A Real-Time Wireless Distributed Embedded System (RTWDES) is formed by a large quantity of small devices with certain computing power, wireless communication and sensing/actuators capabilities. These types of networks have become popular as they have been developed for applications which can carry out a vast quantity of tasks, including home and building monitoring, object tracking, precision agriculture,...
Partitioned software architectures were conceived to fulfill security and avionics requirements where predictability is extremely important. Both, the availability of new processors and an increased necessity of security, have opened new possibilities to use efficiently this approach. Avionic industry has consolidated the Integrated Modular Avionics (IMA) as a solution to manage the software growth...
Hierarchical scheduling has recently been used to provide temporal isolation to embedded virtualised systems. Response time analysis is a common way to derive a schedulability test for these systems. This paper points out that response time analysis for hierarchical fixed-priority scheduling found in the literature is only exact for tasks of the highest priority domain. For the rest of the tasks is...
The integration of embedded real-time control systems with the physical world via sensors and actuators (pervasive computing systems) is creating a nascent infrastructure for a technical, economic and social revolution. In most advanced real-time control applications, the tasks have different criticality, flexible timing constraints and variable execution time. For instance, autonomous mobile robots...
Many computer-controlled systems are distributed, consisting of computer nodes and a communication network connecting the various systems. It is not uncommon for the sensor, actuator, and control calculations to reside on different nodes. Wireless connections permit to apply these control systems in a wide spectrum of application and environments. In this paper, we describe the development process...
The design of embedded control systems should be addressed in both the controller definition and its implementation. While the design of the controller is based on control theory, the implementation is designed by assuming the principle that control loops can be modeled and implemented as periodic activities. Periodic activities that can be organise attending to different implementation criteria....
