A blockchain-based architecture for secure IoT-based health monitoring systems

Although IoT technology brings significant benefits to the healthcare sector and can play a noteworthy role in improving citizens’ quality of life by enabling IoT-based health monitoring systems, it also raises many security challenges. Conventional security mechanisms are inadequate to secure IoT-based health monitoring systems as they have high resource requirements, in terms of computational power and energy consumption, and thus they cannot be afforded by the resource-constrained IoT nodes of these systems. On the other hand, blockchain is a promising technology that can be used to enhance the security of IoT-based health monitoring systems due to its decentralized and autonomous nature. Therefore, in this paper, we propose a blockchain architecture, based on the Hyperledger Fabric platform, for securing IoTbased health monitoring systems in a more lightweight manner as Hyperledger Fabric does not apply the consensus protocol of Proof of Work (PoW) that cannot be afforded by IoT devices

The Many Faces of Edge Intelligence

Edge Intelligence (EI) is an emerging computing and communication paradigm that enables Artificial Intelligence (AI) functionality at the network edge. In this article, we highlight EI as an emerging and important field of research, discuss the state of research, analyze research gaps and highlight important research challenges with the objective of serving as a catalyst for research and innovation in this emerging area. We take a multidisciplinary view to reflect on the current research in AI, edge computing, and communication technologies, and we analyze how EI reflects on existing research in these fields. We also introduce representative examples of application areas that benefit from, or even demand the use of EI.Peer reviewe

5G Media slice definition

This document is the outcome of a joined working group setup between the two European Technology Platforms, New European Media (NEM) and Networld2020. The objective was to combine expertise from the media sector which brought application requirements and the network domain which brought expertise in 5G. Nine media&content use cases have been identified by the group that cover most of the common media&content situations from production to consumption. From these 9 use cases the group has identified 12 parameters that should be used to adapt the network to the application requirements, such as: Latency, Reliability, Data rate, Mobility, User density, Positioning, User Equipment speed. Looking to the 5G network capabilities and parameters that could be activated, the last section provides a description of 5G Media Slices. There is a “s” because one of the main conclusions of the paper is that the media chain encompasses a number of functionalities and operations such as content creation, service composition, service aggregation, content distribution, devices, user interaction and interfaces, which requires different slices. Additionally, 5G requirements will be different for production which needs mostly uplink capacities and distribution which needs mostly downlink capacities. For each of the 9 use cases, there is a proposal to allocate 1 or 2 slices, detailed in the conclusion of this paper. The objective of this paper is to provide proposals and reference material to standardisation organisations in order to contribute to the design and specification of 5G Media Slices
