The Economics of the Cloud
Jonatha Anselmi, Danilo Ardagna, John C. S. Lui, Adam Wierman, Yunjian Xu, Zichao Yang
Article No.: 18
DOI: 10.1145/3086574

This article proposes a model to study the interaction of price competition and congestion in the cloud computing marketplace. Specifically, we propose a three-tier market model that captures a marketplace with users purchasing services from...

Resource Auto-Scaling and Sparse Content Replication for Video Storage Systems
Di Niu, Hong Xu, Baochun Li
Article No.: 19
DOI: 10.1145/3079045

Many video-on-demand (VoD) providers are relying on public cloud providers for video storage, access, and streaming services. In this article, we investigate how a VoD provider may make optimal bandwidth reservations from a cloud service provider...

Behavioral Model of IEEE 802.15.4 Beacon-Enabled Mode Based on Colored Petri Net
Renan C. A. Alves, Cíntia B. Margi
Article No.: 20
DOI: 10.1145/3115389

The IEEE 802.15.4 standard is widely employed in power-constrained scenarios, such as Wireless Sensor Networks deployments. Therefore, modeling this standard is useful to predict network performance and fine-tune parameter settings. Previous work...
