摘要： Illegal logging is a pervasive problem due to lack of effective monitoring methods. A novel wireless method for illegal logging is proposed which leverage the RSSI ranging and communication of WSN and GPRS. The node displacement incurred by tree's falling down can be detected in time. Furthermore, failure of target node can be judged with its neighbor cooperation. The effectiveness and efficiency of this system was verified in our test-bed. Thus this solution has several characteristics such as lower power, remote, lower cost, real-time and non-intrusive, which are very appropriate to protect rare trees continuously.
