Location Fingerprint System Based on TOA
|
Abstract:
How to set up a low-cost,high-accuracy real-time location system based on wireless sensor network is one of the popular research topics.This paper,according to our analysis on various sets of experimental data, suggests that current wireless chips are not suitable for location fingerprinting based on RSS.In addition,a new location fingerprint system based on TOA is proposed.It regards distances from TOA as reference signals and makes use of wireless signal's continuity to improve the location accuracy.The e...
