Shorter innovation cycles along with the demand for individualized, high-quality products pose high challenges on today's automated material flow systems. These systems, suitable for producing bulk goods, but inflexible in case of product changes, need to react flexibly to unplanned configurations. Especially in the software domain retroactive adaptations are tedious work and prone to errors. By deploying...
Small unmanned aircraft are being used in an increasing number of applications requiring cooperation between multiple heterogeneous vehicles. Multi-agent control algorithms can be implemented to control such systems but often require an underlying communications framework with integrated payloads. This paper presents a modular heterogeneous multi-agent control framework with payload integration. This...
This paper presents new challenges for the development of reconfigurable wireless sensor networks (RWSNs) that adapt dynamically their behaviors to their environment under different properties. An RWSN is a set of networked nodes that execute reconfigurable software tasks for the control of local sensors. We propose a new design methodology named RWiN of an RWSN using unified modeling language (UML)...
Smart buildings and smart cities rely on interconnected sensor networks that collect data about their environment to support various applications. Developing and deploying the data collection architectures of these systems is a challenging problem. The specificities of the sensor platforms compel software engineers to work at a low level. This makes this activity tedious, producing code that badly...
We present a software configurable and parallelized coprocessor architecture for Linear Quadratic Regulator (LQR) control that can control physical processes representable by a linear state-space model. Our proposed architecture has distinct advantages over purely software or purely hardware approaches. It differs from other hardware controllers in that it is not hardwired to control one or a small...
This paper addresses software design for cyber-physical automation systems that enables invariant properties of the physical system in case of software reallocation to different hardware. The proposed approach is based on the distributed reference architecture of IEC 61499 standard enhanced with a time-stamping mechanism. It is demonstrated that the proposed approach complements the abilities of IEC...
This paper describes a testbed for development, deployment, testing, and analysis of Cyber-Physical Systems (CPS) applications. The testbed incorporates smart network hardware, allowing high-fidelity emulation of CPS network characteristics, and CPS simulation environments to enable high-frequency sensor reading, actuator control and physical environmental changes. We discuss the architecture of this...
This paper outlines an architectural perspective for a multimodal data acquisition to be implemented in order to monitor contamination in urban waterways. The purpose is to develop an approach to detect objects and anomalies in dynamic environmental conditions. For overcoming effects of environmental variations like high reflectivity, heat waves, fog and variable illumination, an implementation with...
This paper addresses the design method of navigation system for the autonomous underwater vehicle (AUV), which includes overall navigation architecture, hardware and software structure. This paper is focused on how to build the integrated underwater navigation module which is applicable to various types of underwater vehicle rather than the navigation algorithm, itself. The autonomous underwater navigation...
The relative significance of available processing/memory resources and cost/power constraints for wireless sensor-actuator nodes depends on the application and use-case scenario. As an example, wireless automation applications usually have diverse processing/memory resource demands and energy constraints, and they bring forth development feasibility as one of the important decision criteria. For similar...
Smart environments represent a relatively uncharted ICT territory where plenty of sensor and actuator devices can be enrolled on-demand in order to realize high value-added services. A few application scenarios, such as Smart Cities, have already been explored. However, in order to finally enable such a paradigm, several issues have to be dealt with. In particular, from a developer perspective the...
This paper describes an agent-based architecture for domotics. This architecture is based on requirements about expandability and hardware independence. The heart of the system is a multi-agent system. This system is distributed over several platforms to open the possibility to tie the agents directly to the actuators, sensors and devices involved. This way a level of abstraction is created and all...
This paper introduces a bio-inspired GAORI robot with renewable energy source and presents its command and data acquisition system for remote commanding as well as data forwarding/backup/relay. The hardware architecture design and software implementation of GAORI command and data acquisition system are presented in this paper.
Heterogeneous wireless sensor networks combine static nodes and mobile nodes. These mobile nodes might present a more sophisticated and powerful computation platform if compared to static nodes. UAVs (Unmanned Aircraft Vehicle) can confer mobility feature to a node, as well as offer a powerful computation platform, including reconfigurable hardware as an execution platform alternative. These types...
The paper proposes the integration of new cognitive capabilities within the well known OpenBTS architecture in order to make the system able to react in a smart way to the changes of the radio channel. In particular, the proposed spectrum sensing strategy allows the OpenBTS system to be aware of other active transmissions by forcing to choose a new radio channel, within the GSM frequency band, when...
The focus of this project is to study the design of a cyber-physical interface for automated vital sign readings in Electronic Medical Record Systems. This is presented as a solution for a need in actual EMR systems where the reading of vital signs is done manually which is error prone and time consuming. The domain application knowledge and prototype used for the development of this paper is made...
This paper describes the technical aspects of the transition to a software product line approach in the automotive domain. One major challenge is the current existence of two different emerging standards for this domain, AUTOSAR and EAST-ADL2. These potential standards should be borne in mind during the software product line introduction because they may someday become mandatory. In addition, the...
One of the banes of modern software development is needing to make design decisions before enough information is available to do so with adequate justification. In this paper, we describe a novel system engineering technique that helps alleviate the problem by allowing many such decisions to be delayed until they can be made with sufficient supporting information. We expect this approach will substantially...
Modern, energy-efficient sensor nodes cover a wide variety of application scenarios. For a fast adapting of these devices to new requirements a concurrent development process of software and hardware extensions must be feasible. Here we present a Hybrid Simulation Environment (HSE) that combines a cycle accurate simulator for MSP microcontrollers written in Java and SystemC, which allows description...
Engine control systems, consisted of ECU hardware, software, sensors, and actuators, are the most significant part of automotive control, and can be considered as mixed-signal systems which interact with engine through sensors and actuators. In this article, we present a component-based modeling and simulation framework for automotive system design. This component framework is compatible with AUTOSAR...
