Novel distributed algorithm for coalition formation in cognitive radio networks for throughput enhancement using matching theory

Abstract: In this paper, a novel algorithm is proposed for increasing the throughput in cognitive radio networks by forming coalitions among cognitive radio users in AWGN and fading channel environment. Although there have been numerous studies exploring the benefits of coalition formation in cognitive radio networks from the game theory perspective, there are several limitations in their application. To overcome the limitations of game theory, concepts from matching theory are used. Specifically, the stable marriage pr… Show more

“…The proposed game is based on a merge‐only method that incorporates a handover or power control interference schemes. A stable marriage algorithm [35] is proposed for increasing the throughput in CRNs by forming coalitions among SUs in additive white Gaussian noise (AWGN) and fading channel environment. This algorithm formulates stable coalitions and provides significant improvement in terms of reduced Pnormalfi and improved throughput per SU.…”

“…Average power P m can incorporate the effects of fading and shadowing, and P m = σ 2 sm . Consistent with [21], we define P m = µP/d α m , where P is the PU transmitted signal power, d m is the distance between PU and SU m . Moreover, µ is a unitless constant that depends on the antenna characteristics, and α is a path-loss exponent, respectively.…”
