A Blockchain Policy and Charging Control Framework for Roaming in Cellular Networks
As a technology foundation of cryptocurrencies, blockchain enables
decentralized peer-to-peer trading through consensus mechanisms without the
involvement of a third party. Blockchain has been regarded as an auspicious
technology for future cellular networks. It is able to provide solutions to
problems related to mobile operators and user trust, embedded smart contracts,
security concerns, pricing (e.g. for roaming), etc. When applying blockchain to
cellular networks, there are significant challenges in terms of deployment and
application, due to resource-constrained transactions. This article begins by
introducing the basic concept of blockchain and then moves on to illustrate its
benefits and limitations in the roaming system. Two models of roaming-based
blockchain technologies are offered to show their suitability for cellular
networks as opposed to traditional technology. Finally, potential issues and
challenges of roaming-based blockchains are addressed and evaluated using the
roaming use case in the EU
A Blockchain Framework for Secure Task Sharing in Multi-access Edge Computing
In the context of Multi-access Edge Computing (MEC), the task sharing
mechanism among edge servers is an activity of vital importance for speeding up
the computing process and thereby improve user experience. The distributed
resources in the form of edge servers are expected to collaborate with each
other in order to boost overall performance of a MEC system. However, there are
many challenges to adopt global collaboration among the edge computing server
entities among which the following two are significant: ensuring trust among
the servers and developing a unified scheme to enable real-time collaboration
and task sharing. In this article, a blockchain framework is proposed to
provide a trusted collaboration mechanism between edge servers in a MEC
environment. In particular, a permissioned blockchain scheme is investigated to
support a trusted design that also provides incentives for collaboration.
Finally, Caliper tool and Hyperledger Fabric benchmarks are used to conduct an
experimental evaluation of the proposed blockchain scheme embedded in a MEC
framework
