—Most previous research on multiprotocol label switching (MPLS)/generalized MPLS (GMPLS) recovery management has focused on efficient routing or signaling methods from single failures. However, multiple simultaneous failures may occur in large-scale complex virtual paths of MPLS/GMPLS networks. In this paper, we present a dynamic MPLS/GMPLS path management(More)
In this paper, we present an adaptive handover method with application-awareness for multimedia streaming service in wireless local area networks. Traditionally, the handover method in wireless local area network did not take into account the characteristics of the application service. Thus, the severe service disruption may occur during the movement of(More)
With the rapid growth in specialized biomedical sensors, wireless communication and low power integrated circuits; the wireless sensor network has achieved a new milestone. IEEE 802.15.4 standard uses carrier sense multiple access with collision avoidance (CSMA-CA) medium access mechanism and supports star as well as peer-to-peer topologies. By using(More)
—The IEEE has recently started to develop a standard for the wireless body area network (WBAN). Providing high mobility with guaranteed QoS over the u-healthcare network which are built from the converged WBAN and WLAN systems is a challenging task. This article proposes a context-aware mobility management framework which can support high mobility in the(More)
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(More)
