Handoff occurs when a mobile node moves from one network to another. Mobility management enables network to locate roaming nodes in order to deliver packets and maintain connections with them when moving into new domains. Mobile IPv6 is mainly introduced for the purpose of mobility. Later a newer version of IP called the IPv6 was proposed. It is one of the dominant protocols relevant to wireless network. The first major version of IP is the Internet Protocol version 4 (IPv4). IP is responsible for routing packets across network. One of the most important challenges in mobile Internet Protocol ( IP) is to provide service for a mobile node to maintain its connectivity to network when it moves from one domain to another. Jayaraj, Maria Nadine Simonel Issac, Biju Haldar, Manas Kumar They act as gatewaysĪnalysis of Handoff Mechanisms in Mobile IP Essential for implementing this network are the dynamic mobile IP routers. In this network all nodes are mobile and globally and locally reachable under the same IP address. This paper describes a concept combining mobile IP and ad hoc routing to create a robust mobile network. We then present performance results for Mobile IPv4, route optimization and Mobile IPv6.ĭynamic Mobile IP routers in ad hoc networks The paper presents some architectural and mobility management options for integrating wireless access to the Internet. This paper addresses the problem of mobility management, i.e., that of tracking the current IP addresses of mobile terminals and sustaining active IP connections as mobiles move. Many issues introduced by the mobility of users arise when such an integration is attempted. There is an emerging interest in integrating mobile wireless communication with the Internet based on the Ipv6 technology.
