Abstract(s) :

(Anglais) The 2007 amendment of the IEEE 802.15.4 standard [1] includes an Ultrawide Band (UWB) physical layer. It relies on spreading the RF energy over more than 500 MHz with the advantage of high resilience to multi-path propagation and precise time of arrival estimation. A major drawback of UWB is the lack of standard MAC layer. In this paper, we present UWB-TSCH, an adaptation of the Time Slotted Channel Hopping (TSCH) MAC layer design for UWB. This approach combines time division medium access with frequency hopping. This allows for UWB nodes to reach much higher channel occupancy than with Aloha and to drastically reduce their energy consumption, allowing them to be used in low power wireless sensor networks. Moreover, we show that using multiple channels concurrently, localization schemes such as Time Difference of Arrival (TDoA) could reach in excess of 2400 localizations per second.
