Optimal resource allocation for cognitive radio networks with primary user outage constraint

Optimal and sub-optimal resource allocation in multi-hop cognitive radio networks with primary user outage constraint

In this study, the authors propose a cross-layer optimisation framework for cognitive radio networks (CRNs) by jointly taking into account the physical layer and transport layer. In particular, they focus on joint rate and power control for a multi-hop CRN to maximise the network utility without affecting the performance of primary users (PUs). The formulation is shown to be a non-linear non-co...

Adaptive Resource Allocation for Cognitive Radio Networks with Multiple Primary Networks

In this article, adaptive resource allocation (ARA) is investigated for multiple primary networks based-cognitive radio networks under a more practical system model, where the bandwidth of each secondary user is assumed to be limited and the maximum allowable interference for each primary network is different. We first formulate the ARA as a constrained optimization problem with the objective f...
