Framework for network selection transparency on vehicular networks

The advanced wireless technologies make vehicle-to-vehicle communication possible. However, vehicular network has a limitation in terms of network topology rapidly change, which causes discontinuous connection. To support seamless connection, horizontal and vertical handovers are required. The good handover mechanism should take network parameters, user requirements, and application QoS into account. Thus, this paper proposes the framework for network selection mechanism to guarantee application QoS. This framework will be applicable to Communications Access for Land Mobiles (CALM) standard. However, CALM suggests only generic framework without specific implementation. This framework proposes internal structure, implementation and decision methodology for network selection module. The network selection mechanism is based on the knowledge of real-time network performance, application QoS and user requirements.
