Vehicular ad-hoc network is a sub class of mobile ad-hoc network (MANET) with a difference of having moving vehicles as nodes. Todays, it is growing very fast. ITS have two key components self-organized and key component for VANETs. In Vehicular ad hoc network (VANET) vehicles can share data and communicate without infrastructure with other vehicles and road side units (RSU). These networks are having highly dynamic topology with fast moving vehicles and frequent disconnection properties. It requires handover management and an efficient routing algorithm. This research paper contains a network which is the combination of vehicular nodes, road side unit (RSU), and WiMax. This paper also proposed an optimized routing algorithm for handover management in VANET. This algorithm is compared with RBRA. The paper results that the proposed algorithm has minimum transmission time and minimum request block rate.
