The trend towards interconnection of applications has long been recognized as a key challenge for information systems design.  Following these trends, organizations have developed and introduced many distributed systems with different functionalities. Furthermore, computing becomes today increasingly mobile; performance of mobile devices (i.e. PDAs and smartphones) as well as the expansion of high-speed mobile networks allow many tasks to be performed beyond stationary workspaces.

The dramatic growth of stand-alone and heterogeneous parts will negatively affect integration, coordination, and communication aspects within entire solutions. Contemporary solutions focus on stationary systems only; the use of mobile devices is limited to simple scenarios. In order to support the seamless integration of mobile devices, future distributed solutions should take service and service meta information into account: variation of network bandwidth, battery power, availability, connectivity, reachability, sensors data and locations of services and service providers.

In this master thesis we want to analyze how a distributed environment with variety of separated (mobile) service providers implemented with different technologies can be integrated and coordinated. Finding the compromise between performance, comfort, and intelligent intercommunication is main goal of this thesis. Therefore, it is concentrated on the conceptual design of a central middleware component that provides the coordination and communication functionalities for stationary and mobile entities. In order to prove some possible communication scenarios the middleware has to be implemented in a demonstrator.
