Method and apparatus for determining the location of a node in a wireless network
First Claim
1. A method for determining a location of a node in a wireless network, the method comprising the steps of:
- receiving a plurality of signals from located nodes;
determining a plurality of signal strengths for the plurality of signals;
correcting the plurality of signal strengths based on at least one radiation pattern; and
locating the node based on the corrected signal strengths.

Abstract
A method and apparatus for determining the location of a node within a communication system is provided herein. During operation, located nodes (105) having known locations are utilized to locate “blind” nodes (200) whose location is to be determined. More particularly, a blind node (200) wishing to determine its location will measure a plurality of signal strengths between itself and a plurality of located nodes (105). Each located node'"'"'s signal strength will then be adjusted based on at least one antenna gain pattern. A radio-location algorithm will then be executed on the adjusted signal-strength measurements to determine the nodes location.
