Effective Component

The rapid growth in the demand for embedded systems and the increased complexity of embedded software pose an urgent need for advanced embedded software development techniques. Software technology is shifting toward semi-automated code generation and integration of systems from components. Component-based development (CBD) techniques can significantly reduce the time and cost for developing software systems. Furthermore, effective component retrieval is a fundamental issue in CBD. In this paper, we address the issues in designing software repositories for embedded software components. We develop an On-line Repository for Embedded Software (ORES) to facilitate component management and retrieval. ORES uses an ontology-based approach to facilitate repository browsing and effective search. To allow easy browsing of ORES, we analyze the typical ontology relations for software components and develop a Merging and Echoing technique to convert the ontology into a hierarchy suitable for browsing, but without the loss of any critical semantic information contained in the ontology. We also develop an algorithm for grouping search results based on the ontology. Thus, we can display search result groups to avoid having to display a large number of search results or having to prune the results and risk reducing the recall factor. Another important aspect in embedded software is the set of nonfunctional requirements and properties. In ORES, we develop an XML-based specification method to capture nonfunctional properties as well as functional characteristics of components and enable retrieval of relevant components based on these specifications.

Many mobile and wireless devices are connecting to the Internet nowadays, among them, mobile phones and PDAs are the most popular ones. Thus, in this paper, we will focus on how to develop embedded software running on the two devices by using design patterns and Java based software components. Notably, some components may be used directly in an embedded software system, whereas most components must be specialized prior to reuse. Developers have to identify the variation points on these components. In order to develop a reusable embedded software system, we will identify several variation points with some variants, and introduce some useful design patterns for implementing variation points. Consequently, we can customize an embedded software system just through attaching variants on corresponding variation point in our system. The design patterns we are using are property container, strategy, decorator, and model-view-controller. The component technology we are using is J2ME. J2ME is a specification focused on the development of mobile applications. It provides a similar environment as standard Java environment. J2ME's components programming includes the Spotlet programming for PDA, and the MIDlet programming for Java phone. In addition, along with the XML, J2ME can also provide the XMIDlet programming for dynamic downloading and execution of XML-based applications for PDA and Java phones.
