Embodiment 1

[0030]Example a wireless self-network communication method

[0031]This embodiment provides a method of time-based wireless self-network communication method, seeFigure 1 ~ 4 withFigure 8 - Figure 10 The time-based wireless self-network communication method includes:

[0032]In step S102, the predetermined time period is divided into N time slice, including the signaling frame time sheet and the data frame time slice, wherein the N is an integer of greater than 2;

[0033]Specifically, such asFigure 8 As shown, the predetermined time period T is divided into N time slice. In a preferred embodiment of the invention, a predetermined time period T is 125 μs, n is equal to 32. In the embodiment provided by the present invention, the length and N of the predetermined time period T can be selected according to the actual design needs. The predetermined time period is too long or too short, the time period is too long, which will result in determining the waiting time of the network coordinator and...

Embodiment 2

[0048]Example two wireless self-network communication device

[0049]This embodiment provides a wireless self-network communication device based on time division, such asFigure 5 - Figure 10As shown, the time-based wireless self-network communication device can include: a time division module 10, a signaling frame transmitting module 12, and a data frame transmitting module 14.

[0050]The time division module 10 is configured to divide the predetermined time period into N time slice, including signaling frame time sheets and data frame time slips, wherein the N is an integer greater than 2. Specifically, the segmentation method of time period T is likeFigure 8 As shown in the first embodiment, it has been described in detail in this example.

[0051]The signaling frame transmitting module 12 is configured to determine the network coordinator and send a signaling frame in the signaling frame time to perform signaling maintenance operations, including network maintenance, clock synchronizatio...

Abstract

The invention discloses a wireless ad hoc network communication method and device based on time division. The wireless ad hoc network communication method based on time division comprises the steps that a preset time period is divided into N time slices including a signaling frame time slice and a data frame time slice, wherein N is an integer greater than 2; determining a network coordinator and sending a signaling frame in a signaling frame time slice so as to carry out signaling maintenance operation, wherein the signaling maintenance operation comprises network maintenance, clock synchronization, node access and transmission path addressing; and sending a data frame in the data frame time slice to perform data communication, wherein the signaling frame time slice comprises a first time slice. According to the invention, a time division principle is adopted, time division isolation is carried out on a network routing maintenance channel and a data transmission channel, and the bandwidth occupied by signaling maintenance can be controlled according to the network change condition. The problem of low actual network transmission rate caused by routing consumption is solved.

Description

Technical field[0001]The present invention relates to the field of wireless communication technologies, and more particularly to a time-based wireless self-network communication method and apparatus.Background technique[0002]The self-networking network is a network that combines mobile communication and computer networks. There is no central entity in the wireless self-network network. Each node in the self-network network has two functions of routers and hosts. The node does not need to be used through the base station or other central device management and control, and can directly perform a point-to-point communication. If the two nodes cannot implement a link connection due to the signal coverage, the other nodes in the network can help to transfer, and implement mutual communication between the networks in the network in the form of multi-hop. Wireless self-network nodes are dynamically, freely, frequently, frequently entering and leaving the network, and will not cause the ent...
