【Abstract】 In this paper,the mechanisms and the factors of landslide are introduced.In terms of analysis on the existing methods for landslide observation,a scheme of landslide monitoring based on wireless sensor network(WSN) is proposed.The WSN is composed of sensor nodes and gateway.The construction of sensor nodes and gateway are presented.Point to Point communication on RF modular,CC2520,for transmitting the sensing data of temperature and humidity is tested.The energy efficient routing protocol of the network is simulated through NS2.Both the results of simulation and experiment show that the presented WSN can meet the requirement of long-term observation and data transmission.WSNs has potential in landslide monitoring.更多还原
