AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Existing position-based unicast routing algorithms which forward packets in the geographic direction of the destination require that the forwarding node knows the positions of all neighbors in its transmission range. This information on direct neighbors is ...

We consider the problem of low-complexity channel estimation and timing in digital ultra-wideband receivers. We extend some of our recent results on sampling of certain classes of parametric non-bandlimited signals and develop a frequency domain framework ...
We derive performance expressions for the throughput and blocking probability for a class of wireless networks with a clustering protocol. The nodes are assumed stationary and establish connections with the master node according to a priority scheme that r ...
The Terminode project follows a system approach to investigate wide area, large, totally wireless networks that we call mobile ad-hoc wide area networks. A netw ork of terminodes is an autonomous, self-operated, wireless multimedia network, independent of ...
This paper presents the results of our quality evaluations of video sequences encoded for and transmitted over a wireless channel. We selected content, codecs, bitrates and bit error patterns representative of mobile applications and we concentrated on the ...
There is an important trend toward personal mobile communications. People use more and more handheld devices to keep in touch with friends or business partners. One possible way to connect these devices is provided by wireless radio technologies. The emerg ...

We consider the problem of low-sampling rate high-resolution channel estimation and timing for digital ultra-wideband (UWB) receivers. We extend some of our recent results in sampling of certain classes of parametric non-bandlimited signals and develop a f ...
Method for performing electronic payments between a mobile equipment and a payment terminal over a short distance wireless interface, comprising displaying an identification (for example T; T-id) on the display (110) of said payment terminal (11), manually ...
