With the extensive application of industrial sensor networks in the embedded field, the interconnection communication between the embedded node is proposed for the cross-LAN/WAN communication needs. Traditional communication schemes using proprietary protocols and sink nodes do not fully meet the interoperability needs. Web Services technology has the characteristics of openness, platform interoperability,...
The paper describes the principles of building IT infrastructure of information systems. It specifies the advantages of using service-oriented architecture (SOA) for information and software systems construction. The platform designed to implement an information system IT infrastructure on the basis of SOA and the full-duplex exchange protocol WebSocket is described. Methods of developing communication...
Using Commercial off-the-shelf (COTS) software over networks that are Disconnected, Intermittent and Limited (DIL) may not offer acceptable performance. Frequent network interruptions for both shorter and longer periods, as well as long delays, low data and high packet error rates characterize DIL networks. In this paper, we designed and implemented a prototype proxy to improve the performance of...
Message serialization is a format of messaging leveraging Web services to exchange data over the network. Serialized messages are processed at the server and sent as objects over the network to the client to be consumed. While, serialization process minimizes network bandwidth requirement but then incurs overhead at the communicating ends. This research contributes to the study of message exchange...
The deployment of web services in dynamic environments like cloud infrastructures offers flexible solutions to provide required resources to maintain web services availability and performance during peak demands. However, the lack of control and monitoring tools on the cloud infrastructure exposes the deployed web services to security threats. While there are security solutions that focus on web services,...
The aim of this system is to use open source APIs to invoke and process the results of the Web services and to apply confidentiality and integration to the result of the Web services. In this system Web Services are requested using URL (Uniform Resource Locator) query to the WWW instead of SOAP message. When invoking the web services using JAX-RPC (Java Api for Xml-Based Remote Procedure Call) with...
In the paper by W. Dai et al. [2015], a formal mapping between IEC 61499 and service-oriented architecture (SOA) is presented, and an SOA-based execution environment architecture is described. In this comment, we discuss the mapping and the execution environment architecture, as well as the suggested potentials for exploiting those. We present specific arguments and make cases that call the authors'...
Smartphones and other connected devices rely on data services, such as web services (WS) and Google Cloud Messaging (GCM), to share the information they collect or use. Traditionally, these services were classified according to their efficiency or their delivery time, but, when dealing with battery operated devices, another important parameter is the power consumption. In this paper, we present the...
NEON conducts annual LiDAR flights over several ecologically unique sites within the continental United States. One of the products derived from the LiDAR acquisitions is a canopy height model (CHM), required to make inferences about vegetation structure and annual changes in growth. It is hypothesized that the flight acquisition parameters are sufficient to allow NEON's CHMs to detect inter-annual...
Current Web-based Services are highly heterogeneous not only on data but also with regard to service interaction. Despite their heterogeneity, composition of these services is required in order to achieve additional functionality. Semantic descriptions and composition algorithms for heterogeneous services have been recently proposed. However, existing techniques do not take the Publish/Subscribe paradigm...
Web services which allow the interoperability and communication of heterogeneous systems in the Web through Internet protocols, are also subject to attacks a well as destructive as sophisticated. Contrariwise, very few solutions exist to ensure the availability of Web services in the presence of these attacks. In order to tackle these issues, we propose a comprehensive and complete attack-tolerance...
The web services technology has been created to support communication between heterogeneous platforms. Despite its maturity, built upon more than a decade of experience, research and practice show that the technology still fails to connect web service client applications to servers, even when the programming languages involved are the same. This is especially troubling for service providers, as a...
Nowadays, cloud computing is hard to effectively sustain the implementation of the commercial model of Internet Service globalization. There is a growing trend to build an environment of cloud service, with the capacity to serve anytime and anywhere, by mutual cooperation between cloud service providers around the world. However, this tendency will raise a key issue which is how to provide a benign...
This work contains the implementation of techniques and recommendations OWASP on a SOA prototype developed with J2EE. To its design and coding we used some WS-Security specifications, Metro framework, MVC as architectural pattern, Facade and DAO as design patterns. The prototype was validated in terms of design, coding and security through some tools such as: Structural Analysis for Java, SonarQube,...
Cloud Computing has emerged as a new paradigm of computing that builds on the foundations of Distributed Computing, Grid Computing, and Virtualization. Cloud computing is Internet-accessible business model with flexible resource allocation on demand, and computing on a pay-per-use as utilities. Cloud computing has grown to provide a promising business concept for computing infrastructure, where concerns...
The volume of data exchanged by computer networks is gradually increasing over time, which provides the need for performance and interoperability between different platforms and systems. In this line, there are several studies dedicated to service-oriented software architectures and resource consumption models. However, a few of them are focused on the development of generic tools for the dynamic...
Global Positioning Systems (GPS) now provide great benefits for companies that need the location of a device or a point of interest. Today, smart mobile devices have increased exponentially by the features that these devices are able to offer thanks to their processing power. This document develops an application that provides a location service for university users, giving the facility to know the...
This article describes the infrastructure and architecture required for the implementation of an automation system for the current SIMERT Tariff Municipal System of Rotating Parking in the city of Loja. The best technological architecture was identified among the models of technological architectures based on web services as SOA, SOAP and REST. The required network infrastructure was specified in...
Within the context of the ISO/IEEE 11073 family of standards for point-of-care (PoC) medical device communication, a communication protocol specification for a distributed system of PoC medical devices and medical IT systems that need to exchange data, or safely control networked PoC medical devices by profiling Web Service specifications, is defined by this standard. Additional Web Service specifications...
Different with the sparseness of moving nodes in delay tolerant network (DTN), the mobile terminals with its short distance wireless interface can also be seen as mobile nodes, which were endowed as agents because of the social properties of their users. A self-organized agent picking (SOAP) network is established that the data with limited-copies can transfer across the SOAP network between random...
