Jaeyoung Lee, Hyundong Shin, Jun Heo · 2011
Multi-hop relaying over long distance is efficient to solve transmitter-power problem and mitigate wireless channel impairment. This paper provides a multi-hop relaying with Decode-and-Forward(DF) strategy in a wireless ad hoc network considering both noise and interference. Furthermore, we consider a realistic communication model where interferers are randomly scattered and uncoordinated with Poisson distribution. We analyze exact outage probability and spectral efficiency of a multi-hop DF relaying. From numerical results, multi-hop DF relaying has better performance than dual-hop relaying in terms of both outage probability and spectral efficiency.
