Abstract
Physical layer security is the foremost concept for providing security to a wireless communication network. Three-hop wireless relaying model consisting of single source and destination node, along with two relay nodes and an eavesdropper, is analysed in this paper. Performance analysis of this multi-hop network is done by comparing different parameters of it with a conventional single-hop wireless model. The results demonstrated that secrecy rate improves by increasing the distance between relay and eavesdropper (R-E) and distance dE for all the cases. On the other hand, it is found that the increase in relay-to-destination distance dRD and distance dEH results in decreasing secrecy performance. Furthermore, an increase in value of path loss exponent degrades the system’s performance. For all cases, AF protocol improves secrecy rate by 11.9% for single-hop while 42.86% for multi-hop scenario as compared to DF protocol.
