Survey of Mobile IP Protocols

Abstract

In recent years, for protecting Mobile Internet Protocol, considerable researches have been made to develop various security protocols. In order to fully understand the security implications of the design constraints, it is necessary to briefly analyze the existing works on providing security in Mobile IP network. Moreover, there is no combined survey of handoff, routing, and security mechanisms in Mobile IP networks. In this paper, we present a detailed investigation of current state-of-the-art Mobile IP protocols in Mobile IP networks. Initially, the existing works on routing and handoff are discussed. After that, the existing security mechanisms are analyzed by categorizing the security mechanisms as security on route optimization and security during handoff. A brief outline of the key concept, metrics used, as well as the advantages and drawbacks of each discussed mechanism are given. Finally, the comparison table is constructed to summarize several mechanisms.
