A New Geocast Routing Protocol for VANETs

Efficient routing in the vehicular Ad hoc networks (VANET) is a crucial issue, especially in the recent years due to advances in technology and car industry. VANET’s rapidly changing topology and high speed of nodes makes routing challenging. Geocast routing is a sub-category of location based routing where the destination of the data is any node in a geographical area. First, we study some works done in this category with different approaches and then we present a new geocast routing protocol without the use of beacon messages where forward progress to the destination, intersection awareness and location prediction are taken into account.
