A Novel Fog Computing Approach for Minimization of Latency in Healthcare using Machine Learning
In the recent scenario, the most challenging requirements are to handle the massive generation of multimedia data from the Internet of Things (IoT) devices which becomes very difficult to handle only through the cloud. Fog computing technology emerges as an intelligent solution and uses a distributed environment to operate. The objective of the paper is latency minimization in e-healthcare through fog computing. Therefore, in IoT multimedia data transmission, the parameters such as transmission delay, network delay, and computation delay must be reduced as there is a high demand for healthcare multimedia analytics. Fog computing provides processing, storage, and analyze the data nearer to IoT and end-users to overcome the latency. In this paper, the novel Intelligent Multimedia Data Segregation (IMDS) scheme using Machine learning (k-fold random forest) is proposed in the fog computing environment that segregates the multimedia data and the model used to calculate total latency (transmission, computation, and network). With the simulated results, we achieved 92% as the classification accuracy of the model, an approximately 95% reduction in latency as compared with the pre-existing model, and improved the quality of services in e-healthcare
A Fast and Scalable Authentication Scheme in IoT for Smart Living
Numerous resource-limited smart objects (SOs) such as sensors and actuators
have been widely deployed in smart environments, opening new attack surfaces to
intruders. The severe security flaw discourages the adoption of the Internet of
things in smart living. In this paper, we leverage fog computing and
microservice to push certificate authority (CA) functions to the proximity of
data sources. Through which, we can minimize attack surfaces and authentication
latency, and result in a fast and scalable scheme in authenticating a large
volume of resource-limited devices. Then, we design lightweight protocols to
implement the scheme, where both a high level of security and low computation
workloads on SO (no bilinear pairing requirement on the client-side) is
accomplished. Evaluations demonstrate the efficiency and effectiveness of our
scheme in handling authentication and registration for a large number of nodes,
meanwhile protecting them against various threats to smart living. Finally, we
showcase the success of computing intelligence movement towards data sources in
handling complicated services.Comment: 15 pages, 7 figures, 3 tables, to appear in FGC
Integrating Blockchain and Fog Computing Technologies for Efficient Privacy-preserving Systems
This PhD dissertation concludes a three-year long research journey on the integration of Fog Computing and Blockchain technologies. The main aim of such integration is to address the challenges of each of these technologies, by integrating it with the other. Blockchain technology (BC) is a distributed ledger technology in the form of a distributed transactional database, secured by cryptography, and governed by a consensus mechanism. It was initially proposed for decentralized cryptocurrency applications with practically proven high robustness. Fog Computing (FC) is a geographically distributed computing architecture, in which various heterogeneous devices at the edge of network are ubiquitously connected to collaboratively provide elastic computation services. FC provides enhanced services closer to end-users in terms of time, energy, and network load. The integration of FC with BC can result in more efficient services, in terms of latency and privacy, mostly required by Internet of Things systems
