This study improves the neighbor discovery in VANETs and in doing so decreases the network overhead and increases performance AODV routing protocol. Since AODV is a part of reactive routing protocols, if a request is sent from the source, a link would be created to the destination.The neighbor discovery is created through HELLO message. The HELLO message is broadcasted to all nodes at a specific time and this happens through the use hello timer and is calculated by Hello _interval default value, Min Hello_ Interval and Max Hello_Interval multiplied random number. This STUDY aims at sending HELLO message and through considering the various conditions of the nodes (such as Up, Down and In_Repair), place the unsaved information in the routing table. This condition is not considered for the In repair mode because a node might be in repair mode in the ti but may not be in this mode at the ti+1. It might be arranged according to the up mode and this can cause a freshness and closer path. In...
