A Review of Cognitive Radio using Mobile Ad-hoc Network Protocols: Approaches and Challenges

Aparna Singh Kushwah ^[2] | Raksha Thakur

Abstract: With increasing interest in using cognitive radio (CR) technology in wireless communication systems for MANET, it is envisioned that future devices will be CR-enabled. This paper discusses CR technologies using different routing protocols for mobile networks aimed at improving spectrum efficiency. CR for mobile networks has the potential of becoming a killer CR application in the future due to a huge consumer market for mobile communications. This paper surveys novel approaches and discusses research challenges related to the use of cognitive radio technology in mobile ad hoc networks. The review explains how CR technologies such as dynamic spectrum access, adaptive software-defined radios and cooperative sensing will enhance mobile communications using applicable routing protocols such as AODV, DSDV and DSR. After observing their basic principles, their performance and characteristics are evaluated. In addition, several challenges an, d requirements have been identified.
