This paper describes the fundamental concept of analysis and design strategy for an effective deployment of wireless communications for innovative universities or colleges campus that insistently deploys the wireless networks. The extensive use of wireless technologies in university campus has made various respective computer applications such as electronic transactions and electronic learning (e-learning) environments become more energetic. Usually, for the innovative campus network, when deploying wireless communications, most IT Managers/Engineers begin the project by jumping into technical matters, such as deciding upon which approach, technique or standard to use, which vendor to select, and how to overcome the various limitations. These are important elements of implementing wireless communications for innovative campus;however prior to getting too far with the project, the respective IT Managers/Engineers must give vigilant attention to analysis and design strategy in order to wind up with an effective deployment.

Distributed collaboration over the Internet has become increasingly common in recent years, supported by various technologies such as virtual workspace systems. Often such collaboration is ad-hoc, and virtual workspaces are set up anew for each new instance of collaboration. We propose that much of the ad-hoc collaboration can be captured and transformed into patterns for reuse in future collaboration. This paper presents the results of the past five years of our work in this area. We introduce the notion of patterns of virtual collaboration;present a framework for extracting patterns of work in virtual workspace systems;and introduce an information model of virtual collaboration. We then present an overview of our data and process mining methods and reverse engineering techniques for discerning work processes carried out through virtual workspace systems. Finally we present our visual mining techniques that we use to discern aspects of work processes in virtual workspaces.

Testability has many effects on software. In general, increasing testability makes detecting faults easier. However, increasing testability of third party software components is difficult because the source is usually not available. This paper introduces a method to increase component testability. This method helps a user test when the component is reused during integration. First, we analyze a component to gather definition and use information about method and class variables. Then, this information is used to increase component testability to support component testing. Increased testability helps to detect errors, and helps testers observe state variables and generate inputs for testing. This paper uses an example to report the effort (in terms of test cases) and effectiveness (in terms of killed mutants).
Designing component-based application that meets performance requirements remains a challenging problem, and usually requires a prototype to be constructed to benchmark performance. Building a custom benchmark suite i...

Fault tree analyses (FTA) are embedded into UML component models. The UML component models are constructed by employing UML's extension mechanisms in conjunction with component-based software techniques. Taking an application's safety-related requirements into consideration, the elements of FTA are defined as component attributes, and assigned to a UML component model, which is collected in UML profile for safety analyses and architectural design. Based on the thus enhanced architecture specification of the UML component model, it becomes possible to handle hazard analyses and to model safety mechanisms at the same time.

Quality of Services (QoS) management in compositions of services requires careful consideration of QoS characteristics of the services and effective QoS management in their execution. A Web service is a software system that supports interoperable application-to-application interaction over the Internet. Web services are based on a set of XML standards such as Simple Object Access Protocol (SOAP). The interactions of SOAP messages between Web services form the theoretical model of SOAP Message Exchange Patterns (MEP). Web Services Business Process Execution Language (WSBPEL) defines an interoperable integration model that facilitates automated process integration in intra- and inter-corporate environments. A service-level agreement (SLA) is a formal contract between a Web services requestor and provider guaranteeing quantifiable issues at defined levels only through mutual concessions. Based on a prior research work on Message Detail Record (MDR), this paper further proposes a SOAP message tracking model for supporting QoS end-to-end management in the context of WSBPEL and SLA. This paper motivates the study of QoS management in a Web service composition framework with the evolution of a distributed toolkit in an industrial setting.
