title = "Analyzing Error Propagation in Range-based Multihop Sensor Localization",
abstract = "Location information for sensors in wireless sensor networks (WSNs) is essential to many tasks. If sensors are mobile and are to be controlled to certain locations, localizability is indispensable. In a noisy environment, locations must be estimated, and the question of location error and its magnitude becomes important. Error is a function of the positioning and density of anchors in a WSN, and the error can propagate (i.e. increase) as sensors progressively more distant from anchors are localized. Understanding the semi-quantitative rules governing error propagation is quite helpful to designing WSNs and improving performances of localization systems. This paper deals with error propagation in 1-Dimensional WSNs with noisy range measurements in terms of the Cram{\'e}r-Rao Lower Bound. Factors influencing error propagation are investigated carefully, and a divide and conquer method is presented to analyze error propagation in WSNs.",
