| 1T2R | NACK | ACK | NACK |
| 2T2R | |||
| 3T2R | ACK | ||
| 4T2R |
Calculated from formula N=INT (Q/A+1), present count value N is 3, i.e., each sending node is sent out to receiving node
The number maximum of breath of delivering letters is 3.
As shown in table 2, node 2 receive node 1 transmission information reach three at first, node 2 also have received node 3 and send out
The information sent, then the broadcasting reception state feedback information when its next fixed sending time slots arrives of node 2.It is worth pointing out
As long as the information number for having a node to be sent to node 2 reaches 3, node 2 will be to information number that it is received
Again counted, its reception state feedback information broadcasted includes its all information sent to receiving each node
The feedback information of reception state.
Specifically, referring to table 1 (sequence number of the numeral expression multi-frame of first row in table 1), in the first multi-frame, node 1 exists
When its two time slot fixed in time slot 1 and dynamic slot arrives, three information are have sent to node 2, i.e., first is multiple in table 1
1T2R (1), 1T2R (2) and 1T2R (3) in frame；Node 3 have sent a letter when it is fixed time slot 3 and arrived to node 2
Breath, i.e. 3T2R.In addition, in the first multi-frame, there is the information exchange between other nodes.
Node 2 is when its next fixed sending time slots arrives, i.e., when the fixation time slot 2 of the second multi-frame arrives, in nothing
Broadcasting reception state feedback information in line MANET, refer to table 3, i.e., the first information and the 3rd that the node 1 that node 2 receives is sent
The reception state of individual information is NACK, and the reception state of second information and the node 3 of reception of the transmission of node 1 of reception are sent out
The reception state for the information sent is ACK.
If node 1 receives the reception state feedback information of the broadcast of node 2, first information and the 3rd information are known
Reception state be NACK, then first information and the 3rd information are resend when next sending time slots arrive, can be with
Time slot 1 is fixed at it to be resend, can also be resend in dynamic slot, and example is in dynamic in table 1
Resend in time slot, i.e. the 1T2R (1) and 1T2R (3) sent in the first multi-frame dynamic slot；Know connecing for second information
Receipts state is ACK, then abandons second information, send fresh information when next sending time slots arrive, can be fixed at it
Time slot 1 is transmitted, and can also be transmitted in dynamic slot, and example is to fix time slot 1 at it to send new letter in table 1
Breath, the i.e. 1T2R (new) that the 3rd multi-frame is fixed in time slot 1.
If node 3 receives the reception state feedback information of the broadcast of node 2, know that it is sent to the information of node 2
Reception state is ACK, then abandons the information, and fresh information is sent when next sending time slots arrive, can be when it is fixed
Gap 3 is transmitted, and can also be transmitted in dynamic slot.
According to the formula M of given threshold>T, T=INT [(A-1) × (N-1) × A/Q], which are calculated, to be understood, T=3, then M can be with
It is taken as 4.
If node 1 determines to be not received by the reception state feedback information of the broadcast transmission of node 2 in 4 multi-frames,
Assert that the reception state feedback information that node 2 is sent is lost, therefore, node 1 can be sent not to node 2 again after 4 multi-frames
Three information of the feedback information of reception state are received, i.e., in table 1 in the 5th multi-frame in fixed time slot 1 and dynamic slot
1T2R (1), 1T2R (2) and the 1T2R (3) resend.
