With the rapid growth of wireless communication technologies and mobile applications, more and more mobile terminals need to access Internet seamlessly. Due to the IP address acts as both identifier and locator for a mobile terminal, it cannot guarantee the service continuity when a mobile terminal keeps moving. An efficient mobility management schemes for a mobile terminal is important. The Host...
At present, the number of Internet subscribers accessing Internet through mobility terminal equipment and other new types is gradually increasing, which shows it's important to develop mobility management protocols in order to provide mobility support for the subscribers. Several protocols were proposed to support IP mobility in the IETF, such as MIPv6, HMIPv6, FMIPv6 and F-HMIPv6. Some performance...
With the best-effort TCP transporting foreground traffic, below-best-effort transport protocols are developed to transport background traffic. However, we argue in this paper that: 1) two fixed levels of priority are not enough, and 2) the background and foreground transfers are subjective concepts which can only be decided by users but not arbitrarily determined by the network according to the application...
In mobile IP and its fast handover protocol, mobile node needs to configure temporal IP address after handed over from one access router to another. Movement detection, router discovery and duplicate address detection are procedures needed in the handover. We study the impact of those procedures on IP handover latency in this paper. Several methods to accelerate those procedures are investigated,...
Mobile IPv6 (MIPv6) is a generally accepted mobility management protocol to support user mobility in IP networks, which use registration mechanism to maintain location information of mobile nodes. However, MIPv6 can not satisfy requirements of seamless mobility, such as signaling traffic, handoff delay and packet loss rate. Accordingly, there are two typical location management extensions to MIPv6:...
