In cognitive radio networks, spectrum sensing is a crucial component in the discovery of
spectrum opportunities for secondary systems (or unlicensed systems). The performance of …

In this paper, we propose a novel architecture for optimizing the overall performance of
vehicular dynamic spectrum access (VDSA) networks. Due to the high level of mobility for …

In cooperative spectrum sensing (CSS), a multibit combination rule shows better sensing
performance than one-bit hard combination rules at the sacrifice of the reporting overhead …

Cooperative spectrum sensing (CSS) has been proposed to improve the reliability of
decisions made about the presence of primary users in cognitive radio networks. However …

We overview the challenges related to spectrum awareness in the vehicular environment,
with emphasis on awareness in the TV licensed band. In the vehicular environment the …

Cooperative spectrum sensing is an effective technique to improve the sensing performance
and increase the spectrum efficiency in cognitive radio networks (CRNs). In this paper, we …

Currently, a dedicated frequency band is assigned to each of a number of wireless
technologies, artificially causing spectrum shortage for new services. It is expected that …

In cognitive vehicular networks, unlicensed secondary users heavily depend on spectrum
sensing to find unused spectrum bands for communications. The performance study of …

It is well known that broadband wireless communications (BWC) are necessary for high
speed vehicles since passengers need many broadband wireless multimedia services …

Integral and crucial to performance of wireless sensor networks (WSNs), and specifically
industrial wireless sensor network (IWSN) is stable, robust, reliable, and ubiquitous …
