In this paper, we consider an energy harvesting (EH) decode-and- forward (DF) based two-hop cooperative network with a direct link. The energy-buffer equipped relay harvests energy from the ambience, and uses the harvest-store-use (HSU) architecture. Since it is known that using a discrete-state Markov chain to model the energy buffer is inaccurate even for moderate number of states, we assume use of a discrete-time continuous-state space Markov chain. We derive the limiting distribution of energy for the incremental best- effort policy (IBEP) and use that to obtain expressions for outage probability and throughput. We also compare performance with non- incremental best-effort policy (NIBEP) which is a special case of the analysis presented here, with harvest-use (HU) and direct transmission (DT). Sim- ulation results are presented to validate the derived analytical expressions.
