Patent ID: 7589672

Claim:
A method for determining positional data of a mobile node of a network that includes a plurality of mobile nodes, comprising: providing a first and second coordinate system wherein the first coordinate system is a relative coordinate system to the second coordinate system; relating the positional data of the mobile node to the first coordinate system; determining a subset of nodes form a plurality of nodes located within the first or second coordinate system, wherein at least a portion of the subset of nodes are mobile; selecting an outlier mobile node that is not part of the subset of nodes; and identifying a position of the outlier mobile node via the steps: providing positional data for the subset of nodes, wherein the positional data describes the respective position of the subset of nodes in the first coordinate system, determining distances of the outlier node to the subset of nodes, and determining the positional data of the outlier node based upon the positional data of the subset of nodes, and the determined distances of the outlier nodes and the positional data of the outlier node.
