Abstract:
A positioning method for a sensor node is provided, and the method includes steps of: providing a first antenna having a first omnidirectional radiation pattern on a first plane; rotating the first antenna about an axis substantially parallel to the first plane; transmitting a wireless signal while the first antenna rotates about the axis for every a predetermined central angle; receiving the wireless signal at the sensor node; obtaining Received Signal Strength Indications (RSSIs) of the respective wireless signals; and determining a location of the sensor node according to the RSSIs.
