TL;DR: An Integer Linear Program and a randomized rounding algorithm are proposed and the obtained results show that the social cost of all players can be reduced significantly via allowing cooperation among network service providers in service caching.
Abstract: With the development of 5G technology, mobile edge computing is emerging as an enabling technique to promote Quality of Service (QoS) of network services. In particular, the response latency of network services can be significantly reduced by deploying cloudlets at 5G base stations in mobile edge clouds. Network service providers that usually deploy their services in remote clouds now shift their services from the remote clouds to the network edge in the proximity of users. However, the permanent placement of their services into edge clouds may not be economic, since computing and bandwidth resources in edge clouds are limited and relatively expensive. A smart way is to cache the services that are frequently requested by mobile users in edge clouds. In this paper, we study the problem of service caching in mobile edge network under a mobile service market with multiple network service providers completing for both computation and bandwidth resources of the edge cloud. We propose an Integer Linear Program (ILP) and a randomized rounding algorithm, for the problem without resource sharing among the network service providers. We also devise a distributed and stable game-theoretical mechanism for the problem with resource sharing among the network service providers, with the objective to minimize the social cost of all network service providers, by introducing a novel cost sharing model and a coalition formation game. We analyze the performance of the mechanism by showing a good guaranteed gap between the solution obtained and the optimal one, i.e., Strong Price of Anarchy (SPoA). We finally evaluate the performance of our algorithms by extensive simulations, and the obtained results show that the social cost of all players can be reduced significantly via allowing cooperation among network service providers in service caching.

TL;DR: IoT Passport is motivated by the familiar use of passports for international travel but with greater dynamism, and enables platforms to establish arbitrary trust relations with each other containing specific rules for intended collaborations, enforced by a combination of smart contracts.
Abstract: Internet-of-Things (IoT) is a rapidly-growing transformative expansion of the Internet with increasing influence on our daily life. Since the number of "things" is expected to soon surpass human population, control and automation of IoT devices has received considerable attention from academia and industry. Cross-platform collaboration is highly desirable for better user experience due to fragmentation of user needs and vendor products with time. Centralized approaches have been used to build federated trust among platforms and devices, but limit diversity and scalability. We propose a decentralized trust framework, called IoT Passport, for cross-platform collaborations using blockchain technology. IoT Passport is motivated by the familiar use of passports for international travel but with greater dynamism. It enables platforms to establish arbitrary trust relations with each other containing specific rules for intended collaborations, enforced by a combination of smart contracts. Each interaction among devices is signed by the participants and recorded on the blockchain. The records are utilized as attributes for authorization and as proofs of incentive plans. This approach incorporates the preferences of participating platforms and end users, and opens new avenues for collaborative edge computing as well as research on blockchain-based access control mechanism for IoT environments.

TL;DR: This article proposes a fog-computing- enabled cognitive network functions virtualization approach for an information-centric future Internet, and proposes an on-demand caching function virtualization scheme and a communication scheme between the fog nodes and the future Internet nodes for the forwarding process.
Abstract: Information-centric networking (ICN) is an important trend that will impact the future of the Internet. ICN caters to large content consumption patterns while achieving high performance. New features in the information-centric future Internet, such as caching, name-based routing, and content-based security, bring novel challenges to a decentralized environment. On one hand, the processing capabilities on the edge in an information-centric future Internet need to implement smart analysis for large quantities of content. On the other hand, the computational and storage resources need to be configured and controlled on demand and based on cognition of the content from users. To address these challenges, this article proposes a fog-computing- enabled cognitive network functions virtualization approach for an information-centric future Internet. We first propose an on-demand caching function virtualization scheme and design a communication scheme between the fog nodes and the future Internet nodes for the forwarding process. Then, to attain smart control for related operations (i.e., routing, cache policy, and security), we propose a control function virtualization approach. Finally, a cognitive resource configuration mechanism is proposed. The simulation results show the advantages and efficiency of the proposed approach.
