Enhanced Safety Message Transmission in High Density Traffic in Urban Region

Parminder Kaur ^[11] | Deepinderjeet Kaur Dhaliwal ^[2]

Abstract: VANET is vehicular Ad-hoc network which is used for intelligent transport system for the drivers the ad-hoc network is used to transmit various types of message over the network. Safety message has to transmit for the security reasons on the vehicle and road transportation various routing protocols have been utilized for the purpose of message transmission. GPRS, AODV, DSR, PUMA these are various routing protocol utilizes for message transmission VANET scenario is used for mainly V2V and V2R purposes. The main issue in road density is high load because of this road message communication get overhead and due to less amount of network bandwidth to overcome this issue cognitive radio bandwidth can be utilize for data transmission by using channel sensing and message can be transmit through cognitive radio channels.
