Problems solved by technology

For the Ad Hoc radio network, it is difficult to establish multiple real-time forwarding links because its bandwidth is shared by multiple nodes and the topology structure will change constantly
At the same time, due to the sudden and real-time requirements of the voice, there is no dialing process similar to that of a fixed telephone

Embodiment Construction

[0023] Such as Figure 1 ~ Figure 5 As shown, the method for realizing network-wide broadcast voice in the Ad hoc radio network of the present invention includes the following steps:

[0024] (1) such as figure 1 As shown, the voice communication priority of each radio station is set, the data time slot is evenly allocated to each node, and then the synchronization network is established to establish an Ad Hoc network. In the process of synchronization networking, a certain radio node is preset as the master station, and other nodes are subordinate stations. Each station node adopts the time division multiple access (TDMA) mode, and the process of synchronizing the network is the process in which the master station sends a time stamp signal to each subordinate station to unify the entire network time. If the priority is not set in advance, the master station is the highest priority by default, and the other stations are the general priority. After synchronization, the channel i...

Abstract

The invention discloses a method for realizing all network voice broadcast in a multi-hop Ad Hoc radio station network. The technical scheme of the method is that an all network broadcast voice sender radio station sends voice through a voice time slot and records the voice at the same time; a receiver radio station sends and forwards an all network broadcast voice notice in the data time slot; aradio station which receives the all network broadcast voice notice and does not receive the voice sends an all network broadcast voice non-arrival notice; after receiving the all network broadcast voice non-arrival notice, the sender radio station sends the recorded voice to a node which does not receive the all network broadcast voice in the data time slot by using a multicast mode. Therefore, users in the Ad hoc radio station network can give commands conveniently and efficiently in the entire network, and the commands can be intuitively sent to all users in the network. The method is applied to the Ad Hoc radio station network.

Description

Technical field [0001] The invention relates to the field of wireless network access, in particular to a method for realizing whole-network broadcast voice in a multi-hop Ad hoc network. Background technique [0002] The currently widely used cellular mobile communication system is centrally controlled, and the operation of the network must be based on pre-built network facilities. These two characteristics make the cellular mobile communication system unsuitable for some special occasions. For example, rapid deployment and advancement of troops on the battlefield, rescue after an earthquake or flood. Communication in these occasions cannot rely on any pre-built network facilities, nor can it take a centralized control method based on robustness considerations. At this time, a special communication system is needed: the operation of this communication system cannot be based on any pre-built network facilities, it must be able to realize temporary and rapid automatic networking,...
