Abstract: This paper presents a deployment methodology for sensor field localization systems. To deploy our ultrasound based localization system, we first create a simulation environment that captures real-world ranging characteristics. The localization system can then be designed against the ranging noise of a particular environment and ranging implementation. The simulation environment can also be used to estimate the localization accuracy and probability of successful localization before the deployment actually takes place. We evaluate this methodology through the empirical deployment in a 49 node, 8 hop network in which the system achieves an average accuracy of about 50cm.
