In this paper, we investigate a novel two-hop multirelay cooperative wireless sensor network (WSN) based on simultaneous wireless information and power transfer (SWIPT). Specifically, we proposed a maximum energy efficiency relaying transmission scheme where the relay may keep silent or choose to deliver message in hybrid decode-amplify-forward (HDAF) protocol, according to the channel qualities. Note that the energy-constrained relays need to harvest energy from the ambient radio frequency (RF) signals radiated from the source, and the relay with maximum energy efficiency is selected. The closed-form expressions of the system performances, such as the outage probability, throughput and energy efficiency, are derived. Simulation results reveal the impacts of the energy conversion efficiency, time allocation factor, number of relay nodes as well as the channel fading parameters, on the performances. Compared with the DF and AF schemes, our proposed scheme effectively enhances the system energy efficiency.
