[0031] Such as figure 1 As shown, an ad hoc network communication method is applied to a wireless ad hoc network communication system. The wireless ad hoc network communication system includes a plurality of wireless nodes for networking, a communication base station, and a cloud server. Among the wireless nodes When a wireless node is within the communication radius range R of the communication base station, the wireless node within the communication radius range R transmits the information wirelessly to the cloud server through the communication base station, and returns the information through the cloud server The information is transmitted between wireless nodes to realize ad hoc network communication. The wireless nodes use the improved Destination Station Numbering Distance Vector DSDV protocol for networking. The main improvement is that the traditional destination station numbering distance vector DSDV protocol is combined to construct The multi-tree topology is used ...

[0058] Second embodiment: the method for constructing a multi-tree topology can be replaced by: on the basis of the traditional destination station number distance vector DSDV protocol, a HELLO handshake network is established between each node, and each node connected to the router node in the HELLO handshake network The link increases the dormant state, and a shared spanning tree is selected on a given network topology, and the links on it are always in the working state to ensure network connectivity. Other links that are not on the spanning tree will enter if there is no traffic passing through In the dormant state, each router saves the routing table of the shortest path of the entire network path and the routing table of the corresponding spanning tree. For a data packet, the ingress router determines that the data packet adopts one of the paths according to the current link load, and adds a label identifier. The ingress router selects the corresponding routing table for ...

[0059] The third embodiment: certainly, except adopting method of the present invention to construct multi-tree topology, also can adopt Scribe (Scribe) method to construct multi-tree topology, adopt Scribe (Scribe) method to construct multi-tree topology Corresponding improvements need to be made, that is, adding uplink bandwidth information in the Scribe method. The characteristics of the multi-tree topology constructed according to the Scribe method are: first, if a node acts as an intermediate node in a subtree, then in Other subtrees can only serve as leaf nodes; secondly, the node ID (identification) is used as input, and the specific position of the node can be obtained by using the Pastry (Pastry) algorithm analysis.
[0060] Specifically, there are five nodes in the system, node A, node B, node C, node D, and node E, and the uplink bandwidths are 256K bits, 512K bits, 1M bits, 2M bits, and 4M bits respectively. Currently, a single substream requires The uplink bandwid...
