Abstract

The invention discloses a broadcasting method and a broadcasting device for a wireless ad hoc network, belonging to the technical field of wireless communication. The broadcasting method includes: the first wireless node obtains the whole network routing information of the wireless ad hoc network, selects the gradient central point; obtains the gradient value of the whole network; determines the sending time slot according to the gradient value of the whole network, when the first wireless node is the gradient central point , the sending time slot includes a diffusion time slot, and in the diffusion time slot, the gradient central point sends a broadcast message cluster; when the first wireless node is a wireless node other than the gradient central point, the transmission time slot includes a convergence time slot and a diffusion time slot , in the convergence time slot, the first wireless node sends a broadcast message to the second wireless node; in the diffusion time slot, the first wireless node sends a broadcast message cluster to the third wireless node. Then each wireless node can determine its own sending time slot without sending a request to the central node and waiting for the central node to allocate time slots for multiple wireless nodes, which improves the real-time performance of broadcast transmission.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a broadcasting method and a broadcasting device for a wireless ad hoc network. Background technique [0002] In some specific wireless ad hoc network application scenarios, most of the data transmission messages are low-speed and short, but these messages have high requirements for connectivity and real-time performance, such as voice transmission services in complex terrain . In order to meet the high availability of such low-speed small packets, it is necessary to design a broadcast transmission mechanism with high reliability and low delay. [0003] The existing network topology is usually collective, that is, the network includes a central node, and the corresponding broadcast method is: when a certain wireless node needs to send a broadcast frame, the wireless node sends a request to the central node, and then The wireless node is allocated time slot...
