In recent years, cognitive relay networks (CRNs) have emerged as a fantastic trend in research. It supports the establishment of a new communication network by spectrumsharing technique. However, most papers focus on studying the performance of the dual-hop scheme. This paper evaluates the proposed multi-hop model by giving the closed-form multihop network outage (OP). Simulation verifies our derivation and discovers the impact of several related factors on the secondary outage probability. We also highlight the end-to-end secondary multi-hop network by directly building the map to assist designers and operators on a network. |
