Problems solved by technology

There is such a problem in the prior art: the size of the sequence number is set here based on the priority made when the next hop is a single hop. For an ad hoc network, its distribution is a tree distribution. When the top node of the tree will When the information is transmitted to the leaf nodes, the distribution between each leaf node is scattered, so it is a complex multi-hop distribution. The size of the sequence number alone cannot be the first selection factor for priority transmission. It is possible that the sequence number is small but Its branches are longer, and the next hop is closer to the root node (that is, the node within the wireless communication range of the base station in the wireless ad hoc network), that is, there is a situation where the node has more priority for communication; the serial number broadcast by the node is monotonically increasing Even number, when node B finds that the route to node D (routing sequence number is s) is interrupted, node B broadcasts a routing information, notifying that the sequence number of the route becomes s+l, and sets the number of hops to infinity, so , the routing table of any node A that sends information through B includes an infinite distance, this process until A receives a valid route to D (the route sequence number is s+1-1)
DSDV requires the routing table to be updated frequently, which still consumes energy and network bandwidth when the network is idle
Once the network topology changes, a new serial number will be generated; therefore, standard DSDV cannot be applied to rapidly changing networks, so it is very important to provide an improved DSDV routing protocol for ad hoc networks

[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...

Abstract

The present invention requests protection of an ad hoc network communication method and an ad hoc network communication system. The ad hoc network communication system includes a plurality of wireless nodes for networking, a communication base station, and a cloud server, and a single hop is performed between the wireless nodes. Information transmission, when a wireless node is within the communication radius R of the communication base station, the wireless node within the communication radius R transmits the information wirelessly to the cloud server through the communication base station, and returns the information through the cloud server and transmits the information in the wireless Transmission between nodes to realize self-organizing network communication. The improved destination station number distance vector DSDV protocol is used for networking between the wireless nodes. The main improvement is to combine the traditional destination station number distance vector DSDV protocol to build a multi-tree topology To carry out networking, and the nodes exchange information with their adjacent nodes through the RIP routing information protocol, including the following steps: initialization steps; steps for establishing routes between nodes; priority assignment steps; the higher the transmission priority, the priority selection This route performs data transmission and realizes networking communication.

Description

technical field [0001] The invention belongs to the technical field of communication, and specifically belongs to an ad hoc network communication method and an ad hoc network communication system. Background technique [0002] The wireless ad-hoc network is composed of nodes and is an autonomous, multi-hop network. The entire network has no fixed infrastructure and can be used when the existing network infrastructure (such as base stations, APs (Access Points)) cannot be used or is inconvenient. In the case of , it provides intercommunication between nodes. Due to the limited transmission power and wireless coverage of nodes, if two nodes that are far away from each other want to communicate, they must use other nodes to forward packets. In this way, a wireless multi-hop network is formed between the nodes. Mobile nodes in the network have routing and packet forwarding functions, and can form any network topology through wireless connections. A wireless ad hoc network can ...
