Embodiment Construction

[0035]In order to solve the problem that system resources cannot be fully utilized when selecting the route of transmitting data in the same direction of two nodes in the existing wireless transmission, the present invention determines the service type at the source node in the same direction between the source node and the destination node After that, obtain the corresponding transmission parameters according to the service type and select the route according to the parameters. In order to ensure the quality of service (QoS), a preferred way is to route the transmission parameters and current network state information.

[0036] Hereinafter, the present invention will be described in detail by taking the route selection determined according to the service type and the current network state information as an example.

[0037] As shown in Figure 3, the data transmission device as a node in the network includes (the data transmission device of the destination node is the same as ...

Abstract

This invention discloses one data transmission method. It is to solve the problem that current technology can't choose route to transmit data according to differences in type of business and then is unable to take full advantage of network resources and the effects quality of the business; this method uses source node to identify business type and obtain the corresponding transmission parameter, and sends the route choice request, then it at least chooses the route from source node to destination node according to the stated transmission parameter, and it creates the corresponding transmission link between source node and destination node according to route , then it transmits data through the transmission link. This invention also discloses a data transmission device.

Description

technical field [0001] The invention relates to data transmission technology in the field of wireless communication, in particular to a data transmission method and device. Background technique [0002] In the wireless communication system, according to the communication path between the source and the sink, it can be divided into two structures: one is the network structure where the source and the sink can communicate directly, such as a cellular structure; under the other structure, according to the situation , the communication between the source and the destination may require message forwarding through an intermediate node (hereinafter referred to as the second type of network as the forwarding network). As shown in FIG. 1 , two connected nodes indicate that a connection can be established between the two nodes through a wireless link. Apparently, a forwarding network typically presents a mesh structure. The multi-hop network and Ad hoc network studied in the field of...
