Bargaining Game-Based Scheduling for Performance Guarantees in Cloud Computing
Chubo Liu, Kenli Li, Zhuo Tang, Keqin Li
Article No.: 1
DOI: 10.1145/3141233

In this article, we focus on request scheduling with performance guarantees of all users in cloud computing. Each cloud user submits requests with average response time requirement, and the cloud provider tries to find a scheduling scheme, i.e.,...

Selecting the Top-Quality Item Through Crowd Scoring
Alessandro Nordio, Alberto Tarable, Emilio Leonardi, Marco Ajmone Marsan
Article No.: 2
DOI: 10.1145/3157736

We investigate crowdsourcing algorithms for finding the top-quality item within a large collection of objects with unknown intrinsic quality values. This is an important problem with many relevant applications, such as in networked recommendation...

Mean-Field Analysis of Coding Versus Replication in Large Data Storage Systems
Bin Li, Aditya Ramamoorthy, R. Srikant
Article No.: 3
DOI: 10.1145/3159172

We study cloud storage systems with a very large number of files stored in a very large number of servers. In such systems, files are either replicated or coded to ensure reliability, i.e., to guarantee file recovery from server failures. This...

EQ: A QoE-Centric Rate Control Mechanism for VoIP Calls
Cing-Yu Chu, Shannon Chen, Yu-Chuan Yen, Su-Ling Yeh, Hao-Hua Chu, Polly Huang
Article No.: 4
DOI: 10.1145/3170430

The rising popularity of data calls and the slowed global economy have posed a challenge to voice data networking—how to satisfy the growing user demand for VoIP calls under limited network resources. In a bandwidth-constrained network in...

An Online Emergency Demand Response Mechanism for Cloud Computing
Ruiting Zhou, Zongpeng Li, Chuan Wu
Article No.: 5
DOI: 10.1145/3177755

This article studies emergency demand response (EDR) mechanisms from a data center perspective, where a cloud participates in a mandatory EDR program while receiving computing job bids from cloud users in an online fashion. We target a realistic...
