Investigation into the operation and Implementation of Mobile IP

IP mobility is very important due to the huge number of terminals that will be mobile in the near future. Historically, IP protocols were designed for stationary terminals. However, the increasing demand on wireless devices offering IP connectivity, such as PDAYsh, andhelds and digital cellular phones, and the tendency of being connected to the internet any time any where becomes a major driver influences the IP technology towards the IP mobility. Principally the mobility support for Internet devices is possible and standardized for both IP protocol version, IPv4 and IPv6 but due to the enhanced functionality and later design of IPv6 some feature concerning the mobility support have been integrated more efficiently in Mobile IPv6 compared to Mobile IPv4. The Architecture of Mobile IP is consists of: Mobile Node, Home Agent, Foreign Agent, Care-of-address (COA), and last but not least, Correspondent node. Mobile IP working involved: Discovering COA, Registering COA and Tunnelling COA Mechanism. Mobile IP has some issues: Routing Inefficiencies, Security Issues, Ingress Filtering, User Perception of Reliability, issues in addressing, slow growth in the wireless LAN Market and competition from other protocols. Solutions to IP mobility stem from the nature of the layers of the IP network but Mobile IP seems to be the most appropriate solution to IP mobilitySchool of Computing, Communications and Electronic
