METHOD FOR OPTIMIZING ROUTE WHEN A DUAL MOBILE IPv4 NODE IS CONNECTED TO AN IPv6-ONLY NETWORK

摘要

The invention generally deals with wireless communication technology and particularly to a method for achieving route optimization when dual capable MIPv4 mobile node is connected with V6 only network wherein the route optimization allows packets to traverse a shorter route than the default one through the Home Agent using bidirectional tunneling, thus leading to better bandwidth utilization. This invention explains a method for route optimization with dual MIPv4 node in IPv6-only network comprising the steps of: getting configured with visited IPv6 address from a router when Dual capable MN is connected to IPv6 only network; updating HA with V6 address; deregistering BU with CN Via HA; updating CN with V6 address; checking reachability of CN through its V6 address; MN starts sending data packets to CN tunneled in V6 packet once the reachability is verified; and CN sending data packets tunneled directly to MN's V6 address.
