Comparison of Survivability & Fault Tolerance of Different MIP Standards

Mobile IP, the current method of internet connectivity is most often found in WLAN environments where users need to carry their mobile devices across multiple LANs with different IP address. This project work first surveys existing protocols for supporting IP mobility and then proposes an extension to mobile IP architecture, called Robust Hierarchical Mobile IP version6 (RH-MIPv6). This architecture attempts to achieve smaller handoff latency in intra-domain mobile network. In RH-MIPv6 a mobile node (MN) registers primary (P-RCoA) and secondary (S-RCoA) regional care of address to two different MAPs simultaneously. In adaptation to this a “MOVING AREA BASED MAP SELECTION SCHEME” is proposed in this paper. A mechanism is developed to enable the mobile node or correspondent node to detect the failure of primary MAP and change their attachment from primary to secondary MAP. With this recovery procedure, it is possible to reduce the failure recovery time. In this paper it is shown that RH-MIPv6 has faster recovery time than MIPv4 and HMIPv6.
