Outage performance of time switching energy harvesting wireless sensor networks deploying NOMA

Abstract

Thanks to the benefits of deploying non-orthogonal multiple access (NOMA) in wireless communications, i.e, wireless sensor networks, we evaluate an energy harvesting wireless sensor network (EH-WSN) deploying NOMA, where the destination can receive two data symbols the whole transmission process with two time slots. To be more clear, we derive expressions for the achievable data rate and outage probability. In addition, we present Monte-Carlo simulations to prove the performance and the correctness of the obtained numerical results.
