Simultaneous information and power transfer in wireless cooperative networks

Simultaneous wireless power and signal transfer is particularly important to communication scenarios with constrained energy, such as wireless sensor networks. This paper considers a wireless cooperative network with multiple pairs of sources and destinations communicating via a relay. The impact of various strategies of power allocation on the end-to-end transmission reliability in this cooperative network is studied. Both analytical and numerical results are developed to facilitate the comparison among the different power allocation strategies.
