1. A wireless node location system, the system comprising:
- a) a system data store capable of storing configuration information;
b) a system processor comprising one or more processing elements, wherein the system processor is in communication with the system data store and wherein the system processor is programmed or adapted to perform the steps comprising of;
i) receiving an address associated with a wireless node;
ii) transmitting a query comprising the address to each device in a wireless network capable of receiving signals from the wireless node;
iii) receiving one or more responses to the transmitted queries;
iv) calculating a position of the wireless node associated with the address based upon the received one or more responses; and
v) outputting the calculated position.

Abstract
A node identification and location system includes a system data store and a system processor. The system processor performs the node location function through appropriate methods such as described herein. In one such method, an address associated with a wireless node is received. A query is transmitted to each device in a wireless network capable of receiving signals from the wireless node. Responses are received from one or more responding devices. The position of the wireless node is calculated based upon the received one or more responses. The calculated position is outputted.

18. A method for locating a wireless node, the method comprising the steps of:
-
a) receiving configuration information comprising network configuration and default data from a configuration file, an interactive data entry interface or a command line interface or from monitoring a wireless computer network;
b) receiving an address associated with a wireless node used by a potential intruder from an intrusion detection system;
c) transmitting a query comprising the address to each device in a wireless network capable of receiving signals from the wireless node;
d) receiving one or more responses to the transmitted queries, wherein each of the received responses comprises a signal strength value of the wireless node relative to the responding device;
e) calculating a position of the wireless node associated with the address based upon the received one or more responses by;
i) computing signal strength distance to each responding device by calculating the square root of the sum of squares of three responding device signal strength values;
ii) identifying a set of the responding devices having a computed signal strength distance less that a determined value;
iii) estimating the position of the wireless node as within the identified set; and
iv) refining the position of the wireless node by determining the position of the wireless node to be within proximity of the responding device in the identified set with the strongest signal strength value;
f) updating a position data store with the calculated position of the wireless node and its address; and
g) outputting the calculated position to the intrusion detection system.
