1. A sensor node device included in a sensor node system for mapping hydraulic fractures, the sensor node device comprising:
a localization system that identifies location information of the sensor node device with respect to an area of interest in a rock formation, the location information including a plurality of magnetization parameters indicative of a plurality of signal strengths surrounding the sensor node device;
a transceiver that exchanges signals with a base station and at least one other sensor node device, the transceiver establishing a communication link between the base station and the sensor node device and monitoring at least one other communication link between the at least one other sensor node device and the base station;
a processor that identifies distance information based on the location information and a predetermined number of signals associated to the plurality of signal strengths surrounding the sensor node device; and
a coordination system that maps a real time position of the sensor node device in the rock formation based on the distance information identified.
