Collecting information about faults, state of surrounding environment and equipment is crucial in systems that could jeopardize human lives, such as trains. Normally, data are obtained via analog sensors which do not have any interface to allow their integration with software systems. Additionally, acquisition and transport of sensor data could suffer interferences in the train's environment due to...
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 Internet of Things (IoT) considers interconnected things e.g., devices that consumes web services through the internet. Such kind of devices may vary from smart phones, smart TVs, medical devices or industrial devices. Thanks to the development of the ICT field, many standards supports the existence of the IoT devices: HTTP (Hypertext Transferring Protocol), MQTT (Message Queue Telemetry Transport),...
The Internet of things (IoT) is a rapidly evolving technology capable of transforming numerous areas of our lives. Smart Grid (SG) is one of such areas, which has an immense potential of development, following the advances in IoT technology. The goal of the current survey is to summarize the infrastructure and applications of IoT in SGs. The infrastructure aspect is described from the viewpoints of...
We discuss how global types, aka multiparty session types, provide a complementary perspective on workflow models within the jABC modeling framework. On a reference example from the Semantic Web Services Challenge we show how the service orchestrations of jABC workflow applications can be expressed as service choreographies based on global types. Roles, identified with sets of logically related Service-Independent...
Neither provider nor user are willing to use Web services (WSs) technologies in sensitive domains without some measure of security. The users, on one hand, want to guard their personal information against unauthorized parties. While, the providers, on the other hand, wish to hide their trade secrets and internal know-how. In our previous works, we suggested the use of the Symbolic Observation Graph...
In this work we apply test derivation methods for (extended) finite state machines for testing the functionality of the Communication Protocol between the cash register software and the Loymax service when conducting cash transactions. The Protocol was provided by Loymax that is the company involved in the development and support of loyalty programs. We analyze the difficulties that occur when we...
Hiking a relevant web service in the current environment full of various options is similar to looking for a needle in a haystack. The best possible web service is the one that completely fulfills the required functions while satisfying the QoS requested by a user. In this paper, we introduce a new context-based solution based on QoS (Quality of Service) exploiting both functional and non-functional...
One of the main concerns of Cloud storage solutions is to offer the availability to the end user. Thus, addressing the mobility needs and device's variety has emerged as a major challenge. At first, data should be synchronized automatically and continuously when the user moves from one equipment to another. Secondly, the Cloud service should offer to the owner the possibility to share data with specific...
In this paper, an architectural framework for Web Service Security System that secures Web services effectively from message alteration attacks, Man-in-the Middle (MIM) attacks and Denial of Service (DoS) attacks has been proposed and implemented. This proposed system provides intelligent mechanisms for effective detection and preventions of message alteration attacks at message level, man-in-the...
This paper studies enhancement of Multi-Path TCP(MPTCP), which is one of new transport-layer protocols of TCP/IP protocol suites, by IP routing for improvement of Quality of Experience for a Web service (WebQoE). In order to confirm the effect of IP routing on WebQoE, the author performed experiments with subjects. In the experiment, the subjects assess Quality of Experience of two actual Web services...
This paper presents a case study of an application prototype for shipbuilding industry using RESTful web service. Majority of database applications for traditional enterprises are based on the two-tier with simple client-server or the three-tier with additional RPC middleware. Because the outdated old configuration is not extensible, an alternative is required to link the database to the Web or mobile...
We are in Big Data technology, through which we analysis of the large volume of data like, peta data. Where there are many challenges in bigdata processing like, scalability issues, heterogeneity, error-handling, privacy, timeliness, source, and visualization, at all stages of the data analysis pipeline from data acquisition to final out come of data. To over come above significant problem, the technical...
Internet of Things (IoT) is a technological revolution which provides the vision of connected world of Things. But varieties of technological challenges are there which restrict its full adoption in our day to day life. Among them Privacy and security are the area of major concern in IoT. This paper focuses on the communication with RESTful web services via mobile client in the context of IoT. For...
The Internet of Things (IoT) technology, based on the wireless sensor network, is developing rapidly and permeating into agriculture including livestock farming. Our research focuses on the problem that current industrial IoT system for livestock farming is tightly coupled, hard to expand, and with poor network performance. In this paper we proposed an integrated framework of smart livestock farming...
Native Web communication protocols are the pivotal components of Web services, applications and systems. In particular, HTTP is a de facto protocol standard used in almost all Web services and systems. Consequently, it is one of the crucial protocols responsible for the performance of Web services and systems. HTTP/1.1 has been successfully deployed in Web services and systems for the last two decades...
Expressing and matching the security policy of each participant accurately is the precondition to construct a secure service composition. Most schemes presently use syntactic approaches to represent and match the security policy for service composition process, which is prone to result in false negative because of lacking semantics. In this paper, a novel approach based on semantics is proposed to...
This paper presents a distributed architecture for asynchronously implementing a class of nonlinear signal processing systems as web services, which in turn can be used to solve a broad class of optimization problems. As opposed to requiring specialized servers, the presented architecture requires only the use of commodity database backends as a central resource, as might typically be used to serve...
As the Internet of Things continues to grow rapidly in the coming years, the number of devices with limited resources will continue to grow as well. These so-called constrained devices typically implement specialized protocols and data formats for increased efficiency. While this reduces the load on constrained devices, it also limits the usability of such devices for their users. This paper presents...
Pervasive computing offers environments in which user needs or tasks are fulfilled without demanding their attention. Context-aware service composition is a central aspect to achieving this, in which services are discovered and composed in response to context to meet user needs. Since pervasive computing environments are inherently dynamic and heterogeneous, context-aware service composition is a...
