To support highly flexible network mobility in mobile communication systems, various types of movable network entities, especially mobile base stations (M-BSs), will appear in near future. In this environment, a scanning process to identify the availability of neighbor M-BSs for handoff should be newly designed, because a conventional method does not reflect the motion of base stations. Therefore, we propose an efficient scanning algorithm based on the concept of sample vectors and comparison metrics for estimating the relative motion of a serving M-BS and a user. By using the proposed algorithm, the user can avoid unnecessary scanning trials for the neighbor M-BSs that are moving away from the user and simulation results show a substantial performance gain with respect to the interruption time caused by the scanning process.
