Abstract

Vehicular Ad Hoc Network (VANET) is an instance of MANETs that establishes wireless connections between vehicles. Recently, it was shown for the case of highway traffic that position-based routing protocols can very well deal with the high mobility of network vehicles. In VANETs, these routing protocols must be adapted to vehicular-specific capabilities and requirements. As many previous works have shown, routing performance is greatly dependent on the availability and stability of wireless links. This work adapts the Location-Aided Routing protocol for inter-vehicle communications in a highway environment. We improved the stability of routes between sources and destinations, by forwarding the route request message to the neighbor which stays the longest time in communication range of the forwarder, and avoiding the nodes moving in opposite direction of source movement to participate in research of route if there are the nodes traveling in the same direction of the source motion. The performance metrics such as average delay of path stability between source and destination, packet delivery ratio (PDR), throughput, and normalized routing load (NRL) are measured using ns2. The Intelligent Driver Model with Lane Changing (IDM_LC) based on VanetMobiSim tool is used to generate realistic mobility traces in highway.
