A computation offloading method over big data for IoT-enabled cloud-edge computing
TL;DR: A system model and dynamic schedules of data/control-constrained computing tasks are investigated, including the execution time and energy consumption for mobile devices, and NSGA-III (non-dominated sorting genetic algorithm III) is employed to address the multi-objective optimization problem of task offloading in cloud-edge computing.
Journal ArticleDOI
A Blockchain-Powered Crowdsourcing Method With Privacy Preservation in Mobile Environment
TL;DR: A mobile crowdsourcing framework based on blockchain is designed first to preserve the privacy of the participants and keep the integrity of the service request and provision, and then density-based spatial clustering of applications with noise and improved dynamic programming are adopted to cluster the requestors and generate service strategies, respectively.

Journal ArticleDOI
A blockchain-based computation offloading method for edge computing in 5G networks
TL;DR: A blockchain‐based computation offloading method, named BCO, which is designed to degrade the data loss possibility by integrating blockchain and EC, and takes advantage of Simple Additive Weighting and Multiple Criteria Decision Making to identify the optimal offloading strategy.
Proceedings ArticleDOI
A Heuristic Virtual Machine Scheduling Method for Load Balancing in Fog-Cloud Computing
TL;DR: A heuristic VM scheduling method is designed through VM placement and dynamic VM scheduling by leveraging the VM live migration technique to realize the load balancing for the computing nodes in the fog-cloud environment.
