Natural disasters, such as earthquakes, can cause severe destruction and create havoc in
the society. Buildings and other structures may collapse during disaster incidents causing …

In cognitive radio networks (CRNs), two secondary users (SUs) need to meet on a channel
among multiple channels within a finite time to establish a link, which is called rendezvous …

With the rapid increase of the wireless applications, the cognitive radio network as a
promising solution has attracted a lot of researches in recent years. One of the critical issues …

In channel-hopping (CH)-based distributed cognitive radio networks (CRNs), the time
duration that secondary users (SUs) spend for establishing communication links is called …

To improve wireless spectrum utilization, cognitive radio networks (CRNs) allow secondary
users (SUs) opportunistic access to the frequency bands owned by primary users (PUs) …

Based on the standards for wireless sensor system identification, the sensor node identity
OID identification and the management object OID identification in the SNMP MIB are …

Spectrum sensing has a very important role in the operation of cognitive radio network. A
proper sensing and utilization improve the performance of cognitive radio network (CRN) …

We design two estimation schemes, Method I and Method II, for rapidly obtaining separate
estimates of the number of active nodes of each traffic type in a heterogeneous machine-to …

As the data traffic is increasing, the spectrum bands are getting congested. It causes low
latency and unreliable communication. Additional spectrum can be utilized to solve this …

Cognitive radio (CR) is an auspicious technique that can help to address growing demand
for spectrum in six-generation communication devices. CR uses concept of opportunistic …
