Algorithms for joint spectrum allocation and cooperation set partition in cognitive radio networks

Yang, Wei; Ban, Dongsong; Liang, Weifa; Dou, Wenhua

Description

The coexistence of multi-primary users and multi-secondary users in cooperative cognitive radio networks motivate the study to propose a joint spectrum allocation and cooperation set partition problem, which so far has not been addressed before. The problem is formulated as a 0-1 integer non-linear programming model. Due to its NP-hardness, the study proposes a suboptimal Centralized Genetic Algorithm (CGA) to show its convergence by modeling it as a homogeneous finite Markov chain. The study...[Show more]
