In the region of the Vale because of its natural relief, flood is recorded along the basin of the Itajai River since 1850. Floods are natural phenomena that are often devastating bringing great damage to man and nature. Flee the human capacity, to prevent such phenomena occur. However, it is possible to develop preventive measures to minimize these impacts. Basically there are two types of preventive...
This article presents the results of the design, implementation and validation of a system for remote measurement of Radio Spectrum for stations fixed monitoring composed for the equipments measurement vector network analyzer ZVL6 spectrum analyzer mode and the NBM550 broadband field meter. The solution is an Information and communications technology - ICT service because it involves not only measuring...
Now-a-days the web services are uprising technology which appeals lots of attention from both academic and industry. The quality of service has been one of the major challenges in the web services. If the web services become operational then the service providers with Service Level Agreement (SLA) need to consider and monitor with respect to the quality of web services and SLA. The most important...
The Nuri configuration tool uses automated planning techniques to reconfigure computing infrastructures from one declarative state to another, while maintaining any required constraints at all stages of the generated workflow. This paper presents the results of our experiments using Nuri to relocate complete 3-tier web applications between two BonFIRE sites. We describe the architecture of the tool...
As part of web services life-cycle, providers frequently face decision about changes without a clear understanding of the impact on their clients. The identification of clients' consumption patterns constitute invaluable information to support more effective decisions. In this paper, we present a framework that supports the discovery of service usage profiles, to bring awareness on the distinct groups...
Developers often rely on penetration testing tools to detect vulnerabilities in web services, although frequently without really knowing their effectiveness. In fact, the lack of information on the internal state of the tested services and the complexity and variability of the responses analyzed, limits the effectiveness of such technique, highlighting the importance of evaluating and improving existing...
An Service Level Agreement (SLA) is a contract between service provider and consumer, and includes appropriate actions to be taken upon violation of the contractual obligations. To ensure the negotiation on an SLA is reasonable by reference the measured history data. The paper proposes a feasible Web Service Level Agreement (WS-SLA) Establishing Framework, which can flexible define trustable SLA requirements...
Wireless sensor networks (WSNs) belong to emerging technologies where network devices can interact with the surrounding environment by sensing physical parameters. Recently, with the dissemination of mobile devices to Internet connectivity, users can interact with sensor networks and collect environmental data, anytime, anywhere using user-friendly mobile applications. Following the Internet of Things...
Service evolution management imposes complex challenges to a service provider. Identifying which changes are necessary and choosing the ones to implement are some of the decisions that providers have to face. The decision making process involves the estimation of change effects to minimize the impact over the direct and indirect clients of the service portfolio. While most existent works address either...
SaaS (Software as a Service) is a modern approach to deliver large scalable enterprise software as a service on Internet. Cloud computing platform provides the scalability, availability and utility computing for services on Internet. There are many technical challenges involved in SaaS development. One of them is multi-tenancy, which allows single instance of software to serve multiple organizations...
With the evolution of mobile networks, web services play a tremendous role in many aspects of our life. Therefore, the service providers have to guarantee an acceptable QoS level especially for those offering challenging services such as multimedia applications. Web services provisioning is used to allocate particular services to the tasks of business processes. One of the challenges in web service...
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...
This paper presents an online monitoring system for operator situation awareness using real-time synchrophasor measurements developed under a DOE R&D and demonstration project. The system provides wide area power system visualization, near real-time event replay and early warning of potential stability problems. The technologies implemented in this system include the memory residence object oriented...
The paper presents a solution with the server components from a teleassistance / tele-monitoring system to assist elderly persons and/or post-discharged patients. The system consists of units located at the homes of the monitored persons collecting and sending medical and environmental data from sensors and a call centre with a server for recording and monitoring the data. Specialized staff will support...
Due to the growth of potential of Wireless Sensor Networks (WSN), now becomes possible to use this technology in various new generation services such as monitor environment characteristics like temperature, humidity, among others. WSNs are emerging as a new paradigm, gathering information in a collaborative way, where independent sensor nodes collect and share information. In the last few years ubiquitous...
Aimed at emission of a huge amount of sulfur dioxide during making thermal process and resulted in major air pollution sources, the paper designed a sort of flue gas online monitoring system for thermal power plant. Based on B/S architecture, the professional platform of SCADA, GIS and AERMOD is respectively built, and the system layers are separated and integrated by means of .NET platform. And data...
Aiming to discover the most suitable service cater to the discovery request of service consumer which includes functional requirements and nonfunctional requirements, this paper proposes a service registry model named as SRC (Service Registry on Cloud) which is an extension of the keywords based service registry model and deployed as a cloud application to provide behavior-aware and QoS-aware service...
From the perspective of legacy systems of Ningxia public business information services platforms involved, proposed SOA Legacy System integration framework based on web service. At the same time, Legacy System is divided into different categories according to their characteristics. We provide web service wrap approaches for different categories of Legacy System. It is an important role in our next...
As a new computing paradigm, Cloud computing has been advocated by IT industry and academia. It can provide lots of services, however, how to manage these services and guarantee the quality of service, has become one of the key factors for the development of Cloud computing. This paper proposes a hierarchical architecture model of Cloud services resources management and monitoring by integrating the...
