Adding flexibility to multi-tenant networks

Georgios Ioannidis

Cloud computing has been experiencing sharp development over the last years, leading to an increased demand for application migration to the cloud. Cloud providers, in an effort to attract more customers and earn their confidence, offer to tenants the illu ...

Extending database task schedulers for multi-threaded application code

Anastasia Ailamaki, Iraklis Psaroudakis

Modern databases can run application logic defined in stored procedures inside the database server to improve application speed. The SQL standard specifies how to call external stored routines implemented in programming languages, such as C, C++, or JAVA, ...

EYEDIAP Database: Data Description and Gaze Tracking Evaluation Benchmarks

Jean-Marc Odobez, Florent Monay Michaud, Kenneth Alberto Funes Mora

The lack of a common benchmark for the evaluation of the gaze estimation task from RGB and RGB-D data is a serious limitation for distinguishing the advantages and disadvantages of the many proposed algorithms found in the literature. The EYEDIAP database ...

Interactive Free Viewpoint Video Streaming Using Prioritized Network Coding

Pascal Frossard, Nikolaos Thomos, Laura Toni

In free viewpoint applications, the images are cap- tured by an array of cameras that acquire a scene of interest from different perspectives. Any intermediate viewpoint not included in the camera array can be virtually synthesized by the decoder, at a qua ...

Evaluation of Accelerometer-Based Fall Detection Algorithms on Real-World Falls

Kamiar Aminian

Despite extensive preventive efforts, falls continue to be a major source of morbidity and mortality among elders. Real-time detection of falls and their urgent communication to a telecare center may enable rapid medical assistance, thus increasing the sen ...

Distributed Rate Allocation With Intersession Network Coding

Pascal Frossard, Nikolaos Thomos, Eirina Bourtsoulatze

In this paper, we propose a distributed rate allocation algorithm for delay minimal data delivery in overlay networks where multiple sources compete simultaneously for the available network resources. In order to efficiently utilize the network resources, ...

Signaling and Reciprocity

Wojciech Galuba

Complex networks exist for a number of purposes. The neural, metabolic and food networks ensure our survival, while the social, economic, transportation and communication networks allow us to prosper. Independently of the purposes and particularities of th ...

Self-organized fault-tolerant routing in peer-to-peer overlays

Karl Aberer, Wojciech Galuba, Zoran Despotovic

In sufficiently large heterogeneous overlays message loss and delays are likely to occur. This has a significant impact on overlay routing, especially on longer paths. The existing solutions to this problem rely on message redundancy to mask the loss and d ...

Delay-based overlay construction in P2P video broadcast

Pascal Frossard

We consider streaming video content over an overlay network of peer nodes. Each of the nodes employs a mesh-pull mechanism to organize the download of data units from its neighbours. We propose a novel algorithm for constructing the distribution overlay, w ...

Utility-based Packet Scheduling in P2P Mesh-based Multicast

Pascal Frossard

We consider streaming video content over an overlay network of peer nodes. We propose a novel streaming strategy that is built on utility-based packet scheduling and proportional resource sharing in order to fight against free- riders. Each of the peers em ...
