Mobility-based Network Selection Scheme in Heterogeneous Wireless Networks

Recently, network selection for heterogeneous wireless networks has been widely studied by categorizing and employing various factors to decide the best network. Mobility-related factors can be used to represent mobility features or mobile terminals (MTs) and mobility support capabilities or wireless networks, but they are complicated in usage and are not well used in related works. In this paper, we study the usage of these factors and provide a scheme to use them in the same way as other factors in a network selection framework. By analysis and simulations, we demonstrate that mobility-related factors should be considered in network selection schemes, and our scheme achieves the goal of selecting the most appropriate network for MTs with various mobility features.
