Wireless sensor networks (WSNs) use the unlicensed industrial, scientific, and medical
(ISM) band for transmissions. However, with the increasing usage and demand of these …

The integration of cognitive radios and wireless sensor networks enables a new paradigm of
communication in which, sensor nodes can avoid heavily crowded transmission bands by …

Abstract A Cognitive Radio Sensor Network (CRSN) is a distributed network of sensor
nodes, which senses event signals and collaboratively communicates over dynamically …

Cognitive radio sensor network (CRSN) is a combination of wireless sensor network (WSN)
and opportunistic spectrum access technology. It involves the issues related to energy and …

A cognitive wireless sensor network is considered, where a cluster of secondary sensors
utilize channel vacancies of a primary network and transmit their measurement samples to a …

Cognitive radio sensor networks (CRSNs) employed clustering topology to help sensor
nodes operate autonomously improve energy consumption, provide quality of service …

Packet size optimization is a critical issue in wireless sensor networks (WSNs) for improving
many performance metrics (eg, network lifetime, delay, throughput, and reliability). In WSNs …

In this paper, we propose a simulation model for cognitive radio sensor networks (CRSNs)
which is an attempt to combine the useful properties of wireless sensor networks and …

In this paper, we define a cluster based scheduling algorithm for Cognitive Radio Sensor
Networks. To avoid inter-clusters collision, we assign fixed channels only to nodes having …

This paper highlights three critical aspects of the internet of things (IoTs), namely (1) energy
efficiency,(2) energy balancing and (3) quality of service (QoS) and presents three novel …
