Scheduling is needed in a multitude of smart city domains, such as public transportation, logistics, organization of events and parts delivery in assembly lines. In this paper, we present the architecture and implementation of PickUp Planner, a service that enables scheduling and dynamic routing of connected vehicles for picking up number of users distributed in the city. The service dynamically reconfigures...
Future cellular networks (5G) will be used for a diversity of use cases. Transportation is one domain where cellular networks can play a significant role not only in connecting autonomous vehicles to other vehicles, infrastructures, and people, but also in realizing vehicle teleoperation i.e., vehicle driven by an operator from a distance. In this paper, we assess the feasibility of using a cellular...
In this paper we focus on design of a class of distributed embedded systems that primarily perform real-time controlling tasks. We propose a two-layer component model for design and development of such embedded systems with the aim of using component-based development for decreasing the complexity in design and providing a ground for analyzing them and predict their properties, such as resource consumption...
In this paper, we suggest a service-oriented architecture for planning and execution (SOA-PE) in large scale cyber-physical systems (CPS). SOA-PE provides a clean separation between domain modeling, planning, execution, monitoring and actuation services. This approach helps realize the system-of-systems paradigm allowing the decomposition of system goals into smaller subgoals, thus enhancing the scalability...
5G networks will be a key enabler for the Internet of Things by providing a platform to connect a massive number of devices with heterogeneous sets of network quality requirements. In this environment, 5G network operators will have to solve the complex challenge of managing network services for diverse customer sectors (such as automotive, health or energy) with different requirements throughout...
Adoption of virtualization technology has been limited in industrial automation due to unavailability of mature solutions, and strict timing requirements of control systems. However, current advancement in Virtual Monitoring Machine, multicore technology, virtualization extension and network virtualization has led to increased interest of virtualization in industrial automation. So far, many related...
With multicore controllers becoming available for industrial automation applications, new tools and algorithms to compute efficient partitioning and scheduling solutions for control applications need to be developed. Optimizing the deployment and the schedule of a set of Function Block Diagrams on a parallel architecture are both NP hard. Additionally, control engineers need help to shift from the...
Multicore processors promise to improve the performance of systems, by integrating more and more cores onto a single chip. Existing software systems, such as control software from the automation domain, need adjustments to be adapted on multicores. To exploit the concurrency offered by multicore processors, appropriate algorithms have to be used to divide the control application software into tasks,...
Virtualization is a promising solution to develop complex embedded systems with real-time requirements. This paper discusses the current state-of-the-art in virtualization technologies, with a particular focus on solutions for embedded real-time systems. Several such solutions have been developed over the past decade, and in this paper we give an overview of the more well known technologies and we...
Embedded systems are challenging to design, due to the implementation platform constraints that have to be considered, preferably from early stages of design, next-by system functionality. Hence, embedded system models need to be timing and resource-aware, to make formal verification of extra functional properties applicable at high levels of abstraction. In most cases, a frequent obstacle to the...
