Wireless localization method based on an efficient multilateration algorithm over a wireless sensor network and a recording medium in which a program for the method is recorded

摘要

The wireless positioning technology with a wireless sensor network on efficient multivariate measurement is started. At least three reference nodes, and using the received signal strength (RSS) of the radio reception signal received from the blind node calculates the estimated distance to each blind node from the reference node, using a multivariate the calculated estimated distance measurement ( multilateration) to calculate the estimated position of the blind node. For error correction included in the estimated position, and using the calculated estimated distance, but by applying the largest weight to the nearest node to the estimated location is calculated based on the error correction direction and distance of the estimated position error correction. Error correction by error correction movement direction and distance of calculating the presumed location of the blind node calculated by correcting the error in the estimated position. The error correction of the estimated position by using only a simple calculation to estimate the distance and rapid error correction is possible, and thus can be applied to the real-time location services. ;
