“…CN j checks if more than 50% query or suspect of malicious behavior exist, the IF CNj CVi is set as INFINITY which detects CV i as malicious node and sends warning message to the all the neighboring nodes in the network. Finally, the entry of node CV i is updated in blacklist and the malicious node CV i is discarded from the routing protocols namely OCAS [1], PRACB [6] and DMN [11] considering throughput and end-to-end delay.

“…So efficient utilization of spectrum has resulted in a challenge. To overcome this challenge, CR technology has emerged as a prominent technology which utilize the radio spectrum efficiently in a opportunistic manner [1] and thus improves spectrum efficiency. By providing CRN technology to WSN which prompts to Cognitive Radio Sensor Network (CRSN), WSN nodes capable to get the facilities of the CRNs and will be able to exploit the utilized spectrum intelligently.…”

This paper introduces an efficient reactive routing protocol considering the mobility and the reliability of a node in Cognitive Radio Sensor Networks (CRSNs). The proposed protocol accommodates the dynamic behavior of the spectrum availability and selects a stable transmission path from a source node to the destination. Outlined as a weighted graph problem, the proposed protocol measures the weight for an edge the measuring the mobility patterns of the nodes and channel availability. Furthermore, the mobility pattern of a node is defined in the proposed routing protocol from the viewpoint of distance, speed, direction, and node's reliability. Besides, the spectrum awareness in the proposed protocol is measured over the number of shared common channels and the channel quality. It is anticipated that the proposed protocol shows efficient routing performance by selecting stable and secured paths from source to destination. Simulation is carried out to assess the performance of the protocol where it is witnessed that the proposed routing protocol outperforms existing ones.
