Abstract :
Wireless Sensor Networks have attracted mutch interest in the last decade, opening a new range of applications such as large area monitoring. However, a range of possible applications is still not satisfied due to strong blocking points remaining unsolved such as the lack of synchronization between measurements and low attain- able data rates. This doctoral work aims at solving these two issues issue through the design of a Wireless Sensor node implementation. The proposed solution is based on cross-layer design and uses time-domain properties of UltraWide Band (UWB) to provide nanosecond-scale synchronization between nodes and high data- rate transmission. An ASIC implementation has been designed, and demonstrates a 2 ns synchronization error with IR-UWB modulation over a 1.5 GHz bandwidth. In this thesis, a cross-layer scheme named WiDeCS is proposed, and two proof of concept implementations are detailed.
