Abstract-We investigate the relation between medium access control (MAC) delay and ultra-wide bandwidth (UWB) tracking accuracy. We quantify this relation by deriving fundamental lower bounds on tracking accuracy and MAC delay for arbitrary finite networks. Our main finding is that the traditional ways to increase accuracy (e.g., increasing the number of anchors or the transmission power) may lead to large MAC delays. We evaluate two methods to mitigate these delays.
In REF , they focus on the relation between MAC delay and UWB accuracy related to the number of anchors and the communication range of nodes under mobility.
