Network selection in an environment of heterogeneous wireless networks (HWNs) has been widely studied, but mobility-related factors were not well considered by selection schemes in the literature. Since vertical handover (VHO) corresponds to permutation of networks, the selection of a network actually becomes the selection of a permutation when VHO properties are considered. In this paper, we propose a best permutation scheme (Basic Besper) for mobility-based network selection in a generic HWN environment and two methods (i.e. Simplified Besper and Enhanced Besper) to further improve the time complexity of Basic Besper. According to our performance evaluations, Bespers could always select the best network and permutation based on mobility-related factors and many advantages compared with classic best network schemes are demonstrated. Furthermore, the two methods (especially Enhanced Besper) could find the best network quite rapidly, which is important for the continuity of real-time applications during VHOs.
