Embodiment 1

[0030] Embodiment 1 Wireless Ad Hoc Network Communication Method

[0031] This embodiment provides a wireless ad hoc network communication method based on time division, see Figure 1~4 And 8~10, this wireless ad hoc network communication method based on time division comprises:

[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, such 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 may 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...

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, and N is an integer larger than 2; a network coordinator is determined and a signaling frame is sent 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 a data frame is sent 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 ad hoc network technology, in particular to a time division-based wireless ad hoc network communication method and device. Background technique [0002] Ad hoc network is a combination of mobile communication and computer network. There is no central entity in the wireless ad hoc network. Each node in the ad hoc network has both functions of a router and a host. The nodes do not need to be managed and controlled by a base station or other central equipment, and can directly perform point-to-point communication. If two nodes cannot achieve link connection due to signal coverage, other nodes in the network can help to transfer and realize mutual communication between nodes in the network in the form of multi-hop. Wireless ad hoc network nodes can enter and leave the network dynamically, freely and frequently without causing the entire network to be paralyzed. Due to the characteristics of random node mobili...
