This paper proposes an energy-efficient route finding scheme based on the directional antenna in Wireless Sensor Network(WSN).This paper derives the relationship between the number of hops and the energy consumption within a certain source-destination distance by analyzing the major factor influencing the power consumption on wireless channels.Combined with the benefits from directional antennas,it proposes an energy-efficient routing scheme which selects the next hop according to the optimal route and geographic coordinates of sink and sensors.Simulation result shows the significant improvement by reducing the flooding cost,selecting an energy-efficient route and saving energy.
