Blockchain‐Based Reliable Fog‐Cloud Service Solution for IIoT

Industrial Internet of things (IIoT) deploys a large number of smart devices to obtain industrial data, which will be transmitted to cloud for analysis to improve industrial productivity. The management of large-scale devices is complicated, and it's also a challenge to choose a high-quality cloud for data analysis as the number of with similar functions increases. To address these issues, we propose a reliable fog-cloud solution with blockchain-based fog-cloud architecture. In fog layer, we build a management blockchain between fog servers and design a management method for industrial devices; In cloud layer, we construct a blockchain between cloud providers to form an open service market. Quality of and reputation based matching algorithm and reputation-based consensus algorithm are designed. The simulation results show correctness and efficiency of algorithms, and validate effectiveness of our proposed solution.

Development of techniques to optimize the technical parameters of transport cargo complexes

Transition to a competitive environment and open service market in the transport sector has high requirements for all aspects of its functioning. To ensure an adequate level of competitiveness, rail transport should provide the customers with the most efficient and low-cost services in both transportation, and cargo handling, which is impossible without efficient technical equipment of cargo complexes.As a result of the research, the dependences of the value of the admissible efficiency criterion - specific profit of TPC enterprises per unit of value of cargo complex fixed assets, on the amount of production resources - shunting locomotives, cargo handling machines and sizes of storage facilities were obtained.The results have shown the presence of a complex polynomial dependence of the operating costs of the shunting locomotives and mechanisms in the sphere of cargo operations on the number of service units. Optimum size of storage facilities stepwise depends on the car traffic volume intensity.Using the obtained dependences allows to optimize the technical equipment of existing cargo complexes and set their optimal process parameters at the design and equipping stage.

Insurance-Based Business Web Services Composition

As more web services that implement core functions of business are delivered to customers with service charges, an open and competitive business web services market must be established. However, the qualities of these business web services are unknown without real experiences and users are unable to make decisions on service selection. To address this problem, the authors adopt insurance into business web services composition. In this paper, the authors propose three insurance models for business web services. Based on the insurance models, the authors propose an approach to compute the expected profit of composite business web services, which can be used as a criterion for business web services composition. The insurance of business web services and the criterion for business web services composition will help service competition and boost the development of more business web services and the software industry.

Evolution of SOA Concepts in Telecommunications

The telecommunications industry has always been service-oriented. However, the convergence-driven need to deliver seamless services across different access networks has forced operators to embrace new approaches, including the intelligent network, Web-services-based APIs, and, most recently, the IP multimedia subsystem. Today, SOA is considered state of the art for service-delivery platforms. Such platforms for value-added services have evolved from the intelligent network (IN) and object-oriented programming interfaces to recent Web-services-based platforms. They've exploited the most recent information technologies to implement an open set of service components. Web 2.0's recent emergence, meanwhile, has further pressured telecom companies to implement an open service market based on an open set of enabling services and service components.

A Review of Approaches to Developing Service Management Systems

As service management systems are deployed in an open service market environment, the pressures on their developers to shorten development times and improve the flexibility of systems will increase. Component reuse may help in alleviating some of these pressures; however, while object-oriented reuse is used in the definition of interfaces for management systems, the systematic application of reuse to the systems' internal design is not well established. This paper examines some of the approaches applicable to service management system development from the Telecommunications, Distributed Systems, Internet and Software Engineering fields. Experience in applying some of these approaches is presented, and based on this, refined approaches to service management system development are discussed.

Using mobile agents to support interorganizational workflow management

This article argues that the mobile agent approach is well suited for sporadic communication in open distributed systems, especially for rather ''loose'' cooperations across local and organizational boundaries. In an increasing number of cases, management of distributed business procedures reaches beyond such boundaries. This means, for most existing workflow management systems, that cooperating partners are required to give up their local autonomy. However, for cases in which business partners intend to cooperate but still need to preserve their local autonomy, process participation on the basis of mobile agents represents an appropriate mechanism. This article shows how such process integration can be achieved. It also demonstrates how the Common Open Service Market (COSM) system software can be extended in order to use petri-net based process definitions that realize mobile agents in an integrated distributed system platform.

Developing distributed multimedia telecommunication applications

The emerging open services market transforms services into tradable goods. It involves users; customers; service, content, and middleware providers; and network operators. This market requires effective methods to: provide new services to meet niche market demands; support customized services; provide appropriate accounting and billing mechanisms; support personal and terminal mobility, and meet information interchange security requirements such as authorization, confidentiality, and integrity. Efficient processes will reduce investment risks and let us benefit from software and hardware product development advances. To meet these needs requires an appropriate infrastructure that supports the object oriented development of distributed multimedia telecommunication applications.

A formal description of open distributed processing (ODP) trading based on guidelines for the definition of managed objects (GDMO)

New requirements of growing computer networks and information systems have an influence on extended client/server models with increased functionality. This forms the basis for service management in distributed systems which is realized by a service trading concept. This paper studies the requirements derived from the Open Distributed Processing (ODP) Reference Model in order to consider an open service market. Furthermore, it examines management possibilities for describing the service trading scenario. Because of similar architectures and properties ODP services, service offers, types, exporters and traders are mapped onto management components and modeled as managed objects. Therefore, the Guidelines for the Definition of Managed Objects (GDMO) are used. The final concept allows a precise and unambiguous study of the service trading scenario and provides means for exporting and importing of service offers in a distributed environment.
