Achieving always Best Connected service for a mobile user in VANET

Today, heterogeneous wireless network environments increase more and more. Such environments provide multiple access networks simultaneously for mobile users. Each mobile user wishes to get connected to Internet using the access technology that best suits his needs at any point in time. Always Best Connected is considered as a special concept for mobile users to select their suitable access networks. This article presents a mathematical model to provide, for a smart vehicle moving in a road network, an always best connected service at any point in time using multiple access technologies installed along the road edges. We propose a graph model to characterize the observed mobility pattern, so Dijkstra´s algorithm is proposed to find the optimal path that provides always best connected service.
