Experimental Analysis of RSSI-based Underground Tunnel Localization with Wireless Sensor Networks

摘要

Wireless Sensor Networks (WSNs) is a self-organizing network consisting of a large number of sensor nodes interacting with the physical world. Localization of sensor nodes is an essential issue in WSNs. RSSI-based localization can be implemented conveniently, in addition this technology is cost-efficient and power-efficient in practice. However, limited attention has been paid to underground tunnels environments. In this paper, we present an experimental study of RSSI-based localization in underground tunnels. The sensor nodes used are specially designed based on a 2.4GHz low power radio chipset CC2430 for ZigBee. Experimental results confirm the applicability of RSSI-based localization in underground tunnels.
