Performance of Various Mobile IP Protocols and Security Considerations

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