  Abstract

Communication technology of future networks is predicted to provide a large variety of services including WiFi service in vehicular network. In this paper, we assume that vehicles are embedded with WiMAX/Wibro antenna and in-vehicle terminals receive WiMAX/Wibro traffic through WiFi interface. This assumption will impose severe performance degradation due to interference among mobile BSSs when WiFi APs are densely located. Existing interference avoidance techniques cannot properly cope with the above problems and resolve dynamically moving vehicular scenario since they focus only on the fixed network topology. In this paper, we propose an intelligent interference avoidance scheme for WiFi services by hopping channels based on periodic competition among BSSs. To measure the effectiveness of the proposed scheme, we evaluated performance by using OPNET simulator. Through the simulation, we obtained 1/800 reduction in the maximum inteference frequency and 300% improvement in throughput.
