Joint Rate Control and Spectrum Allocation under Packet Collision Constraint in Cognitive Radio Networks

Abstract-- We study joint rate control and resource allocation with QoS provisioning that maximizes the total utility of secondary users in cognitive radio networks. We formulate and decouple the original utility optimization problem into separable subproblems and then develop an algorithm that converges to optimal rate control and resource allocation. The proposed algorithm can operate on different time-scale to reduce the amortized time complexity.
