Multiobjective Optimization for Computation Offloading in Fog Computing
TL;DR: In this article, the authors utilized queuing theory to bring a thorough study on the energy consumption, execution delay, and payment cost of offloading processes in a fog computing system, where three queuing models were applied, respectively, to the MD, fog, and cloud centers, and the data rate and power consumption of the wireless link were explicitly considered.
Journal ArticleDOI
Socially Aware Dynamic Computation Offloading Scheme for Fog Computing System With Energy Harvesting Devices
TL;DR: This paper takes the social relationships of the EH mobile devices (MDs) into the design of computational off loading scheme in fog computing and proposes a dynamic computation offloading scheme designing the offloading process in fog Computing system with EH MDs to minimize the social group execution cost.
Journal ArticleDOI
Dynamic Resource Allocation and Computation Offloading for IoT Fog Computing System
TL;DR: A dynamic optimization scheme for the IoT fog computing system with multiple mobile devices (MDs), where the radio and computational resources, and offloading decisions, can be dynamically coordinated and allocated with the variation of radio resources and computation demands is proposed.
Journal ArticleDOI
Data offloading and task allocation for cloudlet-assisted ad hoc mobile clouds
TL;DR: A data offloading and task allocation scheme for a cloudlet-assisted ad hoc mobile cloud in which the master device who has computational tasks can access resources from nearby slave devices or the cloudlet, instead of the centralized cloud, to share the workload, in order to reduce the energy consumption and computational cost.
Proceedings ArticleDOI
Multi-objective optimization for computation offloading in mobile-edge computing
TL;DR: In this article, a multi-objective optimization problem is formulated with the joint objectives to minimize the energy consumption, execution delay and price cost by finding the optimal offloading probability and optimal transmission power for each mobile device.
