Cost Efficient Resource Management in Fog Computing Supported Medical Cyber-Physical System
TL;DR: Fog computation and MCPS are integrated to build fog computing supported MCPS (FC-MCPS), and an LP-based two-phase heuristic algorithm is proposed that produces near optimal solution and significantly outperforms a greedy algorithm.
Journal ArticleDOI
UAV assistance paradigm: State-of-the-art in applications and challenges
Bander A. Alzahrani,Omar Sami Oubbati,Ahmed Barnawi,Mohammed Atiquzzaman,Daniyal M. Alghazzawi +4 more
TL;DR: This comprehensive survey both studies and summarizes the existing UAV-assisted research, such as routing, data gathering, cellular communications, Internet of Things (IoT) networks, and disaster management that supports existing enabling technologies.
Smart Items, Fog and Cloud Computing as Enablers of Servitization in Healthcare
TL;DR: It is argued that smart items and cloud computing can be powerful enablers of servitization as business trend and presented a three-level architecture for a smart healthcare infrastructure based on a service-oriented architecture and extends established architectural approaches developed previously at the group.
Journal ArticleDOI
Malware Propagation in Large-Scale Networks
TL;DR: A rigorous two layer epidemic model for malware propagation from network to network is established, and analysis indicates that the distribution of a given malware follows exponential distribution, power law distribution with a short exponential tail, and powerLaw distribution at its early, late and final stages, respectively.
Journal ArticleDOI
