摘要：Plant sap flow detection plays an important role in water consumption research and plant growth rule. Wireless Sensor Networks (WSN) can effectively realize that transmit the data back to PC. How to prolong the service life of wireless sensor network with the limited energy is a key point. To solve the problem, a novel energy-efficient division- frame MAC (DF-MAC) protocol applied for Wireless Sensor network to detect plant sap flow is proposed in this paper. The idle listening time is shorten in DF-MAC, and wireless equipment is operated in low power of sleep mode to save energy when data transmission is not occurred. DF-MAC has two major characteristics: low number of collisions and low duty cycle. The nodes of sensor in DF-MAC have shorter listening time that would save the power of communicating with other nodes. The number of collisions is minimized in DF-MAC which can save the energy required to send data packages again. According to the consequences of simulation, the energy depletion of DF-MAC Protocol is much lower compared with the existing MAC. DF-MAC is of theoretical and applied significant for plants sap flow measurement in practice.
