With the advent of portable mobile devices and increasing usage of wireless communication medium, achieving seamless application space as the end-points change network attachment points is a demanding task. Connection Oriented mobility requires moving the connection abstraction to new attachment point without disturbing existing applications. As mobile nodes change the network attachment points, the existing connections become stale. Single layer solutions either require an infrastructure or significant re-engineering of protocol stack, which are hard to deploy.
This thesis uses simple, light-weight re-organization (meta-engineering) on the protocols of the core networks to enhance them by making them interactive and transparent. Hidden information from the network core is exposed to higher layers for adaptability. A secure, flexible, application-aware cross-layer interactive architecture called Interactive Protocol for Mobile Networks(IPMN) was developed to handle non-indelible periods of disconnection and network handoffs. The inherently hidden information in one layer can be used by other layers to achieved optimized results. Events form Link Layer Network Layer and Transport Layer related to mobility are identified and subscribed by the application.
The proposed solution achieves rapid, loss-free vertical handoffs, is event-based and does not require any infrastructural deployment. Since the triggers to the events are in application space there is no significant re-engineering of the core network or any protocol stack. Solutions are deployed in the application space, making it easy to modify, augment or replace existing solutions.
