Optimum Relay Selection using OSBO Algorithm for Cooperative Transmission Networks

Abstract

Cooperative networks are widely used in the field of wireless communication technologies. Cooperative communication networks use relaying techniques such as Quantize-and-Forward (QF), Decode-and-Forward (DF), and Amplify-and-Forward (AF) to enhance communication reliability throughout the performance. To improve the signal-to-noise ratio (SNR) at the receiving end, relay systems employ relay nodes that take in data, process it, and then resend it. To enhance the overall efficiency of the system, we recommend adopting bidirectional communication approaches in which two parties transmit and receive data over distinct relay nodes. This study employs the Opposition-based Satin Bowerbird Optimization (OSBO) technique to propose a way of determining the appropriate relay to be employed in cooperative communications. The Relay Selection (RS) process is based on a set of constraints such as Outage probability, collision probability, Bit Error Rate (BER), and Energy consumption during cooperative communication. After selecting the best relay nodes using OSBO, the DF technique is applied at each relay node. The suggested Optimum Relay Selection using the Opposition-based Satin Bowerbird Optimization (ORS-OSBO) approach achieves the lowest possible delay and outage probability while increasing the packet delivery rate and Residual Energy (RE).
