Abstract
A control method for a heterogeneous wireless sensor network (WSN) bridging device includes initializing Zigbee sensor nodes, switching a Zigbee transceiver module to a sleep mode, switching a wireless network transceiver module to an active mode, receiving an task list from a remote main control device, switching the wireless network transceiver module to the sleep mode, switching the Zigbee transceiver module to the active mode, transmitting an operating instruction to the Zigbee sensor nodes, receiving at least one sensing signal from the Zigbee sensor nodes, and determining whether the sensing signals have been received. If yes, a back transmission procedure is executed. The control method solves an interference problem among heterogeneous wireless networks and overcomes a bottleneck in data transmission.
