Knowledge Based Framework: A Case Study on Fast, Reliable, and Secure Web Services in UAVs

Advanced and complex embedded systems as multicore and multiprocessor systems are becoming common and this has stimulated the development of critical applications for them. UAVs (Unmanned Aerial Vehicles) constitute a typical application of a complex critical embedded system. One concept that can result in radically different solutions in UAVs is the use of Service-Oriented Architecture (SOA). The increasing use of SOA in critical applications demands dependable and cost effective techniques to ensure high security. In this paper we develop a different kind of services for avionics with different parameters (security, reliability and performance) to provide the use of SOA in a less critical part in the whole systems. The use of these services and the KBF (Knowledge Based Framework for Dynamically Changing Applications) presented in this paper can give more intelligence to the UAVs and provide a new form of segregating the UAV mission from the vehicle itself. The services were developed and a performance evaluation was conducted showing the benefits in choosing one service or another.
