1. Continuous Connectivity in a Wearable Computing Environment Koojana Kuladinithi, Andreas Könsgen, Stefan Aust and Carmelita Görg ComNets, University of Bremen, Germany {koo, ajk, aust,cg}@comnets.uni-bremen.de

2. Outline Continuous Connectivity Mobile Internet Protocol Application scenario Conclusion

3. Continuous Connectivity Improving effectiveness of a field based worker Access to information (weather, traffic, technical data), while on the way to and from the operational sites Contactability of experts (office based, other site based) Continuity of Communications Mobile Internet Protocol

4. Basic Operation  Post-Office forwarding service: Extension to standard IP by introducing: Home Agent Foreign Agent (IPv4 only) Mobile Node Mobile Node Acquire roaming address(care-of address, COA) Register roaming address Home Agent Intercept incoming traffic Tunnel to new location Mobile Internet Protocol

5. Wearable Computing with Mobile IP A field based PABX Servicing & Repairing technician • Check his next job on his voice activated computer whose small LCD display is located close to his eye • Check route & weather conditions • Retrieve data related to PABX • View operation & schematic diagram of the set up at the Organisation • Informs his personal database at office abt his start time of the job. • Finds certain area is not familiar to him • Starts a Video conferencing withan expert at the office • Informs his personal database at office abt his completion time of the job

6. Conclusion Mobile Internet improves effectiveness of the Wearable Computing Environment by enabling continuity of communication
