TRE-DSP: A traceable and revocable CP-ABE based data sharing scheme for IoV with partially hidden policy

With the popularity of the Internet of Vehicles (IoV), a large amount of data is being generated every day. How to securely share data between the IoV operator and various value-added service providers becomes one of the critical issues. Due to its flexible and efficient fine-grained access control feature, Ciphertext-Policy Attribute-Based Encryption (CP-ABE) is suitable for data sharing in IoV. However, there are many flaws in most existing CP-ABE schemes, such as attribute privacy leakage and key misuse. This paper proposes a traceable and revocable CP-ABE-based data sharing with partially hidden policy for IoV (TRE-DSP). A partially hidden access structure is adopted to hide sensitive user attribute values, and attribute categories are sent along with the ciphertext to effectively avoid privacy exposure. In addition, key tracking and malicious user revocation are introduced with broadcast encryption to prevent key misuse. Since the main computation task is outsourced to the cloud, the burden of the user side is relatively low. Analysis of security and performance demonstrates that TRE-DSP is more secure and practical for data sharing in IoV.

TEDARİK ZİNCİRİNDE KURU DÖKME VE GENEL YÜK TERMİNALLERİ: ALİAĞA İÇİN BİR DELPHI ÇALIŞMASI

Maritime transportation plays a vital role in the flow of various cargoes within a supply chain system. In this context, seaports have also started undertaking the provision of value-added services in the supply chain management, where logistics costs and service effectiveness are vital. Terminals that handle dry bulk cargoes which have low unit prices and high elasticity to transportation prices, and general cargoes that require different planning and management for almost each operation have significant roles in the chain as well. This study aims to determine and evaluate the role of dry bulk and general cargo terminals in the supply chain with the value-added logistic services by focusing on Aliağa Region. Delphi technique has been employed to shed light on the role of the dry bulk and general cargo terminals and manufacturers in the scope of supply-chain and logistics-based components. Findings indicate that service effectiveness is important as well as operational efficiency in such terminals and service characteristics should be improved to become more supply-chain oriented. Value-added services are considered as a differentiation factor where customers pay great attention.

Value-added services in institutional repositories in Spanish public universities

Introduction. The aim of the present study was to analyse the value-added services offered by institutional repositories in Spanish public universities. Method. Information was collected on the main characteristics of repositories in Spanish public universities and the value-added services they offered, using a checklist with twenty-five items divided into three dimensions: information on the repository; information on the records; and instructions for use and dissemination. Analysis. We determined the frequency of each value-added service in the repositories included in the study and analysed the main modalities in which these services were offered. We also analysed the similarity between repositories using multidimensional scaling methods. Results. We found high variability between repositories and indicated that some value-added services were widely offered whereas others were only provided by a few repositories. Conclusions. We believe that the provision of value-added services could have a direct impact on repository use because such services are related to many of the reasons that explain repository under-utilisation, such as low perceived usefulness, difficulties depositing work and lack of knowledge about what should or can be deposited.

Three-Dimensional Maturity Model of Regional Power Users Against the Background of the Ubiquitous Power Internet of Things

As the Ubiquitous Power Internet of Things (UPIoT) is being developed, the data volume collected by various terminals such as smart electricity meters is increasing daily. The efficient extraction of information from massive data and the provision of value-added services to users, power grids, and market entities are crucial aspects and research directions. A data analysis and application framework for smart meter data based on cloud-fog computing and data contextualization is established, and a data contextualization model based on three-dimensional (3d) maturity analysis of industrial power users is proposed to evaluate the power consumption characteristics of users from the three aspects of the load level, power consumption behavior, and interaction. The results of a case study show that this model allows power grid operators to understand quickly and intuitively the load behavior pattern and power demand of industrial power users, thereby enabling an efficient and accurate assessment of the power supply and an ability to provide value-added services.

A Multi-Site NFV Testbed for Experimentation With SUAV-Based 5G Vertical Services

With the advent of 5G technologies, vertical markets have been placed at the forefront, as fundamental drivers and adopters of technical developments and new business models. Small Unmanned Aerial Vehicles (SUAVs) are gaining traction in multiple vertical sectors, as key assets to generate, process, and distribute relevant information for the provision of value-added services. However, the enormous potential of SUAVs to support a flexible, rapid, and cost-effective deployment of vertical applications is still to be exploited. In this paper, we leverage our prior work on Network Functions Virtualization (NFV) and SUAVs to design and build a multi-site experimentation testbed based on open-source technologies. The goal of this testbed is to explore synergies among NFV, SUAVs, and vertical services, following a practical approach primarily governed by experimentation. To verify our testbed design, we realized a reference use case where a number of SUAVs, cloud infrastructures, and communication protocols are used to provide a multi-site vertical service. Our experimentation results suggest the potential of NFV and SUAVs to flexibly support vertical services. The lessons learned have served to identify missing elements in our NFV platform, as well as challenging aspects for potential improvement. These include the development of specific mechanisms to limit processing load and delays of service deployment operations.

Make-or-buy configurational approaches in product-service ecosystems and performance

This research examines firm boundary configurations for manufacturers' product-service offerings. We argue that the building of a product-service ecosystem through collaboration with service providers in certain types of business services can increase performance as a result of the superior knowledge-based resources coming from specialized partners. By using fuzzy set qualitative analysis on a sample of 370 multinational manufacturing enterprises (MMNEs), the results reveal that effective servitization is heterogeneous across manufacturing industries and across business service offerings. The findings indicate that most industries achieve their highest performance through collaborations with value-added service providers in two out of three of the service continuum stages (Base and Intermediate services); while keeping the development of Advanced services in-house. The results help to contextualize the best practices for implementing service business models in MMNEs by detailing which service capabilities should be retained in-house and which should be outsourced to specialized partners in various industrial contexts.

Privacy Management in Social Internet of Vehicles: Review, Challenges and Blockchain Based Solutions

The Internet of Things (IoT) paradigm has integrated the sensor network silos to the Internet and enabled the provision of value-added services across these networks. These smart devices are now becoming socially conscious by following the social Internet of Things (SIoT) model that empowers them to create and maintain social relationships among them. The Social Internet of Vehicle (SIoV) is one application of SIoT in the vehicular domain that has evolved the existing intelligent transport system (ITS) and vehicular ad-hoc networks (VANETs) to the next phase of Intelligent by adding socializing aspect and constant connectivity. SIoV generates a massive amount of real-time data enriched with context and social relationship information about vehicles, drivers, passengers, and the surrounding environment. Therefore, the role of privacy management becomes essential in SIoV, as data is collected and stored at different layers of its architecture. The challenge of privacy is aggravated because the dynamic nature of SIoV poses a major threat in its adoption. Motivated by the need to address these aspects, this paper identifies the challenges involved in managing privacy in SIoV. Furthermore, the paper analyzes the privacy issues and factors that are essential to be considered for preserving privacy in SIoV environments from different perspectives including the privacy of a person, behavior and action, communication, data and image, thoughts and feelings, location and space, and association. In addition, the paper discusses the blockchain-based solutions to preserve privacy for SIoV.

Enabling Multi-Mission Interoperable UAS Using Data-Centric Communications.

We claim the strong potential of data-centric communications in Unmanned Aircraft Systems (UAS), as a suitable paradigm to enhance collaborative operations via efficient information sharing, as well as to build systems supporting flexible mission objectives. In particular, this paper analyzes the primary contributions to data dissemination in UAS that can be given by the Data Distribution Service (DDS) open standard, as a solid and industry-mature data-centric technology. Our study is not restricted to traditional UAS where a set of Unmanned Aerial Vehicles (UAVs) transmit data to the ground station that controls them. Instead, we contemplate flexible UAS deployments with multiple UAV units of different sizes and capacities, which are interconnected to form an aerial communication network, enabling the provision of value-added services over a delimited geographical area. In addition, the paper outlines an approach to address the issues inherent to the utilization of network-level multicast, a baseline technology in DDS, in the considered UAS deployments. We complete our analysis with a practical experience aiming at validating the feasibility and the advantages of using DDS in a multi-UAV deployment scenario. For this purpose, we use a UAS testbed built up by heterogeneous hardware equipment, including a number of interconnected micro aerial vehicles, carrying single board computers as payload, as well as real equipment from a tactical UAS from the Spanish Ministry of Defense.

Study on the application of digital fiat currency in peer-to-peer investment and lending

Currently, peer-to-peer lending platforms are faced with the risk of funds misappropriation and lack effective means to ensure funds security and transaction consistency. The traditional method focuses on the assessment and control of the platform to indirectly guarantee the security of transactions and execution of contracts. This paper proposes a new solution based on digital fiat currency (DFC), which creates a trusted operating environment via a DFC wallet application service system and uses joint signatures to monitor the flow of funds to ensure security. Moreover, the proposed solution implements smart contracts in DFC wallets to achieve transaction consistency in order to ensure that the transaction process is open, transparent, safe, and controllable. In this way, troubled Internet finance platforms can transform themselves into DFC value-added service providers, playing a more transparent and regulated role in promoting inclusive finance in the digital currency ecosystem.

Social Internet of Vehicles: Architecture and enabling technologies

The key goal of Internet of Things (IoT) has been the provision of value-added services based on the ubiquitously available smart devices that can offer diverse services by interacting with each other. However, the paradigm has evolved to its next phase, Social Internet of Things (SIoT), with the inception of an idea to empower these devices with consciousness. This cognizance enables these smart devices to socialize with each other based on shared context and mutual interests. The Social Internet of Vehicles (SIoV) applies SIoT concepts in the vehicular domain to revolutionize the existing ITS (Intelligent Transport System) by adding value to existing VANET (Vehicular Ad-hoc Network) technology. This paper presents a scalable SIoV architecture based on Restful web technology. Furthermore, this paper emphasizes the importance of web technology to meet the required interoperability to support the composition of numerous services. The paper also discusses the enabling technologies and protocols.

Characteristics of Logistics Outsourcing in Bulgaria: The Perspectives of the Logistics Service Providers and their Customers

AbstractThe increased demand and supply of logistics services bring together the logistics service providers (LSPs) and the companies that outsource logistics activities. LSPs stand in between those companies and their customers, thus playing an essential role for supply chain integration. If the two parties have different viewpoints of the processes in the supply chain, the fulfillment of the goal to satisfy the end customers may be hindered. The purpose of this article is two-fold: First, to investigate the characteristics of logistics outsourcing in Bulgaria from the perspectives of the logistics service providers and their customers, and more specifically, to compare their viewpoints concerning the motives for outsourcing, the methods and contents of communication and some relationship management aspects; Second, to assess the relations of the communication and relationship management aspects to customer satisfaction. This article is based on empirical data provided by 138 manufacturing and trading companies and 136 LSPs and collected through two structured questionnaires designed to address the researched issues. The data were analyzed using descriptive statistics and the independent samples t-test. The research found that the service related reasons for logistics outsourcing are prevailing and that LSPs overestimate, compared to manufacturing and trading companies, motives related to service, organizational capabilities and relationships, while more manufacturing and trading companies concern as important the availability of logistics assets and the provision of value-added services. The research also found that both the LSPs and their customers consider that the extent of sharing of knowledge and information essential for material flow integration is very low and that the usage of team meetings and joint teams is quite rare. Also, customers do not view their relationships with the LSPs as so collaborative as viewed by the LSPs. Furthermore, the research proved the existence of positive relationships between customer satisfaction and communication through team meetings and joint teams, knowledge sharing concerning material flow management and relationship management issues such as trust, mutual problem solving, understanding the logistics strategy of the other party and respecting its financial interests. The research findings may help fill in some of the gaps between LSPs and their customers. They point the need for LSPs to include in their service offerings more value-added services and to invest in assets that provide reliable and flexible services for their customers. The research also highlights the importance of knowledge sharing and trust building and reveals great potential for effective trust-based alliances between LSPs and their customers that could help them extract more competitive benefits from their relationships.

Value-added service providers for mobile education: empirical challenges and analytics

More people have access to Multimedia Messaging Service (MMS, a.k.a. mobile picture messaging) than to the Internet, but mobile education markets have yet to adopt MMS as a content delivery mechanism. This paper investigates the role of carrier interoperability as an enabler of MMS in mobile multimedia distance learning. Using instructor reuse of content and learner access to content as feasibility criteria, we empirically evaluate the performance, user adoption, and commercial market of MMS-based mobile education. This study deployed a value-added service that broadcasts videos via MMS to cell phones, and conducted a 9-month public education campaign with weekly broadcasts on breast cancer. We selected a video format and markup language that is compatible with domestic carriers and cell phones, and supports existing educational material. To contrast behaviors between participants with and without access to the Internet, we offered participants the same content via MMS, email and the Web. 277 participants enrolled in the campaign; 120 opted to receive the videos via mobile messaging, and 157 had Internet access and opted to receive videos via email or the Web. Campaign analytics reveal that all participants without Internet access successfully received the MMS video broadcasts, and significantly, one-third of participants with Internet access opted to receive the videos via MMS as well. We conclude with a discussion of why participants with Internet access may have chosen MMS over Internet-based alternatives. We also estimate the size of the market for MMS-based mobile education, and distinguish it from the person-to-person messaging market. This research is beneficial to educators targeting diverse demographics and education disparities, and to mobile commerce economists evaluating emerging markets.

Business ecosystem strategies of mobile network operators in the 3G era: The case of China Mobile

In order to define the mobile network operators' strategies of building value network in the 3G era, this paper applies the ecosystem principles to the mobile industry through a China Mobile case study. Based on an analytical framework of such principles, this paper reviews China Mobile's ecosystem, and identifies its success factors and problems. The results indicate that a complete ecosystem, where mobile network operators collaborate closely with value-added service providers, content/application providers, equipment and device manufacturers, and other involved organizations, can promote the development of mobile data services substantially. Therefore, mobile network operators should play a central role in the ecosystem by managing the entire value-chain and setting up proper value-sharing mechanisms. However, while doing so, problems may arise because of regulatory issues and information asymmetry. High-value common assets, a centralized management system, partner selection schemes and continuous innovations are important success factors.

Network transformation: drivers, opportunities and challenges

The traditional role of the network operator as connectivity provider is no longer viable. To survive in this hyper-competitive environment, carriers are looking to re-invent themselves as value-added service providers. If they want to prevail in this new market environment telcos must take decisive steps to transform their network, systems, people and processes, leveraging a single, converged, IP-based infrastructure.

On designing peer-to-peer systems over wireless networks

With the advance in wireless communication technology and the increasing number of mobile users, peer-to-peer computing, in both academic research and industrial development, has recently begun to extend its scope to address problems related to mobile devices and wireless networks. This paper is a performance study of peer-to-peer systems over wireless networks. We show that the crosslayer approach performs better than separating the overlay from the access networks with a comparison of different settings for the peer-to-peer overlay and underlaying wireless ad hoc network. We then present a performance model towards in-depth understanding of those systems. Our results provide useful guidelines for mobile operators, value-added service providers and application developers to design and dimension peer-to-peer systems over wireless networks.

Service quality and customer satisfaction measurement of mobile value-added services: a conceptual review

As the competition between mobile value-added service providers becomes very tight, each company has to be able to provide high-quality services and thus better satisfy their customers. Unfortunately, despite the increasing need for an objective measurement of service quality, there is no general agreement among service marketing scholars on how it should be conceptualised and measured. This paper presents several models of service quality measurements that can be used to assess mobile value-added service quality. This paper also discusses the measurement of customer satisfaction and how it relates to service quality.
