Currently, the radio spectrum is statically allocated and divided between licensed and
unlicensed frequencies. Due to this inflexible policy, some frequency bands are growing in …

The Cognitive Radio and the Cognitive Radio Networks have recently become one of the
most intensively studied paradigms in wireless communications. The main distinctive …

Cognitive radio networks have been recognized as a promising paradigm to address the
spectrum under-utilization problem. To improve spectrum efficiency, many operations such …

Cognitive radio networks (CRNs) have emerged as advanced and promising paradigm to

Proactive based RPL is the network layer routing protocol designed for route-discovery to
transmit the constrained application data from leaf nodes (LLN) to the LLN boarder router …

Rendezvous is a fundamental and essential operation for users of cognitive radio networks
(CRNs) to meet and establish a link on a common channel, so that information exchange …

We investigate the state estimation problem in cyber-physical systems (CPS) where the
dynamical physical process is measured by a wireless sensor and the measurements are …

Rendezvous is a fundamental operation in cognitive radio networks (CRNs) for establishing
a communication link on a commonly-available channel between cognitive users. The …

Implementation of any cognitive radio network requires an effective control channel that can
operate under various modes of activity from the primary users. This paper reports the …
