This paper describes the design and development of a proof-of-concept platooning application, which operates in a mobile and dynamic environment and makes use of architectural and middleware solutions that were proposed in the scope of the HIDENETS project. With this application it is possible to demonstrate the practical feasibility of a hybrid system(More)
—Hard real-time operating systems have been mostly designed for uniprocessors. Driven by the high computational demand of real-time systems, these operating systems have been redesigned for multiprocessors. Researchers have been identifying issues that affect the predictability of multiprocessor hard real-time systems. These sources of unpredictability make(More)
Building distributed embedded systems in wireless and mobile environments is more challenging than if fixed network infrastructures can be used. One of the main issues is the increased uncertainty and lack of reliability caused by interferences and fading in the communication, dynamic topologies, and so on. When predictability is an important requirement,(More)
This paper addresses a resilient cooperative engine for robot teams within the context of the surveillance of physical areas. Due to the unreliability in the wireless communication between robots, a middleware must offer some resilience to the control application and guarantee that the robots never collide. We present an architecture for the robots to share(More)
