Introduction to Mobility Management Approaches For Mobile IP Networks:
The wireless network needs effectively managing of the mobility for the services of the mobile subscribers. The Mobile Internet Protocol is suggested to get services of the global mobility for the IP networks. The mobility management schemes are being applied to overcome on the signaling traffic during the care of addresses change or CoA. The signaling traffic is considered which are linked with the Mobile Terminals or MT enrolled with the Home Agents or HA. The Home Agents may be the Foreign Agents or FA and the Gateway Foreign Agents or GFA for the registration of signaling or mobility.
The high mobility Mobile Terminals follows the registration process of the Foreign Agents and Gateway Foreign Agents to be localized by the Hierarchical mobile internet protocol or HMIP and Dynamic hierarchical mobile internet protocol or DHMIP schemes to get the high mobility signaling. The registration process can be reduced in GFA by the Multicast HMIP scheme. The Multicast HMIP scheme provides the less mobility signaling trouble unlike in HMIP and DHMIP strategies. But the Multicast HMIP is more resource taking which leads to high cost. The Proposed project focused on the evaluation on the mean signaling delay and the mean bandwidth for any call in the mobile terminal. The project observes that the MHMIP has more performance as compared to the DHMIP and MIP schemes. The project has focused on the analytical model approach which evaluates the Mobility Management Scheme performance.
The Existing System
The Existing system focuses on the reduction of the location details for the Home Agents and the Signaling latency or dormancy while the MT shifts from one location to other location. The mobility scheme considers the FA and GFA to be systematically arranged into a hierarchical system. The MT updates the FA in a similar regional or local network when it considers the care of addresses or CoA with registering the GFA. The shifting of the MT to other local area or network is followed by the registration of HA by the popular CoA of the GFA. The routing of the packets by the linking of HA which is shifted to the new GFA that is known MT. The GFA first verifies the visitor register and then carry out the packets transfer to the FA of the MT. The registration may get fail if the GFA not works in centralized system architecture. The high traffic signaling on the GFA and its subsequent mobility within the local networks can deteriorate the mobility performance.
The Proposed System
The Proposed System focuses on the approach of Dynamic Location Management for the Mobile Internet Protocol to ease the signaling process in inter regional networks. The project has two IP, the Hierarchical Distributed Dynamic Mobile IP or HDDMIP and the Dynamic Hierarchical Mobile IP or DHMIP. The HDDMIP has the FA to be considered as the FA or GFA as per the mobility. The traffic has been distributed or separated in the regional networks to the required FA. The FA which are linked to the GFA has to be adjusted for every MT. Like this the regional network surrounding becomes separate for the MT. The number of the FA linked to GFA then calculated as the MT mobility criteria’s and the incoming packets rate. The number can be adjustable for each time as per the differentiation in the mobility and the incoming packet rate.
