However, achieving situation-based behavior is not straightforward; the situation has to be identified; the functionality that provides the best fit (not always the optimal one) has to be selected from a set of options; and the smart environment has to be configured so that the primary goal can be achieved. This paper introduces an advanced solution for context monitoring and context sharing among software agents; a graphical user interface for defining the scope of context for the application(s) in hand; the matchmaking of ontologies for defining the reasoning rules to be used; and a rule graph as a means of configuring an application's behavior in a way that it is aligned with the goal of the smart environment. The concept has been implemented as part of the maintenance process of a smart building. It is still a challenge to achieve a context that can dynamically update and, above all, expand itself.
Organizational evolution of digital signal processing software development

Digital signal processing (DSP) software is hard real-time software that is a part of the software system needed in a base station. This article reports practical experiences related to organizing the development of embedded software in the telecommunication industry, at Nokia Networks. The article introduces the main factors influencing the development of DSP software and also compares the evolutionary process under study with both selected organizational models for a software product line and a multistage model for the software life cycle.We believe it is vitally important to formulate the organization according to the software architecture, and it is essential to have a dedicated development organization with long-term responsibility for the software. History shows that without long-term responsibility, there is no software reuse. In this paper we introduce a new organizational model for product line development. This new hybrid model clarifies long-term responsibilities in large software organizations with hundreds of staff members and formulates the organization according to the software architecture. Our case needs a couple more constraints to keep it in the evolution stage of the software life cycle. Thus, we extend the evolution phase in the multistage model to make it relevant for embedded, hard real-time software. Copyright�c 2006 JohnWiley & Sons, Ltd.

The ubiquitous system, or the smart environment, lacks an approach that supports scalability and enables semantic interoperability. It is challenging to provide a dynamic behavior at the run time without human intervention. A number of dedicated solutions have been developed for the ubiquitous environment because of its complexity. The dedicated solutions are usually non reusable. An approach is needed that i) is reusable as such or partly, ii) provides the semantic interoperability, iii) enables dynamic and behavioral interoperability between the receiver and sender of the information at run time, and iv) is scalable by being modular, and decoupled. This work proposes a novel approach to managing interoperability and dynamics in smart spaces. The approach includes a Cont...

According to some predictions, there are on the order of 7 trillion such connected electronic devices for 7 billion people by 2020, which would amount to around a thousand devices for every human. The goal of the IoT Strategic Research Agenda (IoT-SRA) is to direct the research efforts in Finland to focus areas of identified significant value creation. The SRA presents the key research challenges for the area that should be addressed in Finland given our research strengths, and outlines possible breakthrough targets. The IoT SRA aims to create the foundation for the success of the Finnish ICT industry and industries that build on ICT and IoT technology. By following the road the SRA defines, Finnish companies will become prime drivers of a global IoT business ecosystem. The SRA presents a roadmap towards the IoT SRA 2017 vision: By 2017 the Finnish ICT industry is a recognized leader in the IoT domain due to its expertise in standards, software, devices, and business models integrating and combining various IoT verticals for diverse industry segments. We live in a world surrounded by tens of billions of devices that interoperate and integrate smoothly with the conventional Internet, provide secure and reliable services, enhance the life of people in healthcare, smart homes, industry automation, and environmental monitoring.

A brisk performance evaluation phase is required after the application modelling to evaluate feasibility of new applications on the platform. GENESYS modelling methodology employing service-oriented component based application design has been extended for this purpose such that application level services are refined

Nevertheless, today's software products are intended to be used in mobile, or alternatively, in embedded devices whose environment changes during the application's execution. These kinds of changes occur especially in applications used in smart spaces. This enforces to think security concerns more dynamically. Thus, software has

With the help of context a smart space application can react to the current situation or be proactive and take into account coming circumstances. This paper describes the ongoing research on how context-awareness - an ability to identify and react - is enabled for the heterogeneous

Our aim is to reach relevant context ontology for smart spaces that are, by their very nature, heterogeneous, pervasive and ubiquitous. We illustrate the usage of the context ontology in a case where lights are switched on according to a calculated wake-up time and the preferences of an individual. With the introduced Context Ontology for Smart Spaces, CO4SS, we managed to perform reasoning actions based on the user’s context.

This paper introduces a process for a designing situation-aware safety service for children with a unique combination of novel participatory tools, a brainstorming workshop, and scenario writing. The design process includes five phases where the service design team, with multi-science expertise, uses the participatory design tools to gather the needs, fears, and hopes from the end users in the very early phases of the design. We report the lessons learned from the usage of the design process by the pupils, their parents and teachers from one primary school in Finland. We used publicity via the news in local and provincial newspapers, radio, and TV to receive feedback and acceptance from the local society. The design process proved to be powerful and it enabled the gathering and receiving of valuable feedback from both end users and the local society.

That calls for i) easy and low-cost interoperability with legacy systems/services and ii) scalability in terms of both overhead and performance results for different classes of applications with different quality requirements.
