In the future cloud computing, users will heavily use mobile devices. Mobile networks for cloud computing should be managed efficiently as well as support seamless services to mobile users regardless of their locations and movements. Hence, in mobile networks for cloud computing, it is important to support seamless mobility management to mobile users who(More)
NEMO accelerates the handover procedure through tunneling, it may cause a serious burden of the tunnel between Mobile Access Gateways (MAGs). This is because all packets destined for Mobile Network Nodes (MNNs) are forwarded to a New MAG (NMAG) through the tunnel between MAGs. This problem becomes more critical, as the number of MNNs is large and there(More)
—To maintain the Internet connectivity of a group of nodes in intelligent transportation systems (ITSs), the network mobility basic support (NEMO BS) protocol was standardized. The NEMO BS provides mobility for mobile network nodes (MNNs) in a moving network through a mobile router (MR). Since packet loss in NEMO dramatically increases during a handover as(More)
The IEEE 802.16e standard enhances the IEEE 802.16 for the mobility support. Mobile stations can move while receiving services, thus ongoing IP sessions may be maintained during a handover in the IEEE 802.16e. To reduce handover latency, the idea of cross-layer handover which incorporates layer 2 handover with IP layer has been devised. Various cross-layer(More)
