Method of sensor network localization through reconstruction of radiation pattern
First Claim
1. A method of localization through reconstruction of a radiation pattern, the method comprising:
- providing a sensor network that includes a plurality of sensor nodes and a gateway, wherein each of the sensor nodes and the gateway includes an antenna for communicating with each other;
measuring a radiation characteristic value of each of the antennae which depends on transmission and reception sensitivity of a selected antenna varying with the orientation of the selected antenna in the sensor network;
measuring radiation patterns of a first sensor node and a second sensor node of the plurality of sensor nodes; and
measuring a position of a third sensor node based on the radiation characteristic value of an antenna corresponding to the third sensor node and the radiation patterns of the first and second sensor nodes.

Abstract
Disclosed herein is a method of sensor network localization through reconstruction of a radiation pattern with a characteristic value of an antenna depending on orientation thereof. The method can minimize errors using an antenna characteristic value and a signal strength depending on the orientation. In addition, the method can minimize errors using an artificial neural network to characterize a distorted radiation pattern of an antenna and using it for the localization of a triangulation method. Furthermore, the method can increases the localization rate even in a passive localization method by characterizing an asymmetric antenna radiation pattern and constructing the antenna characteristic through an artificial neural network.
