Effective Routing and Spectrum Sensing in Energy Efficient Cognitive Radio Based Vehicular Ad-Hoc Network

Vehicular Ad Hoc Network (VANET) is one among the trending technology to perform intelligent transportation to control the road accident and traffic congestion. To perform that effectively in high speed VANETs, Cognitive radio (CR) is integrated with it. Currently to achieve better data transmission with high-speed movements-based vehicles routing and spectrum scarcity need to get concentrated. This paper proposed Effective Routing and Spectrum Sensing in Energy Efficient (ERSCR) CR-VANETs to attain effective routing. The process is categorized into three sections, they are effective routing in CR-VANETs, and cluster based optimal channel section and Spectrum sensing using spatial and temporal correlation process. The effective routing which is used in this method helps to reduce the delay and congestion in the network. Through cluster based optimal channel section process the high speed vehicles are properly monitored so that unnecessary packet loss and link failures are avoided. Through spectrum sensing the source can able to find its destination in a brilliant manner with any traffic congestion occurrences. Through this method route's stability is improved that leads to provide a way for successful data transmission. The simulations performed in NS2 with SUMO show that the proposed ERSCR-VANETs attain promising results on packet delivery ratio, throughput, end to end delay and routing overhead when compared with the earlier researches like MOOCR-VANET and CMHCR-VANET.
