  • implementation of a cost effective home lighting control System on Embedded linux with openwrt
    Ubiquitous Computing, 2014
    Co-Authors: Cheongghil Kim, Kuinam J Kim
    Abstract:

    In recent years, the significance of greenhouses has been increased greatly because the world has been facing serious problems with energy as its growing demand. At the same time, home automation Systems have been steadily gaining popularity; growing toward smart home based on Cloud technology. This paper introduces a cost-effective home energy saving System based on a Small Embedded System with remote controlling feature. For this purpose, the System is composed of a wireless router based on Embedded Linux for the platform to develop a low-cost energy control server and a smart phone for remote light control app. The prototype System was implemented by porting OpenWrt onto the wireless router which is connected with an interface board with LEDs attached. The remote access and GUI function were implemented by TCP/IP programming using Apple iPhone. The operation of the remote control System was verified by socket communication between the smart phone and the wireless router, and by USB communication between the wireless router and the interface board. The implementation result shows that an OpenWrt-based wireless router can give benefits of saving energy and safety through lighting control.

  • designing a concurrent hardware garbage collector for Small Embedded Systems
    Lecture Notes in Computer Science, 2005
    Co-Authors: Flavius Gruian, Zoran Salcic
    Abstract:

    Today more and more functionality is packed into all kinds of Embedded Systems, making high-level languages, such as Java, increasingly attractive as implementation languages. However, certain aspects, essential to high-level languages are much harder to address in a low performance, Small Embedded System than on a desktop computer. One of these aspects is memory management with garbage collection. This paper describes the design process behind a concurrent, garbage collector unit (GCU), a coprocessor to the Java Optimised Processor. The GCU, targeting Small Embedded real-time applications, implements a mark-compact algorithm, extended with concurrency support, and tuned for improved performance.

  • applying a model based approach for Embedded System development
    Technical Report Series TUD-SERG-2007-020, 2007
    Co-Authors: Christian Bunse, Hansgerhard Gross, Christian Peper
    Abstract:

    Model-based and component-oriented software development approaches are slowly superseding traditional ways of developing Embedded Systems. For investigating to which extent model-based development is feasible for Embedded System development, we conducted a case study in which a Small Embedded System is developed using the MARMOT approach. In order to evaluate the degree of reuse that might be achieved, the components of the case study are used in the context of different Small projects. Several aspects of reuse, application size, ease of adaptation, and development effort are quantified. This analysis reveals that model-based and component-oriented development performs well for Small Embedded Systems, and it leads to the conclusion that model-driven/component-based development of Embedded Systems enables adaptable applications with higherthan- normal reuse rate. Preprint accepted for publication in 33rd EUROMICRO Conference on Software Engineering and Advanced Applications, 2007, IEEE Computer Society.
