1. A sensor network for determining a local arrangement of several sensor nodes, wherein the sensor network comprises:
- a plurality of sensor nodes, wherein each sensor node comprises;
a sensor unit configured to acquire signal parameters from adjacent sensor nodes of the plurality of sensor nodes, based upon which signal parameters a position of the sensor node within the sensor network is determinable; and
a communication unit configured to communicate with other sensor nodes of the plurality of sensor nodes and to transmit data based on the acquired signal parameters to a central processing unit,wherein the central processing unit is configured to receive the data transmitted by each of the plurality of sensor nodes and to determine relative positioning of each sensor node of the plurality of sensor nodes with respect to the other sensor nodes of the plurality of sensor nodes by correlating the transmitted data, andwherein the relative position of each of the plurality of sensor nodes is determined based on a correlation of data received from the several sensor nodes of the plurality of sensor nodes.

Abstract
The invention relates to a sensor network for determining the position of devices and gear in an aircraft. The sensor network exhibits several sensor nodes, which have an autonomous power supply. The sensor nodes can communicate wirelessly with each other and with a central processing unit. The position of each individual sensor node can be determined by evaluating high-frequency signal parameters.
