Abstract :
In this paper two key factors of distributed sensor network for soil moisture monitoring are studied. One factor is the sensor design based on global navigation satellite system reflection (GNSS-R) signal, the other is the sensor placement. At first this paper introduces the construction and the advantage of non-contact soil moisture sensor, then the paper gives the optimization method based on greedy algorithm for sensor placement to conserving energy. Simulation results for multiple nodes placement confirm the validity of the proposed method.
