This paper provides an overview of cognitive radio (CR) networks, with focus on the recent
advances in resource allocation techniques and the CR networks architectural design. The …

With the advent of multiple radio interfaces on a single device, wireless mesh networks start
to achieve significant improvement in network capacity, latency, and fault tolerance. The …

Are you involved in designing the next generation of wireless networks? With spectrum
becoming an ever scarcer resource, it is critical that new systems utilize all available …

An important issue of supporting multi-user video streaming over wireless networks is how to
optimize the systematic scheduling by intelligently utilizing the available network resources …

Due to such features as low cost, ease of deployment, increased coverage, and enhanced
capacity, multihop wireless networks such as ad hoc networks, mesh networks, and sensor …

The ability of newer generations of commercially available radios used on the sensor nodes
to tune their operating frequency over different channels provides an opportunity to alleviate …

A node can provide a file to other nodes after downloading the file or data from the Internet.
When more than one node have obtained the same file, this is considered a multisource …

The use of multiple channels can substantially improve the performance of wireless mesh
networks. Considering that the IEEE PHY specification permits the simultaneous operation …

Optimal capacity analysis in multi-radio multi-channel wireless networks by nature incurs the
formulation of a mixed integer programming, which is NP-hard in general. The current state …

In this paper, we investigate the problem of multiuser resource management in multihop
cognitive radio networks for delay-sensitive applications. Since tolerable delay does not …
