Long-range wireless sensor networks for geo-location tracking: Design and evaluation

Nowadays, a long-range data transmission is required in numerous Internet of Things (IoT) applications. This paper introduces a long-range Wireless Sensor Networks (WSN) for geo-location tracking of mobile objects as one of the applications. In the proposed system, the geo-location information of moving objects is collected and sent over wireless networks with a reconfigured GPS and LoRa (Long Range) modules. This work presents the design of long-range WSN system and the prototype implementation. We implement multiple sensor nodes deployment, which move away from a static base station called dock. Further, the reliability of geo-location data collection and the quality of wireless communication are evaluated. The results from RSSI test show a high reliability of LoRa module as a transceiver for our targeted long-range geo-location tracking application.
