Optimal cooperative content placement algorithms in hierarchical cache topologies
(2012)
The tremendous growth in the use of the World Wide Web and the expansion of Video On Demand and IPTV services increase the bandwidth demands, enforcing the creation of congestion in Internet's links and the experience of ...
Multicast-aware caching for small cell networks
(2014)
The deployment of small cells is expected to gain huge momentum in the near future, as a solution for managing the skyrocketing mobile data demand growth. Local caching of popular files at the small cell base stations has ...
Video delivery over heterogeneous cellular networks: Optimizing cost and performance
(2014)
Video delivery to mobile users is one of the largest challenges that network operators face today. In this work we consider a heterogeneous cellular network with storage capable small-cell base stations, and study this ...
Optimal algorithms for hierarchical web caches
(2013)
Hierarchical topologies have been applied in many existing systems that provide public IPTV or massive content delivery services. The efficient operation of these services requires massive bandwidth resources. Data caching ...
Surviving in a competitive market of information providers
(2013)
As the processing and transport capacity of the information and communication technologies (ICT) infrastructure increased vastly the last few years, the bottleneck of the information exchange process moved to the end points ...
Exploiting user mobility for wireless content delivery
(2013)
We consider the problem of storing segments of encoded versions of content files in a set of base stations located in a communication cell. These base stations work in conjunction with the main base station of the cell. ...
Approximation Algorithms for Mobile Data Caching in Small Cell Networks
(2014)
Small cells constitute a promising solution for managing the mobile data growth that has overwhelmed network operators. Local caching of popular content items at the small cell base stations (SBSs) has been proposed to ...
Optimal selfishness-aware device-assisted content delivery in cellular networks
(2014)
Utilization of device-to-device communication links provides an alternative way for mitigating the skyrocketing mobile data growth that challenges cellular operators nowadays. Namely, the owners of these devices can serve ...
Pricing the last mile: Data capping for residential broadband
(2014)
In recent years, ISPs in mature residential broadband markets have been moving away from flat-rate pricing schemes to ones that involve usage limits (or ?data caps). These changes have led to a lively debate about the ...
A framework for mobile data offloading to leased cache-endowed small cell networks
(2015)
Cache-endowed small cell networks constitute a timely and effective solution for mobile network operators (MNOs) who strive to serve the massive content demand of the mobile users. However, the deployment of small cell ...
