Abstract

Next generation wireless networks environment (4G) could provide the users with free moving experience and desirable quality of services among heterogeneous networks. Thus vertical handoff is one of the most important issues. The existing vertical handoff decision algorithms are usually designed for low speed cases, which are not suitable when terminals move fast across several networks covering scales. To resolve this problem, we propose a novel speed sensitive vertical handoff algorithm based on fuzzy control. Based on collected information on RSS, load conditions of candidate networks, velocity of mobile terminals and user preference, the vertical handover decision is made by fuzzy logic process. It improves the handoff efficiency when users are moving at a high speed. Simulation results show that the proposed algorithm can reduce unnecessary vertical handoffs caused by high speed.
