Throughput-efficient sequential channel sensing and probing in cognitive radio networks under sensing errors
In this paper, we exploit channel diversity for opportunistic spectrum access (OSA). Our
approach uses channel quality as a second criterion (along with the idle/busy status of the …

Distributed opportunistic scheduling for ad-hoc communications: An optimal stopping approach
We consider distributed opportunistic scheduling (DOS) in wireless ad-hoc networks, where
many links contend for the same channel using random access. In such networks …

QoS-compliant sequential channel sensing for cognitive radios
In this paper, we study the quality-of-service (QoS) support for realtime traffic in cognitive
radio (CR) networks when spectrum availability and quality is not known a priori. A resource …

Sequential opportunistic spectrum access with imperfect channel sensing
In this paper, we exploit channel diversity for opportunistic spectrum access (OSA). Our
approach uses instantaneous channel quality as a second criterion (along with the idle/busy …

In a dynamic spectrum sharing system, a cognitive radio (CR) is provided with more
channels than what it can use. So it is important for the CR to select the right channels for its …
