With financial, business and personal transactions shifting to the mobile domain, Mobile Computing and Wireless Communication technologies are on focus. One of the major challenge is to provide best connectivity across heterogeneous networks, in fast moving vehicles, without knowledge and disturbance to the user. An Intelligent system is required for seamless vertical handover, with less battery consumption and with best connectivity. The Vertical Handover process can be optimized for different criteria like cost, bandwidth, signal strength etc. This paper aims to develop a best solution framework for VHO in vehicular networks where OMNeT++ (Objective Modular Network Testbed in C++) can be used for evaluating and testing along with Veins (Vehicles in Network Simulation) software for the simulation of Inter-Vehicular Communication (IVC) framework, which is composed of an event-based network simulator and a road traffic micro simulation model.
