The Mobile IP protocol(MIP) was proposed in response to the fact that mobility is not supported in current version of IP, IP version 4. MIP introduces the concept of mobility agents (home agents and foreign agents) t provide continuous network connectivity to the mobile hosts. As per the original design of MIP, it's also compatible with IPv4. The main disadvantage of Mobile IP is the triangle routing problem which makes routing very inefficient. Also, MIP requires that all the traffic to the mobile node go through the home agent(HA), and thus a failure of the HA would disallow any further communication between the sender and mobile. In this paper, we propose a new routing scheme that reduce both these problems to a great extent without requring the present day IPv4 nodes to bring about changes in their protocols.
