Referring to fig. 7, the ad hoc network communication method according to the embodiment of the present invention includes steps 1 to 3.
Step 1: connecting the ad hoc network, searching the corresponding ad hoc network equipment under the ad hoc network according to a preset protocol to obtain the physical address of each networking equipment, and dividing each networking equipment into a plurality of groups with communication sequence according to the physical address of each networking equipment and a preset grading rule. When the ad hoc network device accesses the ad hoc network, other ad hoc network devices under the ad hoc network are searched and corresponding physical addresses (MAC addresses) are obtained, and the ad hoc network device and other ad hoc network devices are uniformly divided into a plurality of groups according to a preset classification rule (for example, the order of the numbers and letters of the physical addresses can be determined, and the priority of users of the ad hoc network device can also be determined).
Step 2: and dividing a preset communication time interval into time periods corresponding to the ad hoc network devices according to the number of the groups and the number of the ad hoc network devices corresponding to each group, and starting to circularly time according to the communication time interval. For example, the next ad hoc network is connected with 7 ad hoc network devices, the ad hoc network is divided into two groups, i.e. group a and group b, according to the priority, the group a takes precedence over the group b, the group a has 2 ad hoc network devices, and the group has 5 ad hoc network devices, then the communication time interval 0.07 seconds (taking 0.07 seconds as an example) can be divided into 7 time slots, the group a has 2 ad hoc network devices respectively send messages in the first two time slots in the communication time interval, and the group 5 ad hoc network devices respectively send messages in the last five time slots in the communication time interval; the ad hoc network equipment starts grouping after accessing the ad hoc network, and starts to circularly time by 0.07 second communication time interval after the grouping is finished; and under the ad hoc network, each newly connected ad hoc network device is regrouped and time-counted again.
And 3, step 3: receiving a message sent by a user, and delaying the message to the corresponding time period of the current communication time interval for sending through electromagnetic waves when the time for receiving the message is before the corresponding time period of the current communication time interval; when the time for receiving the message is after the corresponding time period of the current communication time interval, the message is delayed to the corresponding time period of the next communication time interval and is sent through electromagnetic waves; and when the time for receiving the message is within the corresponding time period of the current communication time interval, immediately sending the message through electromagnetic waves. For example, when the time period allocated by the first ad hoc network device in the second group is within the third 0.01 second within 0.07 second of the communication time interval, and when the user of the first ad hoc network device in the second group sends a message within the first and second 0.01 seconds of a certain communication time interval, the message is delayed to the third 0.01 second of the current communication time interval for sending; when the user of the first Ad hoc network equipment in the second group sends a message in the fourth to seventh 0.01 seconds of a certain communication time interval, the message is delayed to the third 0.01 second of the next communication time interval for sending; when the user of the first ad hoc network device in the second group sends a message in the third 0.01 second of a certain communication time interval, the message is sent immediately. The ad hoc network communication method of the embodiment of the invention carries out grouping after the ad hoc network equipment is accessed into the ad hoc network, and simultaneously allocates a corresponding time period for each networking equipment connected with the ad hoc network, so that the ad hoc network equipment only sends messages in the corresponding time period, the technical effect of sending messages at intervals by each networking equipment is achieved, and the problem of mutual interference generated when a plurality of ad hoc network equipment send messages at the same time in the same ad hoc network is effectively solved.
