Application-aware handover with minimal power consumption for multimedia streaming service in wireless LAN

ABSTRACT

It is a challenging task to provide handover with guaranteed QoS for real-time multimedia service such as VoIP, video/audio streaming, and video conferencing in wireless LAN. This paper is aimed at presenting efficient layer 2 handover mechanism in wireless LAN, which can provide fast handover with guaranteed QoS for real-time multimedia service. In order to meet the above objective, the scanning period and the number of channels per scanning for handover are dynamically adapted to the types of applications and wireless networking environment, so that both the degradation of application service quality and signaling overhead are minimized simultaneously. We simulate proposed mechanism to verify the performance. The simulation results show that the proposed mechanism avoid service quality degradation and provide session connectivity.
