SYSTEM AND METHOD FOR TRACKING A MOBILE NODE
First Claim
1. A method of tracking a mobile node in a field of nodes, comprising:
- receiving, at a selected node, positional data indicating a geographic location of the mobile node within the field of nodes, the positional data including location measurements conducted by other nodes in the field of nodes;
collecting historical positional data of the mobile node, the historical positional data including a plurality of geographical locations of the mobile node within the field of nodes over a period of time;
tracking a geographic path and movement characteristics of the mobile node in the field of nodes within the period of time based on the historical positional data;
predicting future geographic locations of the mobile node within a period of future time based on the geographic path and the movement characteristics of the mobile node; and
estimating a time of arrival and a likelihood of arrival of the mobile node to a defined proximity of the selected node, by factoring the future geographic locations of the mobile node within the period of future time.

Abstract
Techniques for tracking the position and movement of a mobile node within a field of fixed nodes are disclosed herein. In one embodiment, positional information generated from neighboring nodes in the field of nodes along with positional information obtained from the mobile node itself is compiled and used to track the location of the mobile node. The field of fixed nodes may relay positional information to interested nodes within the field in order to communicate the movement of the mobile node. Based on the positional information of the mobile node, the mobile node can be tracked, and an estimated time of arrival and a likelihood of reaching a defined point or a fixed node can be computed. Additionally, fixed nodes may use the estimated time of arrival and likelihood calculations to initiate anticipatory processing if the mobile node is likely to encounter the fixed node.
