In cognitive radio networks (CRNs), multiple secondary users may send out requests
simultaneously and one secondary user may send out multiple requests at one time, ie …

Cognitive radio networks (CRNs) are an emerging paradigm for next generation wireless
communication systems allowing for more efficient radio spectrum utilization. In order to …

With the diversification of Internet services and the increase in mobile users, efficient
management of network resources has become an extremely important issue in the field of …

Bandwidth management and traffic control are critical issues to guarantee the quality of
service in cognitive radio networks. This paper exploits a network load refinement approach …

Multimedia applications have been becoming a majority type of traffic over cognitive radio
network (CRN). Considering the different delay requirements of heterogeneous multimedia …

This paper studies the service time required to transmit a packet in an opportunistic
spectrum access scenario, where an unlicensed secondary user (SU) transmits a packet …

The equilibrium joining probabilities for a single primary user (PU) and secondary users
(SUs) in the case of no queue length information, and the equilibrium Nash balance …

In the cognitive radio network (CRN), secondary users (SUs) compete for limited spectrum
resources, so the spectrum access process of SUs can be regarded as a non-cooperative …

Cellular communication networks are plagued with redundant capacity, which results in low
utilization and cost-effectiveness of network capital investments. The redundant capacity can …

A vast body of literature usually has treated cognitive radio (CR) networks as single-band
queues with preemptive priority for mathematical tractability, although, in practice, they are …
