Let C denote a set of n mobile clients, each of which follows a continuous trajectory on a weighted tree T. We establish tight bounds on the maximum relative velocity of the 1-cent...
This paper presents algorithms, simulations, and empirical results of a system that finds relative tag positions in 3D space using a new approach called “mobile infrastructure....
The engineering community has recently begun to adopt wireless sensing technologies for use in many sensing applications. These low-cost sensors provide an optimal setting for den...
