- This paper evaluates the performance of the IEC 61850-90-5 protocol stack transmitted over a latency optimized non-commercial 3GPP LTE network through experiments in a lab environment. IEC 61850-90-5 is designed for Phasor Measurement Unit (PMU) communication but can also be extended to other areas of control and protection in smart grids, using the routable GOOSE and routable sample value features. The test was carried out using a PC that emulated a PMU in sending periodic IEC61850-90-5 packets. Different IEC 61850-90-5 packet sizes and transmission rates were considered to determine the availability, throughput and latency of the LTE based network. The latency was minimized by applying a low latency scheduling mechanism and local breakout where user plane functionality of the core network is located at the edge of the Radio Access network. From the results it can be seen that an LTE network with latency optimized configuration performs well in terms of throughput and latency whereas a reference network without local breakout show significantly higher latency and jitter.

Konferensbidrag (refereegranskat)abstract
- Settling down the software architecture for embedded system is a complex and time consuming task. Specific concerns that are generally issued from implementation details must be captured in the software architecture and assessed to ensure system correctness. The matter is further complicated by the inherent complexity and heterogeneity of the targeted systems, platforms and concerns. In addition, tools capable of conjointly catering for the complete design-verificationdeployment cycle, extra-functional properties and reuse are currently lacking. To address this, we have developed Pride, an integrated development environment for component-based development of embedded systems. Pride is based on an architecture relying on components with well-defined semantics that serve as the central development entity, and as means to support and aggregate various analysis and verification techniques throughout the development - from early specification to synthesis and deployment. Pride also provides generic support for integrating extra-functional properties into architectural definitions.

Feasibility of migrating analysis and synthesis mechanisms from ProCom to IEC 61499
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This report presents the initial results from the Assist project at Mälardalen University, funded by the ABB Software Research Grant Program. The project aims to bridge the gap between recent academic research achievements in the area of control- and model based development of embedded systems, and concrete industrial needs and state of practice in this domain. Concretely, the focus of the project is to investigate how novel timing analysis and code synthesis techniques developed in the context of ProCom, an academic component model for embedded systems, can be extended and adapted in order to be applicable to IEC 61499.

Classification and Survey of Component Models
- 2010
-
Konferensbidrag (refereegranskat)abstract
- As component-based software engineering is growing and its usage expanding, more and more component models are developed. In this paper we present a survey of software component models in which models are described and classified respecting the classification framework for component models proposed by Crnković et. al. This framework specifies several groups of important principles and characteristics of component models: lifecycle, constructs, specification and management of extra-functional properties, and application domain. This paper gives examples three component models using the classification framework.

Konferensbidrag (refereegranskat)abstract
- This paper describes PRIDE, an integrated development environment for efficient component-based software development of embedded systems. PRIDE uses reusable software components as the central development units, and as a means to support and aggregate various analysis and verification techniques throughout the whole lifecycle - from early specification to deployment and synthesis. This paper focuses on support provided by PRIDE for the modeling and analysis aspects of the development of embedded systems based on reusable software components.

Konferensbidrag (refereegranskat)abstract
- One of the challenges in development of embedded systems is to cope with hardware and software components simultaneously. Often is their integration cumbersome due to their incompatibilities, different specifications and different approaches in their development. In this paper we present a component-based technology for building distributed embedded systems consisting of both embedded hardware devices and software components. To obtain a uniform view on hardware and software we have developed a new component model – UComp. Our technology consists of UComp component model that allows treating remote devices as components, and a run-time framework that supports this component model when the system is deployed. To evaluate the principles we have developed a prototype tool that implements the technology and uses Universal Plug and Play (UPnP) standard for communication between system parts, and demonstrated a feasibility of the approach.

Konferensbidrag (refereegranskat)abstract
- In component-based and model-driven development it is common to model embedded applications in a platform-independent manner. As an example, some approaches allow development of distributed applications while abstracting away from details of communication between platform nodes. Using such an approach requires to implement this communication before an executable system is deployed. Currently it is common to automatically implement this communication on the level of code, while providing it on the model level is mostly a task that needs to be done manually. In this paper we present a framework for automatic generation of inter-node communication by adding communication components to software models. The framework provides flexibility in the level of automation of generation decisions, and is defined in a way which allows adding support for new communication media or protocols. We have implemented the generation framework for the IEC 61499 standard and provide a prototype generation tool, which we use for examining the applicability of the approach.

Adding Support for Hardware Devices to Component Models for Embedded Systems
- 2011
-
Konferensbidrag (refereegranskat)abstract
- Component-based development promises many improvements in developing software for embedded systems, e.g., greater reuse of once written software, less error-prone development process, greater analyzability of systems and shorter time needed for overall development. One of the aspects commonly left out of component models is communication of software components with hardware devices such as sensors and actuators. As one of the main characteristics of embedded systems is the interaction with their environment through hardware devices, the effects of this interaction should be fully included in component models for embedded systems. In this paper we present a framework that enables inclusion of hardware devices in different phases of the component-based development process, including system design, deployment, analysis and code synthesis. Our framework provides a way for software components to explicitly state their dependencies on hardware devices, promotes reuse of software components with such dependencies and provides a basis for including hardware devices in analysis of component based embedded systems. We evaluate the feasibility of our approach by applying it to the ProCom component model.
