A Comprehensive Study of Requirements for Network Applications and Routing Protocols Providing Resources in Vehicular Adhoc Networks

Vehicular adhoc networks are special form of Mobile adhoc networks which have more dynamic topology than MANETs but the nodes move in a preordered fashion. Due to the high mobility and complex dynamics in real vehiclular traffic flow, reliable streaming of data over Vehicular adhoc networks is a challenging task as compared to the other general mobile adhoc networks. This paper gives an overview of traffic classification system , resource requirements of applications and efficacy of the routing protocols viz a viz the protocols which help in improving Quality of Service (QoS) of those applications when running on vehicular adhoc networks. This paper throws light on various requirements of applications in terms of QoS metrics and meeting them in an infrastructreless scenario i.e adhoc networks with the help of various routing protocols. VANETs are going to be an important communication infrastructure in our life. Because of high mobility and frequent link disconnections, it becomes quite challenging to establish a robust multi path that helps packet delivery from the source to the destination.
