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.
