A Genetic Algorithm for Joint Resource Allocation in Cooperative Cognitive Radio Networks

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

Description

Existing literature in Cooperative Cognitive Radio Networks (CCRNs) always assumed a scenario where only one Primary User (PU) and several Secondary Users (SUs) coexist. However, in practice, multi-PUs and multi-SUs always coexist and the number of SUs is usually greater than that of PUs. Under such complex yet real scenarios, we assume that each PU not only allows a set of SUs to access its pre-allocated channel, but can leverage some of these SUs to improve its transmission rate via...[Show more]
