In Service Oriented Architecture, Quality of Service (Qos) represents an important issue which is often considered when selecting and composing services. For receiving up-to-date information, non-functional properties can be continuously monitored using current methods. Because of the occurrence of monitoring at every time of service calling, the current methods imposes some overhead on the SOA. The...
This paper discusses different aspects of performing monitoring in the context of software intensive systems. The focus is especially on cases where the observed system is distributed, and the monitoring system needs to be secure, dependable and capable to adapt to a number of dynamic scenarios during the system evolution. Based on analysis of monitoring needs in this type of a domain, a set of core...
Due to the fact that software systems cannot be tested exhaustively, software systems must cope with residual defects at run-time. Local recovery is an approach for recovering from errors, in which only the defective parts of the system are recovered while the other parts are kept operational. To be efficient, local recovery must be aware of which component is at fault. In this paper, we combine a...
Along with the infiltration of wireless sensor network in every field of our life, sharing sensor network resources in Internet environment is one of key problems which must be solved by wireless sensor network application. This paper expounds Web Service technology and uses Web Service technical framework for reference to design a new kind of service-oriented sensor network structure. And finally,...
Cloud computing, as an emerging computing model, is drawing much attention from academia and industry. Storage resource, computing resource and network resource are three basic resources in a cloud computing infrastructure. How to utilize these resources efficiently and conveniently is a big challenge for building a good cloud computing infrastructure. This paper presents a service-oriented storage...
Enterprise business strategy and IT strategy is disjointed, which leads to the failure of many IT projects. The main reason of failure is lack of IT Enterprise architecture development at the initial stage of enterprise informatization. This paper discusses the content of IT planning, enterprise architecture and their relationship, and expounds the process of enterprise architecture development using...
There are many factors, such as temperature, humidity, concentration of oxygen and carbon dioxide, influencing freshness of garden stuff. An intelligent monitoring system was designed to ensure the quality of it. In order to balance the environmental deviation between different areas, the system used multi-channel sensors to cycled check environment. Without effecting control accuracy, the system...
Under service oriented architecture (SOA), a system- such as an enterprise-consists of multiple heterogeneous servers (service providers), which may be distributed over a wide area of network, and may be managed under different administrative domains. One of the goals of this work is to enable the system as a whole (i.e., the enterprise) to impose global constraints on the interactive behavior of...
Mobile healthcare (m-healthcare) systems are regarded as a solution to address skyrocketing healthcare costs without reducing the quality of patient care. It is our aim to build an m-Healthcare platform based on the service-oriented computing paradigm. We are developing a service-oriented architecture (SOA) for m-healthcare services platform, called SOAMOH that shall also support interfacing with...
In a number of scenarios, services generated using a model-driven development (MDD) approach could benefit from ??reflective?? access to the information in the models from which they have been generated. Examples are monitoring, auditing, reporting, and business intelligence scenarios. Some of the information contained in the models of a service can statically be generated into its source code. In...
Web-oriented Architectures provide a way of designing an IT system by using a variety of Web Procedures, i.e., procedures (or services) called over the Web. The idea of (typically atomic) components that are black boxes, have interfaces, and can be assembled into a larger process is fundamental and has existed since the early days of distributed systems. Two particular types of modern distributed...
Within service orientation (SO) web services (WS) are the defacto standard for implementing service-oriented systems. While consumers of WS want to get uninterrupted and reliable service from the service providers WS providers can not always provide services in the expected level due to faults and failures in the system. As a result the fault management of these systems is becoming crucial. This work...
This paper proposes a Diseases Notification System which is designed using a SOA pattern. Disease notification is an import component of the disease control systems. A successful diseases notification system will deliver positive effects for human beings. The proposed system is designed and implemented by use of the Business Process Execution Language for the business process layer and Enterprise...
The principal role of embedded software is the transformation of data and the interaction with the physical world stimulus. The main concern in developing embedded software for network application is the lack of published best practice software architecture for optimizing performance by means of reducing protocol processing overhead, memory usage, and power consumption. This paper presents the implementation,...
