Abstract The Wireless Access in Vehicular Environments (WAVE) protocol stack has been
recently defined to enable vehicular communication on the Dedicated Short Range …

The increasing demand of diverse vehicular network oriented applications (both safety and
non-safety related services would undoubtedly lead to shortage of spectral resource …

To solve the contradiction between the increasing demand of diverse vehicular wireless
applications and the shortage of spectrum resource, a novel cognitive cooperative vehicular …

In congested areas, enough spectrum is needed to transmit safety and non-safety
messages. Spectrum Sensing with Distributed TDMA (SSD-TDMA) accesses the channel in …

The highly anticipated era of vehicular communication networks which is also an integral
aspect of Intelligent Transportation Systems (ITS) will undeniably improve transport safety …

Presently, the world of wireless communication is going under some crucial challenges,
which attracts the attention of several researchers. Cognitive radio is defined as a …

In this thesis we have considered a cognitive radio network (CRN) with a pair of primary user
(PU) and secondary user (SU) in spectrum sharing networks in path-loss and without path …
