Développement et analyse multi outils d'un protocole MAC déterministe pour un réseau de capteurs sans fil

In this article, we present a multi-tool method for the development and the analysis of a new medium access method. IEEE 802.15.4 / ZigBee technology has been used as a basis for this new determinist MAC layer which enables a high level of QoS. This WPAN can be typically used for wireless sensor networks which require strong temporal constraints. To validate the proposed protocol, three complem...

Information Elicitation Sans Verification

The recent advent of human computation — employing groups of non-experts to solve problems — has motivated study of a question in mechanism design: How do we elicit useful information when we are unable to verify reports? Existing methods, such as peer prediction and Bayesian truth serum, require assumptions either on the mechanism’s knowledge about the participants or on the information struct...
