Handoff mechanism in Mobile IP

Abstract

Among the characteristics of the future wireless networks is the desire to support a wide range of wireless users and a diverse set of services from many different types of networks. A unifying technology for diverse wireless networking is Mobile IP, a protocol established by the Internet Engineering Task Force (IETF) that allows mobile nodes (MN) to change their point of attachment to the Internet while still being able to maintain a connection to the network Mobile IP is designed to support the mobility of a user, it is the only current means for offering seamless roaming to mobile computers in the Internet. In this paper, we give a brief survey of Mobile IP operation and functions, as well as proposed Pi-Calculus algorithm of Enhancement Mobile IP (E-Mobile IP) handoff mechanism using Link Layer Information to enhance the performance in term of packet loss and handoff latency.
