SAMR: A Self-adaptive MapReduce Scheduling Algorithm in Heterogeneous Environment
TLDR
This work proposes SAMR: a Self-Adaptive MapReduce scheduling algorithm, which calculates progress of tasks dynamically and adapts to the continuously varying environment automatically, and significantly decreases the time of execution. Expand
Efficient Algorithms for Capacitated Cloudlet Placements
TLDR
This paper studies the cloudlet placement problem in a large-scale Wireless Metropolitan Area Network (WMAN) consisting of many wireless Access Points (APs) with the objective to minimize the average access delay between mobile users and the cloudlets serving the users. Expand
Joint Optimization of Task Scheduling and Image Placement in Fog Computing Supported Software-Defined Embedded System
TLDR
A computation-efficient solution is proposed based on the formulation and validated by extensive simulation based studies to deal with the high computation complexity of fog computing supported software-defined embedded system. Expand
Cost Efficient Resource Management in Fog Computing Supported Medical Cyber-Physical System
TLDR
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. Expand
Can We Beat DDoS Attacks in Clouds?
TLDR
This paper proposes a dynamic resource allocation strategy to counter DDoS attacks against individual cloud customers and establishes a mathematical model to approximate the needs of the resource investment based on queueing theory. Expand
Discriminating DDoS Attacks from Flash Crowds Using Flow Correlation Coefficient
TLDR
A discrimination algorithm using the flow correlation coefficient as a similarity metric among suspicious flows is proposed using the size and organization of current botnets and demonstrated the effectiveness of the proposed method in practice. Expand
Evolution of Software-Defined Sensor Networks
TLDR
The concept of software-defined sensor networks (SDSNs) is introduced and several pioneering related work and enabling technologies for the realization of SDSNs are outlined. Expand
Protection of Big Data Privacy
TLDR
The infrastructure of big data and the state-of-the-art privacy-preserving mechanisms in each stage of the big data life cycle are illustrated and the challenges for existing mechanisms are presented. Expand
Energy-aware multicasting in wireless ad hoc networks: A survey and discussion
TLDR
A systematical investigation of current state-of-the-art algorithms for the energy-aware multicast routing problem and the MLB/MLM problem in wireless ad hoc networks with omni-directional and directional antennas is presented. Expand
Software-defined wireless mesh networks: architecture and traffic orchestration
TLDR
This article first proposes a novel architecture of SD-WMNs, and identifies several critical challenges, and proposes three spectrum allocation and scheduling algorithms, namely FB-NS, NFB- NS, and N FB-S that orchestrate both control and data traffic. Expand
