Based on Zig Bee, DSP, and Web Services, this paper proposes a distributed power monitoring and control platform (PMCP) with easy-deployment and flexible-extension considerations. Specifically, a type of wireless power monitoring module (WPMM) is designed for easily deploying the point monitoring points. In the WPMM, a DSP module is designed to rapidly compute power parameters and implement power...
With the proliferation of Internet-enabled devices and the growing adoption of the Service Oriented Architecture (SOA), users increasingly require services that can meet their functional and nonfunctional requirements. In this paper, we propose a novel framework for Web service provisioning, which relies on brokered Service Level agreements (SLAs), between clients and service providers, and a publish/subscribe...
Collecting and analyzing real-time data of a distributed wireless sensor network system is very challenging since it combines a series of processes to continuously monitor and respond to a wide variety of events. This paper presents an event-driven, real-time data collection system architecture for an independent living spaces monitoring system. A service-replacement-based timestamp matching structure...
Building business solutions may require combining multiple existing enterprise services. In SOA paradigm this can be accomplished using composite services; a key feature in this paradigm. Composite services can be in turn recursively composed with other services into higher level solutions allowing to build new business services from existing ones. However, determining the optimal composition in terms...
Complex Event Processing over Web service event streams poses huge challenges with regard to efficient, scalable execution as well as expressive models and languages that account for the dynamics in long-running queries. We present a distributed query platform that tackles these problems. Our novel query model permits to specify inputs that provide data for other inputs and need to be processed first...
As the Web Services technology is widely used in the enterprise's core business, how to manage these resources is becoming to extremely important problem. In this paper, after analysising the characteristics of resouce management in distributed environment and the main content of WSDM, a novel Web Service management scheme is introduced, and then the main components in the scheme is introduced, as...
Fractal image compression algorithm has some problems, such as high computational complexity and long time consumption. In this paper the parallel implementation of fractal image compression algorithm in Web service environment is discussed. The experiments show this algorithm can greatly reduce the compression time and achieve a high speedup at the same quality of decompressed image. The proposed...
Distributed environments hosting specific and dedicated computing resources are serving nowadays more and more scientific and commercial applications. Finding the right resource in distributed environments in term of performance is not an obvious task. This paper is addressing the issue of selecting the right service deployed in a distributed environment for any applications or workflow engines that...
Service Level Agreements (SLAs) need to be monitored at runtime to assure that the Business Level Agreements (BLAs) / Business Level Objectives (BLOs) are indeed satisfied in the realized business workflow and allow the organization to adjust its business processes best to the environment. In this paper, we show how multiple SLAs specified on various observable attributes can be formally specified,...
This work discusses PatrasSense, a system utilizing a range of technologies for monitoring environmental conditions, based on the concept of participatory monitoring. We discuss here the main issues in this category of applications, and its relation to the Real World Internet vision. We are interested in the use of sensors for collecting data related to the quality of life in urban areas, making it...
High performance platforms composed of commodity computing resources, such as grids and peer-to-peer systems, have greatly evolved and assumed an important role in the last decade. Nevertheless, their wide commercial use still depends on the establishment of an effective quality of service (QoS) infrastructure in those environments. For this reason, a variety of proposals have recently emerged in...
The idea of M2M platform proposes a completely new system architecture for positioning and monitoring applications with wider coverage and higher communication efficiency. With the comparison of the original communication mode to the M2M-based one, the communication interface is changed in the new communication solution for the application side accessing to the platform, which is finally designed...
DIES system for designing and improving enterprise business scenarios is proposed. Such scenarios are executed and monitored in an SOA environment. Many metrics are gathered, and strong/weak aspects are pointed out. DIES allows the improvement of a scenario's performance, quality, and usability. Due to technology-agnostic API the system supports any extensible business scenario technology, and it...
Monitoring is important for managing a Cloud computing environment. This task should be performed without modifying the implementation of the offered Cloud services. In this paper, a monitoring approach that neither modifies the server implementation nor the client implementation is presented. The proposed approach, called AOP4CSM, is based on aspect-oriented programming and monitors quality-of-service...
Real time monitoring system of digitized agricultural water supply is a complex engineering. In this paper, the software and hardware design principal of real time monitoring and management system in water resources and the integrated characteristics of structure are introduced. The general planning of real time monitoring system in integrated system in agriculture water supply is proposed. This system,...
With powerful features and cross platform character, web service has been applied in the field of information technology widely. To meet dynamic needs of enterprises, it tends to generate new web applications through service compositions. Due to flaw of designed process or incorrect input, to composite service may encounter various faults during execution. Moreover, the faults often continue to accumulate...
In software product lines, engineers derive products using feature-based configurators. Such tools do not scale well to complex (non linear, multi-user) configuration processes. We address this issue by extending a feature-based configurator with multi-view support and by integrating it with a workflow management tool.
Considering numerous of credible problems takes place in the distributed, loosely coupled, flexible and dynamic Web service environment because many factors, such as service provider, service user and service quality and so on, is uncertain, which all these problems exited lead the normal running of system to face serious threats. Therefore, this article, through processing the user feedback information...
Since the 21st century, modern service industry has mushroomed around the world, and the application systems in modern service industry are usually built based on the reuse of other third party services in a distributed and loose-coupled way. Consequently, there will be a greater need for the provisioning and lifecycle management of services. In this paper, we analyze the drawbacks of current service...
Recently, Top-k queries in distributed applications have attracted much interest in many different areas such as network and monitoring systems, information retrieval, sensor networks. Some efficient algorithms, such as TA, BPA, are regarded as centralized process in distributed applications. However, to some ad hoc ranged Top-K queries have less flexibility towards updating and low efficiency in...
