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...

Access-Time-Aware Cache Algorithms
Giovanni Neglia, Damiano Carra, Mingdong Feng, Vaishnav Janardhan, Pietro Michiardi, Dimitra Tsigkari
Article No.: 21
DOI: 10.1145/3149001

Most of the caching algorithms are oblivious to requests’ timescale, but caching systems are capacity constrained and, in practical cases, the hit rate may be limited by the cache’s impossibility to serve requests fast enough. In...
