Path construction using cognitive radio sensing in wireless sensor network

Sensors are widely in use because of low cost and multi functionality. Cognitive radio is nothing but intelligence in some form. Cognitive radio is a form of wireless communication in which a transceiver can detect the availability of channels. Wireless sensor networks are widely being deployed but some of the challenges that arise in wireless sensor network can be overcome by using cognitive radio abilities. When we integrate wireless sensor network with cognitive radio it becomes cognitive radio sensor network.
