Outage probability of simultaneous wireless information and power transfer in heterogeneous information/energy ad hoc networks

Abstract

In this paper, we analyze the outage probability (OP) of simultaneous wireless information and power transfer (SWIPT) in heterogeneous ad hoc networks, where an energy ad hoc network and an information ad hoc network coexist and share a common spectrum resource. The receiving nodes with a single antenna are power-limited and therefore, each node either decodes the incoming information data (information decoding, ID) from information access point (IAP) or harvests the RF energy (energy harvesting, EH) from energy access point (EAP) (and possibly, IAP). When EAP and IAP with multiple antennas transmit energy/information signals with different power levels, we analyze the OP in the information/energy perspectives, which gives us a useful insight into the design of heterogeneous SWIPT-based ad hoc networks.
