Multi-agent schema of Mobile IP protocol for mobile environment

Mobile communication has been more and more popular not only because it supports convenient wireless communication within networks but also due to the powerful roaming function among networks without disconnection. In conventional mobile communication designs, there is usually only one single Mobile Agent (MA) in one network, which means the whole network would go out of control once MA fails in the network Another drawback is that each MA and node in the network should maintain the binding information in its own cache. However, ask every node to store and maintain the binding information in its cache is a heavy burden. In this study, the proposed Fault-tolerant Multi-agent based Mobile IP (FMIP) schema, which can solve the above drawbacks of single MA in one network by using the multi-agent based model to provide fault-tolerant capability. In addition, we also solve the drawback of each node should maintain the binding information in its own cache by maintaining the Mobile Agent Table (MAT) and Binding Update Table (BUT) in the MA only. Finally, we shall also provide the Smooth Handoff mechanism, Take Over mechanism, and Recovery mechanism for the mobile environment to provide the powerful fault-tolerant capability.
