Outage Probability Performance Analysis of a New Hybrid Relay Selection Protocol
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2017, Vol 19, Issue 1
Abstract
In this paper, the diversity gains of wireless relay networks were exploited. The proposed cooperative scheme using the first best relay for providing the highest SNR at the destination, whereas the second best relay is used for suboptimal SNR at the destination. The source communicates with the single antenna destination, with the help of multiple AF relays, equipped with a single antenna. Specifically, the BEP and outage probability performance of AF cooperation with the first and second best-relay selection scheme were investigated. Analysis proves that multiple antennas at the source node with best-relay selection can achieve full diversity for transmission, which significantly improves the received quality at destination. In particular, closed-form expressions for the probability density function (PDF) and cumulative density function (CDF) of SNR at the destination are derived. Subsequently, closed-form expressions for the outage probability are obtained.
