Providing handover with guaranteed QoS for realtime multimedia service such as VoIP, video/audio streaming, and video conferencing in wireless LAN is a challenging task. In this paper, we present a context-aware mobility management mechanism in wireless LAN, which can provide fast handover with guaranteed QoS for real-time multimedia service. To this end, the scanning period and the number of channels per scanning for handover are dynamically adapted to application context, so that both the degradation of application service quality and energy consumption are minimized simultaneously. The performance of the proposed mechanism is verified by the simulation. The simulation results show that the proposed mechanism is useful for the personalized network which is comprised of wireless LANs.
