Combinatorial Mobile IP, a new mobility management scheme for Mobile IP, is proposed and analyzed. We present how to adopt mobility management schemes on cellular networks and adapt them in Mobile IP without disrupting the nature of the Internet. We apply widely used mobility management schemes such as hierarchical architecture and paging in cellular networks to Mobile IP. We restrict paging to...

ÐFor a PCS network to effectively deliver services to its mobile users, it must have an efficient way to keep track of the mobile users. The location management fulfills this task through location registration and paging. To reduce the signaling traffic, many schemes such as Local Anchor (LA) scheme, per-user caching scheme and pointer forwarding scheme have been proposed in the past. In this p...

One of the major challenges for the nextgeneration mobile systems is related to efficient mobility management issue. In this paper, we propose a new micromobility management scheme, called Micro Mobile MPLS, that supports both mobility and quality-of-service (QoS) management in wireless networks. Our proposal includes two protocol variants. In the first variant, called FHMicro Mobile MPLS, we c...

For a mobile node that uses both Mobile IP and Session Initiation Protocol (SIP), there is severe redundant registration overhead because the mobile node has to make location registration separately to the Home Agent for Mobile IP and to the Home Registrar for SIP. Therefore, we propose two new IP mobility management methods that integrate both Mobile IP and SIP. Performance comparisons are mad...

Next generation wireless/mobile networks will be IP based cellular networks integrating the internet with cellular networks. In this paper, we propose a new architecture for a high speed transport system and a mobile management protocol for mobile internet users in a transport system. Existing mobility management protocols (MIPv6, HMIPv6) do not consider real world fast moving wireless hosts (e...

With developments in voice over IP (VoIP), IP-based wireless data networks and their application services have received increased attention. While multimedia applications of mobile nodes are served by Session Initiation Protocol (SIP) as a signaling protocol, the mobility of mobile nodes may be supported via Mobile IP protocol. For a mobile node that uses both Mobile IP and SIP, there is a seve...

The Mobile IP Standard has been developed to support mobility over the Internet. This standard contains several drawbacks as in the cases where packets are routed via sub-optimal paths and significant amount of signaling messages is generated due to the home registration procedure which keeps the network aware of the current location of the mobile nodes. Recently, a dynamic hierarchical mobilit...

As the future generation networks are envisioned to be heterogeneous in nature, seamless mobility in such networks is an important issue. While IETF work groups have standardized various mobility management protocols, such as Mobile IPv6 (MIPv6), Fast Handovers for Mobile IPv6 (Predictive FMIPv6, and Reactive FMIPv6), Hierarchical Mobile IPv6 (HMIPv6), Proxy Mobile IPv6 (PMIPv6) and Fast Handov...

In a Personal Communications Services (PCS) network, mobility databases such as Home Location Register (HLR) and Visitor Location Register (VLR) are utilized to support mobility management for Mobile Stations (MSs). If the location databases fail, the location information loss or corruption will seriously degrade the service offered to the subscribers. In this paper, we propose a new VLR failur...
