Outage Performance of Underlay Multihop Cognitive Relay Networks with the use of the highest Power Beacon among Power Beacons

Abstract

This paper studies the outage performance of multihop cognitive relay networks with energy harvesting in underlay paradigms, wherein the secondary users are powered by a dedicated power beacon (PB) have the highest energy level among their power beacons and the interference constrain from the primary user. The author derived the exact outage probability for Rayleigh block fading and prove that the outage probability is monotonically decreasing with respect to the transmit power of PB. Furthermore, the author drew conclusions when the author compared the outage performance of the system in 3 cases: the system without using the beacon, the system using a power beacon, using a beacon with the highest energy level among power beacons. Simulation results validate the theoretical results.
