A wireless subway collision avoidance system based on ZigBee network is proposed in this paper. In the paper, all the ZigBee nodes are divided into two types, fixed nodes and mobile nodes. The fixed nodes are deployed in tree topology networks overlapped with each other along the subway tunnel; the mobile nodes are installed on the trains. The core idea is as soon as a fixed node establishing an association with a mobile node, the fixed node broadcasts the event with MAC address of the mobile node immediately.
