Problems solved by technology

However, their common problem is that the convergence time of the algorithm is too long, and even the algorithm cannot guarantee the convergence, so that the time actually used for data transmission is relatively reduced, and the actual bandwidth increase effect is not obvious, or even reduced.

Embodiment Construction

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0022] The inventor noticed during the invention that:

[0023] At present, a variety of link scheduling algorithms suitable for wireless ad hoc networks have been proposed. However, their common problem is that the convergence time of the algorithm is too long, and even the algorithm cannot guarantee the convergence, so that the time actually used for data transmission is relatively reduced, and the actual bandwidth increase effect is not obvious, or even reduced. In addition, some algorithms also assume that nodes have full-duplex wireless transceiver capabilities ...

Abstract

The invention discloses a high bandwidth data transmission method in a wireless ad hoc network. The high bandwidth data transmission method in the wireless ad hoc network comprises: in the process of data transmission in the wireless ad hoc network, a synchronous CSMA/CA(Carrier Sense Multiple Access with Collision Avoidance) protocol is adopted in an MAC sublayer, and in a LLC (Logical Link Control) sublayer, links are scheduled according to a distribution type MIS (Maximal Independent Set) algorithm of a diagram. The high bandwidth data transmission method enables the convergence time of the link scheduling algorithm in the process of data transmission in the wireless ad hoc network to be shorter, and compared with a conventional link layer which merely adopts the CSMA/CA protocol, the bandwidth performance is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a high-bandwidth data transmission method in a wireless ad hoc network. Background technique [0002] A large-scale wireless network is a cooperative network composed of distributed wireless nodes, and its application range is very wide. The most representative application is the video surveillance network. When the area to be monitored is large and wiring is difficult, each monitoring node is equipped with a 3G / GPRS (3GPP, 3rd Generation partnership project, 3rd Generation cooperation project / General PacketRadio Service, general Packet radio service) communication module solution, its manufacturing cost and operating cost are relatively high at present. A cheap solution is to use wireless ad-hoc network to transmit surveillance video to the server. This solution not only does not require 3G / GPRS communication modules, but also does not require any additional intermediate...
