Joint On-Demand Routing and Spectrum Assignment in Cognitive Radio Networks
In cognitive radio networks, nodes can work on different frequency bands. Existing routing proposals help nodes select frequency bands without considering the effect of band switching and intra-bandExpand

Spectrum Aware On-Demand Routing in Cognitive Radio Networks
Routing in multi-hop cognitive radio net- works(CRN) should consider how to dynamically switch frequency band for either per flow throughput guarantee or global spectrum utilization. PreviousExpand

A Cooperative Relay Scheme for Secondary Communication in Cognitive Radio Networks
In cognitive radio networks, secondary users (SUs) opportunistically exploit the spectrum unutilized by primary users (PUs). In this paper, we study the secondary communication where secondaryExpand

A Distributed Sensor Selection Mechanism for Cooperative Spectrum Sensing
In a cognitive sensor network (CSN), selfish sensors can choose to conduct cooperative spectrum sensing (CSS) or local spectrum sensing (LSS). CSS usually improves sensing performance at the price ofExpand
