Abstract

In this paper, dual-hops and multi-hops cognitive radio Ad Hoc networks has been considered. It is vital mentioning that the primary user interference effect on the secondary user has also been considered. The design of the problem is to achieve an optimal solution for channel allocation and power in dual and multi hop in Cognitive Radio Ad Hoc Networks (CRNs). The main goal is to minimize the outage probability and increasing the length of your network life time, while simultaneously observing the transmission power constraints and the threshold of interference with the primary user. This problem was solved using the standard technique of solving convex optimization problem and weighted bipartite matching. All of the analysis is for both DF, and amplifying and transmission AF protocols. Comparison and measurement of the systems performance is outage probability. Simulation results have shown that the proposed scheme not only minimizes the outage probability compared to existing ones, but also reduces PU interference and saves overall transmission efficiency by Secondary Users.
