Abstract:
The growing demand for wireless applications has driven research on technologies that can meet these needs. Cognitive radio (CR) is one such technology that enables shared spectrum usage. Communication in CR networks (CRNs) de-pends on the capabilities of the device, which can be full-duplex (FD) or half-duplex (HD). However, optimal routing for FD CRNs remains a challenge. This paper presents a routing protocol to improve network performance by minimizing time-sharing sessions using out-of-band FD (OBFD) communication. The protocol finds loop-free paths, computes transmission rates, and Probability of Success (POS) for each path, selecting the one with the highest POS. This optimization problem is converted from a binary quadratic problem (BQP) to a more solvable binary linear programming problem (BLP) using a polynomial-time sequential fixing method. The simulation results reveal that the proposed routing protocol significantly outperforms existing routing algorithms in terms of end-to-end throughput.
