Abstract
A method of room based position determination for a mobile node in a positioning system is disclosed. The method comprises determining a room in an area deployed with at least a reference node of the positioning system, collecting a plurality of RSSI data from the at least a reference node in every place of the room, establishing a room fingerprint, performing a real-time RSSI measurement on the at least a reference node, to collect a plurality of real-time RSSI data from the at least a reference node, and determining whether the mobile node is within the room according to the RSSI mean parameter, the maximum distance parameter of the room fingerprint database and the collected real-time RSSI data from the at least a reference node.

A method of room based position determination for a mobile node in a positioning system, the method comprising:
- determining a room in an area deployed with at least a reference node of the positioning system;
- collecting a plurality of received signal strength indicator (RSSI) data from the at least a reference node in every place of the room;
- establishing a room fingerprint database, which includes a RSSI mean parameter indicating a RSSI value at the center of the room and a maximum distance parameter indicating a radius of the room, wherein the RSSI value and the radius are calculated according to the collected RSSI data from the at least a reference node;
- performing a real-time RSSI measurement on the at least a reference node, to collect a plurality of real-time RSSI data from the at least a reference node;
- and
- determining whether the mobile node is within the room according to the RSSI mean parameter, the maximum distance parameter of the room fingerprint database and the collected real-time RSSI data from the at least a reference node.
A method of room based position determination for a first reference node in a positioning system, the method comprising:
- determining a room in an area deployed with a mobile node of the positioning system;
- collecting a plurality of received signal strength indicator (RSSI) data from the mobile node moving within the room;
- establishing a room fingerprint database, which includes a RSSI mean parameter indicating a RSSI value at the center of the room and a maximum distance parameter indicating a radius of the room, wherein the RSSI value and the radius are calculated according to the collected RSSI data from the mobile node;
- performing a real-time RSSI measurement on the mobile node, to collect a plurality of real-time RSSI data from the mobile node;
- and
- determining whether the mobile node is within the room according to the RSSI mean parameter, the maximum distance parameter of the room fingerprint database and the collected real-time RSSI data.
