Requirements for localised IP mobility management

چکیده
Standard IP mobility management (IP-MM) commonly known as Mobile IP, presents a set of technical challenges in performance and scalability, as the mobile host (MN) varies the handoff rate, due to its mobility pattern, between successive wireless points of attachment; these manifest themselves primarily as increased signalling between the MN and its peers. In addition, they encompass sources of latency external to the mobility protocol; a significant component of this latency is induced by signalling round trip time between the communicating entities while in transit. Recently, Mobile IP has been extended by certain micromobility protocol mechanisms, aiming to alleviate the above performance limitations; they are identified as hierarchical/regional or more generically localised IP mobility management. This paper presents an investigation on requirements for IP localised mobility management (IP-LMM). Based on generic principles derived from the effect of localising mobility control signalling it explores the requirement space essential for robust micro-mobility protocol extensions to base IP mobility models.

Performance issues for localised IP mobility management
Base IP mobility presents performance limitations when the mobile host increases its handoff rate between successive wireless points of attachment as a result of its mobility pattern. These limitations are augmented when latency externalities such as the round trip time between the MN and its peers, add to the total of latency and signalling overhead, impeding the performance of the mobility fu...

متن کاملAdvanced IPv6 mobility management for next generation wireless access networks
The theme of this thesis is the advancement of IP mobility management mechanisms to support robustly the delay requirements of interactive IP applications services. Current IPv6 mobility management standards are heavily dependent on reactive manipulations of the IP handoff process. Such modus operandi appears to be insufficient to address delay transparency during interactive IP communications....
متن کاملMobility label based network: Hierarchical mobility management and packet forwarding architecture
Scalability of the network layer mobility management solution is one of the most important requirements for the mobility control plane. Mobility Label Based Network (MLBN) is a new approach to the network layer mobility management problem that relies solely on MPLS to provide both macroand micro-mobility for IPv4 and IPv6 mobile hosts and routers. This new approach does not rely on the existing...
