An Interoperability Cross-Block Chain Framework for Secure Transactions in IoT

The purpose of this research is to deal with effective block chain framework for secure transactions.The rate of effective data transactions and the interoperability of the ledger are the two major obstacles involved in Blockchain and to tackle this issue,Cross-Chain based Transaction(CCT)is introduced.Traditional industries have been restructured by the introduction of Internet of Things(IoT)to become smart industries through the feature of data-driven decision-making.Still,there are a few limitations,like decentralization,security vulnerabilities,poor interoperability,as well as privacy concerns in IoTs.To overcome this limitation,Blockchain has been employed to assure a safer transaction process,especially in asset exchanges.In recent decades,scalable local ledgers implement Blockchains,simultaneously sustaining peer validations of transactions which can be at local or global levels.From the single Hyperledger-based blockchains system,the CCT takes the transaction amid various chains.In addition,the most significant factor for this registration processing strategy is the Signature to ensure security.The application of the Quantum cryptographic algorithm amplifies the proposed Hyperledger-based blockchains,to strengthen the safety of the process.The key has been determined by restricting the number of transactions that reach the global Blockchain using the quantum-based hash function and accomplished by scalable local ledgers,and peer validations of transactions at local and global levels without any issues.The rate of transaction processing for entire peers has enhanced with the ancillary aid of the proposed solution,as it includes the procedure of load distribution.Without any boosted enhancement,the recommended solution utilizes the current transaction strategy,and also,it’s aimed at scalability,resource conservation,and interoperability.The experimental results of the system have been evaluated using the metrics like block weight,ledger memory,the usage of the central processing unit,and the communication overhead.

Problem of interoperability in semantic web service system

In order to fully realize semantic interoperability among distributed and heterogeneous applications on the web, a set of effective interoperability mechanisms is presented. This mechanism adopts service interactive interfaces （SII） and service aggregative interfaces （SAI） modeled with abstract state machine （ASM） to abstractly describe the behavior of the invoked web service instances, which makes business processing accurately specify tasks and effectively solves the problems of communication and collaboration between service providers and service requesters. The mechanism also uses appropriate mediators to solve the problems of information and coinmunication incompatibility during the course of service interaction, which is convenient for service interoperability, sharing and integration. The mechanism＇ s working principle and interoperability implementation are illustrated by a use case in detail.

BIM Methodology Applied in Structural Design: Analysis of Interoperability in ArchiCAD/ETABS Process

The Building Information Modeling (BIM) methodology considers the representation of the building as a virtual BIM model and its main concept is to centralize all the information generated throughout the development of the project. Structural design involves a set of tasks, namely, structure definition, structural analyses, and after the generation of drawings and technical documentation. In all processes, it is required confidence in data transferred between the BIM systems used, and to support this, a high level of interoperability is claimed. The present study aims to evaluate the degree of interoperability between the BIM-based platforms, ArchiCAD (Graphisoft), Revit (Autodesk), and ETABS (CSI). Two-way data flows between these systems were explored using distinct transfer strategies: add-in applications;Industry Foundation Classes (IFC) standard data format. The research made allows identifying the most appropriate procedure to be adopted by structural engineers, given the interoperability limitations verified, enabling the establishment of a practical guide of sequential procedures on the development of structural designs using BIM tools.

The Interoperability of Distributed DBMSs in a CORBA-Based Multidatabase System

One way of achieving interoperability among heterogeneous, distributed DBMSs is through a multidatabase system. Recently, there is an increasing use of CORBA implementation in developing multidatabase systems. Panorama is a multidatabase system that has been implemented on the top of CORBA compliant namely VisiBroker. It aims to achieve interoperability among Oracle, Sybase and other different DBMSs through the registration of these DBMSs to Panorama and through the single global query language PanoSQL designed for this system. In this paper, we first introduce CORBA for the interoperability in multidatabase systems. Then, a general view for our designed multidatabase system, Panorama, has been given. In section four, we introduce the global query language PanoSQL designed to achieve interoperability among the different DBMSs implemented in Panorama. Then, as an example, we present the registration of Oracle to Panorama in order to achieve interoperability in this system. And finally, a conclusion and the future work for this system have been given.

Minimal-Length Interoperability Test Sequences Generation via Genetic Algorithm

A novel interoperability test sequences optimization scheme is proposed in which the genetic algorithm （GA） is used to obtain the minimal-length interoperability test sequences. During our work, the basic interoperability test sequences are generated based on the minimal-complete-coverage criterion, which removes the redundancy from conformance test sequences. Then interoperability sequences minimization problem can be considered as an instance of the set covering problem, and the GA is applied to remove redundancy in interoperability transitions. The results show that compared to conventional algorithm, the proposed algorithm is more practical to avoid the state space explosion problem, for it can reduce the length of the test sequences and maintain the same transition coverage.

Use of LTE for the Interoperability between Different Generations of Wireless Communication

This paper looks potential approaches to interoperability as well as inter-technology mobility using Long Term Evolution (LTE) between different generations of wireless communication. Focus is given on how these approaches can be used in interoperable service deployment, access technology integration, service continuity and smooth migration to LTE by maximizing the use of legacy networks coverage. One of the most important interoperability criterions is the handover latency. Using NCTUNS6 simulator it is shown that LTE (4G) provides less handover latency in comparison to that of other generations of wireless communication system for homogeneous environment.

A framework for interoperability of BPEL-based workflows

With the prevalence of service-oriented architecture （SOA）, web services have become the dominating technology to construct workflow systems. As a workflow is the composition of a series of interrelated web services which realize its activities, the interoperability of workflows can be treated as the composition of web services. To address it, a framework for interoperability of business process execution language （BPEL）-based workflows is presented, which can perform three phases, that is, transformation, eonformance test and execution. The core components of the framework are proposed, especially how these components promote interoperability. In particular, dynamic binding and re-composition of work-flows in terms of web service testing are presented. Besides, an example of business-to-business （B2B） collaboration is provided to illustrate how to perform composition and conformance test.

Using a Health Level 7 Interoperability Bus to Support Legacy Systems in the Health Domain

In order to reduce the effort in the integration and actualization of heterogeneous healthcare legacy systems that should share a common database, we propose the creation of an interoperability bus using the HL7 standard—the HL7Middleware. This interoperability bus is an intermediate layer responsible for the communication between a database, health information systems and medical equipment, called HL7Server. Connected systems use the HL7 messaging semantics to store and retrieve data from the database. We validate our approach with respect to two different criteria: performance and integration costs. Benchmark tests were executed with and without the use of HL7Middleware and with different network bandwidths. These results demonstrated that the performance of the interoperability bus is higher when compared to traditional database access for larger volumes of data and when the bandwidth of the user is considerably lower than the bandwidth of the connection between HL7Server and database. The overall development and deployment cost was considered low and the reusability degree of wrapper code was considered high, thus suggesting a progressive reduction of the integration costs of additional services and subsystems of an organization.
