Abstract

–Amount of Internet traffic has increased significantly in recent times. Penetration of mobile and handheld devices in the society is also remarkable. In order to address the user demands and seamless mobility in IP networks like the Internet, there is a need to have efficient mobility management protocols and architectures. This is required to address various issues that arise due to users’ mobility. Such protocols and architectures should intend to provide better service quality to the end users. Protocols like Mobile IPv6 (MIPv6), Hierarchical MIPv6 (HMIPv6) and Proxy Mobile IPv6 (PMIPv6) have been established as widely accepted mobility solutions for IP based wireless networks which has also been standardized by the Internet Engineering Task Force (IETF). Three Layer MIPv6 (TLMIPv6) strives to provide seamless mobility management under mobile environment. In this paper, MIPv6, HMIPv6, PMIPv6 and TLMIPv6 are thoroughly surveyed. These protocols are also examined under different mobility models to evaluate respective performances. Three mobility models: (1) Random Walk Mobility Model, (2) Probabilistic Random Walk Mobility Model and (3) GaussMarkov Mobility Model are exploited to model the mobility of users, in order to analyze the performance of the protocols. Future scope of the work has also been outlined.
