3 This presentation focuses on Web services and interoperability between fixed and mobile networks Image for Topic 1 Mobile users collect information. Image for Topic 2 The deployed HQ gathers information. Image for Topic 3 Result: A common operational picture. 3

4 ile users use heterogeneous communications ment Image(s) supporting above assertion obile users take an active part in a mission, reporting nts back to the HQ.

5 Q gathers information and shares it with other yed networks. has fixed infrastructure, and ys to the mobile users. Interoperability across networks is ensured using back to back IP radios. Image or equations supporting the headline assertion Web services provide application level interoperability.

7 ks to network and application interoperability, we can e a common operational picture. Mobile users report incidents back to the HQ. ge supporting above assertion The HQ is able to gather and visualize this information.

8 ce Registries Communication between client, registry and service: 1. Look up/search 2. Response 3. Contacting the service

9 rvice Registries The liveness problem The availability problem

10 ntralized solutions are usually more chatty than alized solutions: Need to optimize data rate irements! Piggybacking Data compression Caching & timeouts
