英文摘要：

The study aimed to find an effective energy-saving routing strategy for the application of wireless sensor networks to the monitoring of farmland micro climate and soil moisture. Aiming at the disadvantages of the layered tree routing algorithm and ZigBee routing algorithms in energy saving, an optimal node analysis model based on fuzzy decision was established according to ZigBee networks＇ topology characteristics, and then a new energy-saving rou- ting algorithm suitable for a large-scale, gradual changing farmland environment was put forward. This new algorithm finds out the quantitative relation between the energy consumption and the routing node selecting strategy, and greatly decreases the route hop number by the routing discovery mechanism and the creation of an optimum goal group. The simulation results show that compared with the layered tree and ZigBee routing algorithms, the new rou- ting algorithms can significantly reduce the energy consumption in the routing process.
