Wireless ad hoc network based electronic price biding system and communication method

The invention relates to a wireless ad hoc network based electronic price biding system and a communication method. The wireless ad hoc network based electronic price biding system comprises a plurality of label nodes, a plurality of routing nodes which are in wireless communication with the label nodes, Sink nodes which are in wireless communication with the routing nodes, a label management platform which sends the commodity information to the label nodes, a commodity database and a POS (Point Of Sale) cashing system; the Sink nodes, the routing nodes and the label nodes form into a label wireless network and communicate through a wireless transceiver of an ISM (Industrial Scientific Medical) frequency band and an ad hoc network process confirms to a network administration rule of the wireless ad hoc network based electronic price biding system; the Sink nodes and the label management platform are mutually connected in a wired mode. According to the wireless ad hoc network based electronic price biding system, the electronic price biding system is established through the wireless ad hoc network, the commodity information is updated in real time, the label network is unitedly monitored and managed, and a large-scale wiring can be avoided and route ad hoc network and label low-power-consumption applications can be achieved due to the fact that the label network is in a wireless ad hoc network communication mode.
