In this developed work, nodes are considered from vehicles and transmission capabilities are outfitted with its interconnected vehicles forming a network. Roadside equipment is fixed as all vehicles nearby are equipped with fixed equipment thus enabled communications in real-life application of VANET. In existing methodologies, designs of mobility are required by VANET specifically from Vertical Hand Over decision approach. This fails as of failure in links in networks on focusing issues. Thus, in dissemination of networks, routing is mandatory. Hence, our designed work of Effective two-layer cluster based Routing Mechanism is implemented in VANET to diminish the problems of failures in link. So, hybrid model is incorporated with Biogeography-Based Optimization (BBO) for choosing best available network done and process of vertical handover are done by ant colony optimization. Specific node for vertical handover is chosen based on the weight value from the hybrid model and deploys the SVM classification. On unsteady shape of topology, Effective Two-Level Cluster-based Routing Mechanism is used for maintenance of route. Initially, two clusters are formed with both links as strong and weak from divided nodes to perform routing among cluster members and the best route is chosen by greedy algorithm. High packet delivery ratio and low end to end delay is attained in this proposed approach from the analyzed results against existing methods.

I. INTRODUCTION One of the ensuring and securing technology is Vehicular Ad hoc Networks (VANETs) and allocated with the pool of several mobile nodes with self-configured while unique nodes plays router role intended for relay nodes with multi-hop. To realize more secure and convenient transportation system, VANETs facilitate smart vehicles to exchange wireless messages between themselves [1].

India. assistance, traffic flow conditions and parking or gas station accessibility are included in these messages [2].Vehicles furnished with wireless interfaces are capable of offering ITS services like navigation of vehicle, cloud computing with mobile vehicular, monitor of traffic along with nearby information services which is made possible by the development of intelligent vehicle and new generation wireless communication systems. The applications h framework of have base fact of entire traffic system of traffic connected and facilitated by means of VANETs for communication of nodes in the vehicles. In order to deliver a trustworthy service, several existing challenges in VANET must be looked up [3]. Routing algorithms, security and network architecture are those challenges. In VANET, steady and consistent routing is one of the chief issues, because of the changeable infrastructure and high mobility. Vehicular communications in VANET are categorized in to two major divisions as Vehicle-to-Vehicle (V2V) and Vehicle to Roadside (V2R) [4]. Comparing with V2R based VANETs, V2V-based VANETs are superior with quite a lot of benefits as mentioned below: 1) Primarily, V2V-based VANET is predominantly appealing for majority of the expanding and enhancing countries and distant areas while inaccessible infrastructures of roadside are present, since this kind of VANET is more adaptable and much more unrelated to the roadside conditions [5]. 2) Next aspect is that, since more expensive equipment is not needed, unlike V2R-based VANET, the V2V-based VANET is inexpensive. 3) Subsequently, tiny time of connectivity, fast fading and elevated hand-offs affected frequently by elevated speed relative in distinction of fast-moving vehicles and road-side stations prevented by V2V-based VANET [6]. 4) Conclusively, for vehicle-related functions where in adjacent vehicles exchange messages, the V2V-based VANET is much more suitable. Two major problems in VANET are concerned deeply in this research work. Because of the extreme vehicle speed and continuously altered network topology, uninterrupted connectivity is a major challenging task and since the mobile nodes in the network are dynamic in nature, there comes the play of link failure issue [7].
