Embodiment 1

[0030] Embodiment 1 Wireless ad hoc network communication method

[0031] This embodiment provides a time division-based wireless ad hoc network communication method, see Figures 1 to 4 and 8 to 10, the time division-based wireless ad hoc network communication method includes:

[0032] Step S102, dividing the predetermined time period into N time slices, including signaling frame time slices and data frame time slices, wherein N is an integer greater than 2;

[0033] Specifically, as Figure 8 As shown, the predetermined time period 300 is divided into N time slices. In the preferred embodiment provided by the present invention, the predetermined time period 300 is 125 μs, and N is equal to 32. In the embodiment provided by the present invention, the length of the predetermined time period 300 and the value of N can be selected according to actual design requirements. It is not good if the predetermined time period is too long or too short. If the time period is too long,...

Embodiment 2

[0047] Embodiment 2 Wireless ad hoc network communication device

[0048] This embodiment provides a wireless ad hoc network communication device based on time division, such as Figure 5-10 As shown, the wireless ad hoc network communication device based on time division may include: a time division module 10 , a signaling frame sending module 12 and a data frame sending module 14 .

[0049] The time division module 10 is configured to divide a predetermined time period into N time slices, including a signaling frame time slice and a data frame time slice, where N is an integer greater than 2. Specifically, the division method of the time period 300 is as follows Figure 8 As shown, it has been described in detail in the first embodiment, and will not be repeated here.

[0050] The signaling frame sending module 12 is used for determining the network coordinator and sending signaling frames in the signaling frame time slice to perform signaling maintenance operations. The s...

Abstract

The invention discloses a wireless ad hoc network communication method and device based on time division. The time-division-based wireless ad hoc network communication method includes: dividing a predetermined time period into N time slices, including signaling frame time slices and data frame time slices, wherein N is an integer greater than 2; determining a network coordinator and Send signaling frames in signaling frame time slices to perform signaling maintenance operations, the signaling maintenance operations include network maintenance, clock synchronization, node access and transmission path addressing; and send data frames in data frame time slices to perform Data communication; wherein, the time slice of the signaling frame includes the first time slice. The invention adopts the time-division principle to time-divisionally isolate the network routing maintenance channel from the data transmission channel, so that the bandwidth occupied by signaling maintenance can be controlled according to the network change status. Solved the problem of low actual network transmission rate caused by route consumption.

Description

technical field [0001] The present invention relates to the technical field of ad hoc networks, in particular to a time division-based wireless ad hoc network communication method and device. Background technique [0002] An ad hoc network is a network that combines mobile communications and computer networks. There is no central entity in the wireless ad hoc network. Each node in the ad hoc network has both router and host functions. Nodes do not need to be managed and controlled by base stations or other central equipment, and can directly communicate point-to-point. If the two nodes cannot realize the link connection due to the coverage of the signal, other nodes in the network can help to transfer, and realize the mutual communication between the nodes in the network in the form of multi-hop. Wireless ad hoc network nodes can enter and leave the network dynamically, randomly and frequently without causing the entire network to fall into paralysis. Due to the characteri...
