An Analytical Analysis of Neighbour and Isolated Node for Geocast Routing in VANET
Geocasting is a special variant of multicasting, where data packet or message is transmitted to a predefined geographical location i.e., known as geocast region. The applications of geocasting in VANET are to disseminate information like, collision warning, advertising, alerts message, etc. The topology of VANET changes frequently and rapidly due to the fast movement of vehicles. Therefore, the link time between two neighbouring vehicles exist for a short span of time. This makes delivery of messages to a geocast region most challenging issue in VANET.
