Abstract
Cognitive radio technology is an inventive method to solve spectrum scarcity problems in wireless networks. Growing interest of cognitive radio (CR) technology in vehicular communication systems has led CR-enabled vehicular ad hoc network (CR-VANET). It allows the efficient use of radio frequency spectrum. In vehicular ad hoc networks (VANETs), mobility of nodes leads to frequent changes of network topology making routing a challenging task. It is important to balance different parameters such as impact of spectrum availability, dynamic nature of VANET, varying interference and security while designing solutions for CR-VANETs. In this paper, we have compared AODV and DSR routing protocols in CR-VANET scenario and have found that AODV protocol is more suitable. It is observed that on-demand routing protocols outperform reactive protocols. All the experimental work is conducted through OPNET network simulator.
