Abstract: Vehicular ad hoc networks (VANETs) are mobile wireless networks which are designed to support public safety by traffic tracking. In VANETs, vehicle mobility will cause the communication links between vehicles leads to broken. Such link failures responsible for excessive increase in the routing overhead and degradation in network scalability. In this paper, we propose dynamic time scalable hybrid protocol which combines features of reactive routing with geographic routing to address this issue. A dynamic time scalable hybrid location- based ad hoc routing (HLAR) protocol is used for reducing routing overhead and degradation in network scalability by using available location information. As the location information degrades hybrid protocol is designed in such a manner that it can be exit to reactive routing.
