Embodiment 1

[0139] In the multi-hop link data transmission method provided by Embodiment 1 of the present invention, its flow is as follows Figure 4 shown, including the following steps:

[0140] S101: The source site becomes the first site.

[0141] S102: Whether the first station completes the transmission of all data frames. If "Yes", go to S103; if "No", go to S104.

[0142] S103: the first site passes the first site qualification to the next-hop site, and the next-hop site becomes the first site.

[0143] The first site passes the first site qualification to its next-hop site through the flag bit on the last data frame or through a separate MAC frame, and its next-hop site becomes the first site, and the current first site exits the multi-hop link. data transmission. Transfer to S102 after the next hop site becomes the first site.

[0144] S104: When the first station has a data frame to send, obtain the transmission permission.

[0145] As the first site of a multi-hop link, ...

Embodiment 2

[0173] In the multi-hop link data transmission method provided by Embodiment 2 of the present invention, its flow is as follows Figure 5 shown, including the following steps:

[0174] S201: When the first station has a data frame to send, obtain the transmission permission.

[0175] As the first site of a multi-hop link, when it needs to send data, it will automatically obtain the transmission permission. Such as image 3 For the multi-hop link shown in , when the first site A needs to send data to the next hop relay site B, it automatically obtains the transmission permission.

[0176] Before this step, the first site qualification transfer process as described in steps S101-S103 may also be performed in advance.

Abstract

The invention discloses a data transmission method, system and device in a multi-hop link. The method includes the steps that stations in the multi-hop link acquire transmission permission according to set permission transmitting rules; when each station determines that the next binary-hop station has completed data transmission, the station transmits data frames to be sent to the next hop station. Data transmission is controlled through transmission permission transmitting, so that the problem of being low in data transmission efficiency caused by channel competition among the stations is avoided, and overall performance of a network is promoted.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a data transmission method, system and device applicable to a multi-hop link of a wireless ad hoc network. Background technique [0002] Since the worldwide information technology revolution occurred in the last century, wireless communication technology has been greatly developed and applied, such as: cellular network and wireless local area network have been popularized as ordinary civilian technologies and widely used. However, most of the currently used wireless networks are managed by the central base station. The cellular network is a typical wireless network that communicates through the central base station. Although the wireless local area network standard does not stipulate that it must have a central base station, in practice In the application, the wireless local area network generally has a central base station. The disadvantages of the wireless ne...
