The comparison between TCP and UDP tunnels have not been sufficiently reported in the
scientific literature. In this work, we use OpenVPN as a platform to demonstrate the …

Nowadays, GPS-based car navigation systems mainly use speech and aerial views of
simplified road maps to guide drivers to their destination. However, drivers often experience …

The idea of Cognitive Radio (CR) is to share the spectrum between a user called primary,
and a user called secondary. Dynamic Spectrum Access (DSA) is a new spectrum sharing …

The concept of Cognitive Radio (CR) has emerged as a practical solution to solve the issue
of the fixed spectrum and bandwidth scarcity in wireless communication. However, the …

Cognitive Radio (CR) networks allow users to opportunistically transmit in the licensed
spectrum bands, as long as the performance of the Primary Users (PUs) of the band is not …

Performance evaluation of transport layer protocols in cognitive radio sensor networks
(CRSNs) is useful to provide quality-of-service for real-time reliable applications. This paper …

Communication requirements for cognitive radio sensor networks (CRSN) necessitate
addressing the problems posed by dynamic spectrum access (DSA) in an inherently …

In this paper, we investigate the problem of robust congestion control in infrastructure-based
cognitive radio networks (CRN). We develop an active queue management algorithm …

Cognitive radio technology has been used to efficiently utilize the spectrum in wireless
networks. Although many research studies have been done recently in the area of cognitive …

Reliable and high throughput data delivery in cognitive radio networks remains an open
challenge owing to the inability of the source to quickly identify and react to changes in …
