The following article was published by CEA in the Journal of Internet Services and Applications in November 2017.
A smart environment is equipped with numerous devices that are possibly distributed over different locations (e.g., rooms of a smart building). These devices are automatically controlled to achieve different objectives related, for instance, to comfort, security and energy savings. Controlling smart environment devices is not an easy task. This is due to: the heterogeneity of devices, the inconsistencies that can result from communication errors or devices failure, and the conflicting decisions including those caused by environment dependencies. This paper proposes a design framework for the reliable and environment aware management of smart environment devices. The framework is based on the combination of the rule based middleware LINC and the automata based language Heptagon/BZR (H/BZR). 
A case study with concrete devices, in the field of building automation, is presented to illustrate the framework.

The paper below was published in the German journal "at - Automatisierungstechnik", on June 12, 2017

 

The design of building automation is not seamless but divided into different fragment (HVAC, lighting, sunblinds etc.). Improvement is possible if the first design step includes all fragments to enforce an integrated design workflow. A knowledge based tool supports a nearly automatic design workflow with fast results.

This paper was presented at the 26th International Symposium on Industrial Electronics, held on June 19-21, 2017, in Edinburgh, UK. 
 
The communication between different partners to handle the different tasks during the life cycle of buildings is far from being perfect. Fragmented engineering, lack of data consistency, insufficient system documentation or sensitivity for data sharing are only a few of many problems in this field that have not been efficiently handled through researches as well as in practice. This paper focuses on a deeper analysis of these problems mainly in the planning and engineering phases (they are the basis for all other phases) from both technical and economical point of view. An approach to handle these problems will be presented and thoroughly discussed.

TOPAs - Towards a Comprehensive life cycle approach of Building Automation Systems.pdf

 

This paper was presented at the Coordination Models and Languages, held on June 19-21, 2017, in Neuchatel, Switzerland. 
 
During the last decades a lot of coordination models and languages have been proposed in the literature. These approaches have proven that they can greatly improve the development of distributed applications that are now common. However, to be used by many developers, there is still a gap regarding the available tools.
This paper details a set of tools that have been built to develop applications in LINC, a coordination environment rooted in Linda tuple spaces and Gamma chemical machine approaches. These tools allow developers to design better coordination rules, to monitor and update a running distributed application. The tools proposed here include design and debugging tools. 

 

The 15th Dresden's Researcher Night, held on June 16th, 2017 delighted more than 38000 visitors. Over 680 events were organized by the university, colleges, private institutes and companies of Dresden. 
TOPAs' TUD team has shown the TOPAs demonstrators and discussed with approximately 600 visitors about the future usage of TOPAs' technologies in the Faculty of Computer Science of the Technical University of Dresden. Many people were very interested in learning about energy consumption prediction, failure detection and management, as well as system reconfiguration (in case of failures or additional user's requirements). The TOPAs demonstration has fully addressed the visitors' expectations to learn about innovative solutions to energy problems within buildings.

This paper was presented at the ARM workshop in the ACM/IFIP/USENIX Middleware Conference, held on December 12-16, 2016 in Trento, Italy.  
 
Adaptive systems behaviours can be intuitively programmed, using rule based middleware, as a set of rules. The rules verify conditions and perform actions in order to achieve a set of objectives. However, this raises several problems. First, inconsistencies may result from the fact that an action is not actually performed due to a communication error or a hardware failure. Second, the rules may be conflicting and their sequential chaining may lead to undesirable behaviour. This paper proposes an approach that combines transactional and behavioural reliability (i.e. consistency and no conflict) in adaptive middleware. This approach is implemented using the middleware LINC and the automata based language Heptagon/BZR. A case study, in the field of building automation, is presented to illustrate the approach

Optimization of the energy consumption of sensor networks is traditionally performed either at the sensor node level or at the network level. However, more energy savings can be obtained if the application that makes use of the sensor nodes is considered. In order to achieve such extra energy gains, control theory can be applied. This paper summarizes control strategies implemented to minimize the energy consumption of a set of sensor nodes, while ensuring the application Quality of Service, this latter being mainly expressed with a minimum number of samples that must be available at the application level at each sampling time. With the Control strategies proposed, the sensor network lifetime is increased compared to the case without control strategy at application level. The control strategies have been implemented and evaluated on a real testbed composed of heterogeneous sensor nodes, and using the LINC middleware for node coordination.

Sensorized commercial buildings are a rich target for building a new class of applications that improve operational and energy efficiency of building operations that take into account human activities. Such applications, however, rarely experience widespread adoption due to the lack of a common descriptive schema that would enable porting these applications and systems to different buildings. Our demo presents Brick, a uniform schema for representing metadata in buildings. Our schema defines a concrete ontology for sensors, subsystems and relationships among them, which enables portable applications. Using a web application, we will demonstrate real buildings that have been mapped to the Brick schema, and show application queries that extracts relevant metadata from these buildings. The attendees would be able to create example buildings and write their own queries.

Commercial buildings have long since been a primary target for applications from a number of areas: from cyber-physical systems to building energy use to improved human interactions in built environments. While technological advances have been made in these areas, such solutions rarely experience widespread adoption due to the lack of a common descriptive schema which would reduce the now-prohibitive cost of porting these applications and systems to different buildings. Recent attempts have sought to address this issue through data standards and metadata schemes,but fail to capture the set of relationships and entities required by real applications. Building upon these works,this paper describes Brick,a uniform schema for representing metadata in buildings. Our schema defines a concrete ontology for sensors, sub-systems and relationships among them,which enables portable applications. We demonstrate the completeness and effectiveness of Brick by using it to represent the entire vendor-specific sensor metadata of six diverse buildings across different campuses, comprising 17,700 data points, and running eight complex unmodified applications on these buildings.

The paper presents our work on the Coordination Scheme Editor (CSE). This editor provides a web interface to design building automation rules.  The CSE also offers a monitoring interface to know which scenario is impacted by one or several faulty sensors/actuators. The CSE relies on the LINC middleware to provide coordination across several building automation systems and sensors/actuators technologies.
