An intuitive prioritised medium access scheme for tracking applications in UWB LDR-LT networks

In this paper, we describe an adaption of prioritised medium access techniques for high-precision real-time tracking applications in ultra wideband (UWB) low data rate (LDR) wireless networks. In comparison with classical time division multiple access (TDMA) schemes, the proposed uncoordinated distributed prioritised solution is compliant with critical tracking requirements in large-scale networks. More particularly, the described protocol tends to favor high-speed targets as regards to the success rate of ranging packets issued at anchor nodes, as well as to the refreshment rate and the precision of range measurements. Finally, the performance of this solution is evaluated in comparison with TDMA schemes.
