Computation Offloading and Resource Allocation in Mixed Fog/Cloud Computing Systems With Min-Max Fairness Guarantee
TL;DR: This paper tackles the computation offloading problem in a mixed fog/cloud system by jointly optimizing the offloading decisions and the allocation of computation resource, transmit power, and radio bandwidth while guaranteeing user fairness and maximum tolerable delay.
Journal ArticleDOI
An Integrated Architecture for Software Defined and Virtualized Radio Access Networks with Fog Computing
TL;DR: This article proposes a design of software as a service called OpenPipe, which enables network-level virtualization and adopts a hybrid control model with two hierarchical control levels, where an SDN controller forms the higher level and local controllers comprise the lower level.
Journal ArticleDOI
Enabling Low-Latency Applications in LTE-A Based Mixed Fog/Cloud Computing Systems
TL;DR: A low-complexity iterative suboptimal algorithm called BTFA based joint computation offloading and resource allocation algorithm (FAJORA) is proposed to solve the computation offload problem in a mixed fog and cloud computing system.
Journal ArticleDOI
A Rear-End Collision Risk Evaluation and Control Scheme Using a Bayesian Network Model
TL;DR: Numerical results show that the proposed model provides an accurate estimation for car-following collision risk with a relatively low complexity, taking into account the impacts of vehicle dynamics, driver reaction capacity, and external environment on rear-end collisions.
Journal ArticleDOI
Energy Harvesting Enabled NOMA Systems With Full-Duplex Relaying
TL;DR: This paper investigates an integrated wireless communication system including non-orthogonal multiple access, full-duplex relaying, and energy harvesting techniques (named as EH-FD-NOMA), and numerical results show the superior performance of the EH, if compared to its counterparts.
