Abstract

The invention provides a multi-channel and multi-rate concurrent communication method based on a wireless frequency hopping network, relates to the technical field of network communication, and solves the technical problem that the efficiency of a transceiver is reduced due to multiple times of channel switching during data frame transmission. The method comprises the following steps: dividing a communication bandwidth into n frequency bands, and arranging the n frequency bands in an ascending order; dividing the channels into n channels, and numbering the n channels in sequence; enabling the n frequency bands and the channels to be in one-to-one correspondence to form a channel frequency band table; allocating time slots to the channels according to a time sequence to form a frequency hopping graph; allocating a frequency hopping time limit and a channel to the current communication data according to the communication rate of the current communication data; and transmitting the current communication data by the transceiver. According to the invention, a plurality of time slots and a plurality of channels are occupied through one-time communication, and a reasonable frequency hopping interval is designed, so that the time slots of the system can be used in association with all central frequency point communication channels in a balanced manner, frequency resources are saved, and the problem of low efficiency of a traditional frequency hopping method is thoroughly solved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a multi-channel multi-rate concurrent communication method based on a wireless frequency hopping network. Background technique [0002] The traditional wireless frequency hopping network technology is that the communication devices in the network switch the frequency of the communication channel according to the predetermined time interval and frequency hopping pattern. According to the requirements, every ΔT time period (that is, a time slot) of the device receiver in the network will jump to a new communication frequency for reception. If there is a device that needs to send data, it will also start on this frequency within this time period The transmitter sends data. At the end of this time period, all devices immediately switch to the next frequency. According to this mechanism, if the transmitter does not send all the data in a time slot, it needs to stop sen...
