Mobile IP, Mobility Management, Time Delay, Agent, Bandwidth

Mobile IP is the underlying technology for support of various mobile data and wireless networking applications. Mobile IP can be thought of as the cooperation of three major subsystems. First , there is a discovery mechanism defined so that mobile computers can determine their new attachment points (new IP addresses) as they move from place to place within the internet. Second , once the mobile computer knows the IP address at its new attachment point , it registers with an agent representing it at its home network. Lastly , Mobile IP defines simple mechanisms to deliver datagram’s to the mobile node when its is away from its home network. This work focuses on parameters based comparison for different mobile IP protocols. Parameters include Bandwidth , Time Delay and file size. An analytic model is adopted to propose for evaluating the mean signaling delay and the mean bandwidth per call according to the type of MT mobility. In this analysis, the MHMIP outperforms the DHMIP and MIP strategies in almost all the studied cases. The main contribution of this paper is the analytic model that allows the mobility management performance evaluation and basic security implementations on Agents. In future, Maintaining most computers on a private network, visible to the public Internet necessitated with highly secured environment.
