Abstract
A method and apparatus for determining a best technique (algorithm and/or parameters) to use when locating a node (104) is provided herein. In particular, reference nodes (105) are provided that not only know their own locations, but also test various algorithms and parameters by estimating their locations as if they were blind nodes. The reference nodes then evaluates these various techniques against the user defined criteria for the best technique. Recommendations as to the best technique to utilize are then made to other nodes within the system.

A method for determining a best location technique to use when locating a node, the method comprising the steps of:
- receiving location data from a plurality of nodes;
- calculating a plurality of location estimates using a plurality of location techniques, wherein the location estimates are based on the location data received from the plurality of nodes;
- determining the best location technique based on the plurality of location estimates;
- and
- providing information regarding the best location technique to other nodes to utilize when performing location.
