Abstract :
One of the most interesting applications of sensor networks is the localization and tracking of moving objects. The cricket location-support system (CLS), originally developed at MIT and now distributed by Crossbow Technologies, tracks a moving object using time-difference-of-arrival (TDOA) between radio frequency (RF) and ultrasonic signals. In this work we evaluate the ability of CLS to track people with various levels of mobility within a 2-dimensional space. The results presented here are preliminary results in a larger effort to determine whether or not CLS can be used to track people in a smart assistive technology living space
