Abstract

To address the defects of existing tracking method in some industrial applications, a new wireless sensor network tracking method is put forward based on ultrasonic and CSMA/CD mechanism: prior to each positioning, unknown node need to query the current ultrasonic channel state to determine whether the next step is to locate or to wait. After the completion of the positioning, the unknown node will broadcast positioning ended signal to release the channel. The results of MATLAB simulation of existing method and CSMA/CD alike method show that in a particular application, the new method can reduce the tracking error and extend the nodes’ lifespan.
