Energy Efficiency in Wireless Sensor Networks: A Utility-Based Architecture

Ioannis Alagiannis, Manoussos Gavriil Athanassoulis

Wireless Sensor Networks (WSN) comprise a fast developing research area with a vast spectrum of applications. A WSN design is influenced by many factors such as transmission errors, network topology and power consumption. Consequently, developing a WSN app ...

Advances in indoor Location

Phillip Tomé

This paper presents the research activities carried out within the scope of the Liaison project. Most of the work has been performed on WiFi location. WiFi is nowadays widely deployed in buildings such as hotels, hospitals, airports, train stations, public ...

The Virtue of Patience when Scheduling Media in Presence of Feedback

Pascal Frossard, Christophe De Vleeschouwer

We consider streaming of pre-encoded and packetized media over best-effort networks in presence of acknowledgment feedback. Given an estimation of future transmission resources and knowing about past transmissions and received acknowledgments, a scheduling ...

Packetized Media Streaming with Comprehensive Exploitation of Feedback Information

Pascal Frossard, Christophe De Vleeschouwer

This paper addresses the problem of streaming packetized media over a lossy packet network, with sender-driven (re)transmission using acknowledgement feedback. The different transmission scenarios associated to a group of interdependent media data units ar ...

The virtue of patience in low complexity scheduling of packetized media with feedback

Pascal Frossard, Christophe De Vleeschouwer

We consider streaming of pre-encoded and packetized media over best-effort networks in presence of acknowledgment feedbacks. We first review the rate-distortion optimization framework in such scenarios. Given an estimation of future transmission resources, ...

Achievable Diversity-Multiplexing-Delay Tradeoff in Half-Duplex ARQ Relay Channels

Sanket Dusad

In this paper, we present an efficient protocol for the delay-limited fading Automatic Retransmission reQuest single relay channel. The source is using an ARQ retransmission protocol to send data to the relay and the destination. When the relay is able to ...

Extremum feedback with partial knowledge

Jörg Widmer

A scalable feedback mechanism to solicit feedback from a potentially very large group of networked nodes is an important building block for many network protocols. Multicast transport protocols use it for negative acknowledgements and for delay and packet ...

Preferential Treatment of Acknowledgment Packets in a Differentiated Services Network

Patrick Thiran

In the context of Differentiated Services (DiffServ), we investigate the effect of acknowledgment marking on the throughput of TCP connections. We carry out experiments on a testbed offering three classes of service (Premium, Assured and Best-Effort), and ...

Adaptive Delay Aware Error Control for Internet Telephony

Jean-Yves Le Boudec, Catherine Boutremans

Forward Error Correction copes with packet losses, but at the expense of an increase of the end-to-end delay. By failing to take this into account, existing error control schemes for audio often lead to end-to-end delays larger than 150 ms, which has an im ...
