A RSSI-Based Location System in Coal Mine
To meet the need of safe production in coal mine,aRSSIobased location system of wireless sensor networks isdesigned.According to signal decay model of 2.4GHzmicrowave and the data measured at site,we obtain the RSSIrange model of 2.4GHz microwave.Consideration of thetopographic features and practical needs of coal mine,thelocation algorithm that is suitable for coal mine is designed.The simulation results and practical test show that theRSSI-based location system we designed is easy to implementand has a higher accuracy.
