[0083] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:
[0084] Such as figure 1 Shown, the real-time multicast method in a kind of wireless multi-hop network designed by the present invention is characterized in that the method comprises the following steps:
[0085] Step (1): Use the Multicast Announcement control packet to initialize the network as a mesh network;
[0086] Step (2): Assess the current network conditions and obtain all required network parameters;
[0087] Step (3): According to the current network conditions and the real-time requirements of the business, adaptively select the network coding or forward error correction coding mechanism, and dynamically adjust the coding parameters;
[0088] Step (4): The core node packs the real-time service data stream into groups, performs coding operations on each group block according to the selected coding mechanism and coding parameters, and t...
