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,...
As more and more Internet of Things (IoT) devices are connected to the cloud services, fog computing has emerged as a new computing model to provide analytic and intelligent services to the end users for fast response time. Among the application layer protocols used for IoT, MQTT and CoAP are two well-known lightweight protocols that run on top of TCP and UDP, respectively. MQTT supports publish/subscribe...

The paper presents the Big data definition and the main characteristics description The model of association between entities and characteristics is constructed. The method of heterogeneous data sharing and bringing to relational data model “entity-characteristic” was created. The testing results of developed methods and algorithms are presented.
The paper is connected with the method for examining the reliability of the RFID-tagged document management system. The system is composed of computers, where the software for supporting processes of the RFID-tagged documents was installed. Besides, the system cooperates with many other elements of the secret office (cabinets, sluices, photocopiers, desks). The examination of the reliability of the...
Hybrid broadcast-broadband TV (HbbTV) is a global initiative that brings new solutions to world of digital television (DTV) in terms of entertainment. In comparison to previous initiatives, different services are additionally provided in HbbTV. This paper describes an application for displaying of hybrid Electronic Program Guide (EPG) for a digital TV receiver. The application works with and without...
This paper proposes a novel signaling compression method to meet the requirement of the MCPTT call service under limited physical carrier capacity of carrier aggregated broadband system. In addition, we design an architecture that hosts compression proxies on both the user and network side without the modification of core network of LTE system. The signaling compression method has been implemented...
Nowadays, web services play a major role in the development of enterprise applications. Many such applications are now developed using a service-oriented architecture (SOA), where microservices is one of its most popular kind. A RESTful web service will provide data via an API over the network using HTTP, possibly interacting with databases and other web services. Testing a RESTful API poses challenges,...
Recently, the video system changes from the limited device based uni-directional to various devices based bi-directional system. Therefore, users can easily access video contents from anywhere, anytime via a various type of devices such as smartphone and tablet. It is expected that various services will be generated by heterogeneous video platforms. With these changes, the video system is required...
This paper focuses on research device management mechanisms such as routers and switches, based on the NETCONF protocol, considered user authentication mechanisms using RADIUS-server and implementation of these mechanisms in currently being developed Eltex Network OS. Reflected the main features of NETCONF protocol — Network Configuration Protocol, produced theoretical and experimental comparison...
AWS Lambda (Amazon Web Services) is the most popular serverless architecture provided by Amazon. It currently supports three platforms: JavaScript, Python, and Java Virtual Machine (JVM). The JVM could be the most complicate platform among the three as there are many languages that target the JVM platform besides Java. In addition, the complex hierarchy of dependencies, versioning, and the class loader...
Printing good-sized complicated practical report forms is one puzzle in application system with B/S architecture. In order to solve this problem, performing data exchange using XML to come true printing is explored. Windows Form in the framework of .NET is embedded in FrontPage. By self-programming, XML document is analyzed and client-side printing is controlled. Fundamental technique on implementing...
The need to apply complex algorithms on large volumes of data is boosting the development of technological solutions able to satisfy big data analytics needs in Cloud and HPC environments. In this context Ophidia represents a big data analytics framework for eScience offering a cross-domain solution for managing scientific, multi-dimensional data. It also exploits an in-memory-based distributed data...
There is a large body of work in the literature about automatic unit tests generation, and many successful results have been reported so far. However, current approaches target library classes, but not full applications. A major obstacle for testing full applications is that they interact with the environment. For example, they access files on the hard drive or establish connections to remote servers...
NewsOne is a dedicated platform that aggregates all the latest news updates from multiple national and international resources and summarizes them to present in a short and crisp words. This online platform provides a service oriented interaction among the users from across web. The main motto of this application is to access the news fast. It will bring news directly without wasting any time for...
The goal of software testing is to find defects before the product is released to the customer. Siemens has a Zero Defect Culture which strives to continuously improve our software testing methods. The current methods use automated testing and manual testing. This paper examines the use of mixed-strength covering arrays, resulting in requiring fewer tests for higher strength coverage. Using the Combinatorial...
The development of wireless technology like Internet Protocol version 6 over Low power Wireless Personal Area Networks, which defines IP communication for resource-constrained networks enables communication on the lower layers, while the diverging and incompatible application layer protocols lead to barriers in the way of information transferring between heterogeneous networks. Fortunately, extensible...
All organizations big or small need to manage their data effectively, both the structured data stored in operational databases and the unstructured data that is spread out across documents. As the data size grows, it becomes essential to move the data to a warehouse so that data is available for adhoc queries and analysis. This data repository of both useful data and documents along with meta data...
The improved computational capabilities and lowcost facilities of smart phones and tablets makes these devices candidates for enterprise application platforms. Business alignment of organizational and inter-organizational systems is a matter for service-oriented solutions. The most common implementation of SOA service is SOAP web service, which support accepted standards of composition, security,...
In heterogeneous database environment, data synchronization is a major issue. For on any government initiative which includes pan India roll out invariably brings along challenges related to fetching of data from various locations like respective zones/states/districts etc, its synchronization, transformation and standardization. Moreover this data usually resides in various different databases like...
