A Modified Relay Selection Scheme in Opportunistic Relay Communications

Abstract-In this paper, we develop a modified relay selection technique in opportunistic relay communications. In this approaches, we use a threshold level between source and intermediate (M ) relay nodes. Then our proposed scheme can decreases the contending relay's collision probability. We compare the performance depending on different threshold level by using Monte Carlo computer simulation. Through this process, we verify the collision probability performance's analysis
