Summary:
Software for Autonomous Underwater Vehicles (AUVs) is usually complex. It involves several complicated tasks such as controller, path planner, map builder, and sensor processor. Distributed processing is unavoidable for such a complex software system with real-time response requirements. Once these processes are distributed over several computers, it is essential that they have some mechanism to communicate to each other to share information. Each process might communicate with several of the other processes. Interprocess communication becomes an important issue. This thesis discusses the design and implementation of a generic distributed toolkit that facilitates the development of distributed software for AUVs. This toolkit makes the details ofinterprocess communication transparent to the programmers involved in the AUV software development. The toolkit provides efficient direct communication between processes and does not impose any constraints on the architecture of the distributed software. Conventional techniques for monitoring/debugging of sequential programs are not applicable for distributed processes. This is because the correctness of a real-time distributed program is determined not only by its "logical" correctness but also its "timing" correctness. Monitoring mainly comprises of observation of the system during its operation. Debugging is mostly a graphical "post-mortem" analyses of the dumps generated by the distributed program. This thesis also presents the design of a window based generic graphical monitoring/ debugging tool.
