ABSTRACT
Temporal dependencies between multiple sensor data sources link two types of events if the occurrence of one is repeatedly followed by the appearance of the other in a certain time interval. TEDDY algorithm aims at discovering such dependencies, identifying the statically significant time intervals with a chi2 test. We present how these dependencies can be used within the GrizzLY project to tackle an environmental and technical issue: the deicing of the roads. This project aims to wisely organize the deicing operations of an urban area, based on several sensor network measures of local atmospheric phenomena. A spatial and temporal dependency-based model is built from these data to predict freezing alerts.

When Transportation Meets Communication: V2P over VANETs
ICDCS '10: Proceedings of the 2010 IEEE 30th International Conference on Distributed Computing SystemsInformation interaction is a crucial part of modern transportation activities. In this paper, we propose the idea of Vehicle-to-Passenger communication (V2P), which allows direct, instant, and flexible communication between moving vehicles and roadside ...
TinyOS meets wireless mesh networks
SenSys '10: Proceedings of the 8th ACM Conference on Embedded Networked Sensor SystemsWe present TinyWifi, a nesC code base extending TinyOS to support Linux powered network nodes. It enables developers to build arbitrary TinyOS applications and protocols and execute them directly on Linux by compiling for the new TinyWifi platform. ...
Compressive sensing meets unreliable link: sparsest random scheduling for compressive data gathering in lossy WSNs
MobiHoc '14: Proceedings of the 15th ACM international symposium on Mobile ad hoc networking and computingCompressive Sensing (CS) has been recognized as a promising technique to reduce and balance the transmission cost in wireless sensor networks (WSNs). Existing efforts mainly focus on applying CS to reliable WSNs, namely, each wireless link is 100% ...
