximize the system throughput and to reduce the delay by using the technique is RSS. In both type of relaying system having offline and online power allocation method. Based upon this to analyses the performance gain and give the simulation result.
