Review On A Reliability-based Routing Protocol for Vehicular Ad-Hoc Network

Vehicular ad hoc networks (VANETs) are a special form of wireless networks which is made by vehicles communicating among themselves on roads. The conventional routing protocols proposed for mobile ad hoc networks (MANETs) are not suitable they work poorly in VANETs. As communication links break more frequently in VANETs than in MANETs, the routing reliability of such highly dynamic networks needs to be paid special attention. A very little research has focused on the routing reliability of VANETs on highways. In this paper, we use the evolving graph theory to model the VANET communication graph on a highway. The extended evolving graph helps us to capture the evolving characteristics of the vehicular network topology and determines the reliable routes preemptively. This paper is to propose an evolving graph-based reliable routing scheme for VANETs to facilitate quality-of-service (QoS) support in the routing process. A new algorithm is developed to find the most reliable route in the VANET evolving graph from the source to the destination
