System, medium, and method for estimating distance in communication system having nodes
First Claim
1. A method for estimating an unknown location of a first node in a communication system including nodes having known locations and nodes having unknown locations, comprising:
- transmitting and receiving first packets between nodes having known locations via the first node;
sending a second packet to the first node, the second packet containing a distance function coefficient acquired using first information and second information included in at least one of the first packets; and
estimating the unknown location of the first node using the distance function coefficient.

Abstract
A method, medium, and system estimating a location of a node, whose location is unknown, in a communication system including both nodes having known locations and nodes having unknown locations. A first packet is transmitted and received between nodes having known locations, via a node having an unknown location to be estimated. A second packet, which contains a distance function coefficient acquired using first information and second information included in the received first packet, is transferred to the node having the unknown location to be estimated. The unknown location is then estimated using the received distance function coefficient.

12. A system estimating an unknown location of a second node using a known location of a first node, both in a communication system, comprising:
-
the first node generating a second packet containing a distance function coefficient calculated using first information and second information contained in a first packet received via the second node; and
the second node estimating its location using the distance function coefficient, as received by the second node in the second packet. - View Dependent Claims (13, 14, 15, 16, 17, 18, 20)
