AbstractThe present invention relates to the industrial wireless network technology, and particularly to an OFDM technology-based frequency domain polling method for a wireless sensor network. The present invention comprises the steps of: initial polling configuration: an AP allocating a polling group ID and a subcarrier ID to a node which is newly added into a network OFDM frequency domain polling: the AP sending a polling request message, and after the node receives the polling request message, the AP responding in a frequency domain using an OFDM subcarrier and TDMA slot allocation and node data transmission: according to the response condition of each polled node, the AP allocating a TDMA slot to a node which needs data transmission and after the node receives the TDMA slot allocation result, conducting the data transmission in a corresponding slot. The present invention is proposed on the premise of fully taking into account the application characteristics of an industrial wireless network, and can reduce the network protocol overhead, and improve the bandwidth utilization rate and effective network throughput, thereby improving network timeliness and scale.
