Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
Frame format design side in a kind of self-organized network communication proposed according to embodiments of the present invention is described with reference to the accompanying drawings
Method and device.
Frame format design in a kind of self-organized network communication proposed according to embodiments of the present invention is described with reference to the accompanying drawings first
Method.
Fig. 1 is according to the frame format design method flow chart in a kind of self-organized network communication of one embodiment of the invention.
As shown in Figure 1, frame format design method in a kind of self-organized network communication the following steps are included:
In step s101, target time slot is determined in N number of time slot, sends data in target time slot；Wherein, N is positive whole
Number.
Further, in one embodiment of the invention, a frame is made of multiple subframes in self-organized network communication, and one
Subframe is made of multiple time slots.
The step in, select a time slot as target time slot in multiple time slots of a subframe, and in selection
Data are sent in target time slot.
In step s 102, Data duplication is sent M by the target time slot of each subframe in the corresponding frame of N number of time slot
Time；Wherein, M is the number of subframe and is positive integer.
Further, in one embodiment of the invention, data are repeatedly transmitted in time number and subframe
Number is identical.
Specifically, a frame is made of multiple subframes, repeats to send data in the target time slot of multiple subframes, repeats to send out
Send the number of data equal with the number of subframe.
In step s 103, after receiving data in any time slot of any subframe, in next height of any subframe
Frame repeats to send data to any time slot in the last one subframe of same frame.
Specifically, after having sent data in the target time slot of multiple subframes, then in multiple time slots of multiple subframes
Detection data, after detection receives the data of transmission in any time slot in any sub- frame, in this for detecting data
Next subframe of subframe repeats to send the data that detection receives to this time slot in the last one subframe of same frame.
As shown in Fig. 2, in this frame structure, frame is most basic chronomere, and a frame includes several subframes, one
A subframe includes several time slots.Time slot is the smallest chronomere, when multiple users communicate, each user occupancy when
Between resource be allocated according to time slot.
In self-organized network communication, due to non-stop layer node, in order to guarantee that information is reachable between any two node, information is needed
It to be forwarded between each node, hop count refers to the same message of some user, the number being repeatedly transmitted in time.
In Fig. 2, a frame is divided into 6 subframes, and 1 subframe is divided into 16 time slots.But in practical application, one
A frame is divided into arbitrary subframe, and a same subframe is divided into any time slot.
Below with the frame format design method in a kind of specific embodiment self-organized network communication that the present invention will be described in detail.
When some user needs to send data, need to select a time slot in 16 time slots, and arrive subframe in subframe 0
Corresponding time slot repeats to send in 5.When other users are not sent, the moment is in reception state.When some user receives data
Afterwards, next subframe after receiving the data is needed, into the last one subframe of same frame, in the correspondence for detecting data
Time slot, repetition send the data received by him.
Such as: user 1 sends data in time slot 0, he needs that Data duplication is sent 6 in the time slot 0 of subframe 0 to subframe 5
Time；If user 2 detects the data that user 1 sends in 0 time slot 0 of subframe, he needs to receive in the time slot 0 of subframe 1 to subframe 5
The Data duplication arrived is sent 5 times；If some user receives data in the time slot 0 of subframe 3, he needs in subframe 4 and subframe 5
Time slot 0 by the Data duplication received send 2 times.
Further, in one embodiment of the invention, further includes:
Obtain type of service；
N number of time slot is grouped according to type of service；Wherein, different groups supports that different data are weighed in time
Recur the number sent.
Above content describes a defeated example of 6 jump set under this frame structure, different in this frame structure
Type of service can support different hop counts, however it is not limited to the equal length of hop count and subframe.It can be by time slot by type of service point
Group, different groups support different hop counts.Such as certain 3 jump set of business support is defeated, needing to divide subframe 0 to subframe 2 is one group,
It is one group that subframe 3 is divided to subframe 5, and corresponding information is only sent in corresponding group.
The frame format design method in a kind of self-organized network communication proposed according to embodiments of the present invention, passes through specific mode
