Local authentication mechanism for micro mobility in wireless active network environment

By having a local mobility management scheme such as regional registration suggested in IETF, we can perform regional handoffs instead of global handoffs. Regional handoff by micro-mobility techniques shortens the delay in managing mobility in the visited domain since it eliminates the registration process to the home network of mobile nodes, hence it can also decrease the load of HA(home agent). 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. We propose regional authentication mechanism which combines the micro-mobility techniques and active nodes of active access network for wireless environment
