| Abstract: |
| Wireless sensor networks(WSNs) are promised for a wide range of military and civil applications.It is necessary for the nodes in a WSN to know their own physical locations.The node positioning algorithm is analyzed,and the system is set up to realize the precise localization for short distance by using the time difference of ultrasonic and radio.It possesses such advantages as simple structure,easy realization. |
