A Study of Localization Metrics: Evaluation of Position Errors in Wireless Sensor Networks [PDF]

open access: yes, 2011
For wireless sensor network applications that require location information for sensor nodes, locations of nodes can be estimated by a number of localization algorithms, which inevitably may introduce various types of errors in their estimations.
