METHOD FOR LOCATING WIRELESS NODES USING DIFFERENCE TRIANGULATION

摘要

PURPOSE: A wireless node locating method using differential trigonometry is provided to remove the need for preliminary location management of fixed wireless nodes because a mobile wireless node accumulates and processes data of received signal strength from the fixed wireless nodes to estimate the location points of the individual fixed wireless nodes. CONSTITUTION: A mobile wireless node stores information transmitted from three or more fixed wireless nodes while moving on a specific path(S401), computes displacement vectors between three or more measuring points(S402), produces the location information of the mobile wireless node at another measuring point(S403), and produces the location information of a fixed wireless node whose location is unknown(S404).
