Secure Fast Handoff Mechanism in Wireless Active Network Environment

To reduce signaling load in the mobile IP, mobile nodes do not register their locations with the HA every time they move in same local domain. Instead, they register only when they cross a domain that consists of a number of routers. To register the location a mobile node sends regional registration request to the GFA through AR and receives back the reply from the GFA. After registration, the GFA and other FAs maintain entry for the mobile node in their visitor lists. Using the characteristics of the active network, by employing active nodes in the wireless regional mobility management environment, we can optimize the mechanism of registration and path setup for the mobile data traffic. But, authentication problems exist in local domain. We propose regional authentication mechanism which combines the micro-mobility techniques and active nodes of active access network for wireless environment
