Mobile ad hoc network communication method, device and system and storage medium

Abstract

The invention discloses a mobile ad hoc network communication method, device and system and a storage medium. The method comprises the following steps: receiving a networking signaling sent by an adjacent node of a receiving node; the networking signaling comprises a stable routing mark and hop count information, the stable routing mark represents a first path transmission state that the adjacent node reaches a certain appointed node in the ad hoc network, and the hop count information represents the forwarding times that the adjacent node reaches the certain appointed node in the ad hoc network; obtaining a second path transmission state from the receiving node to the specified node based on the received networking signaling; and updating the routing table of the receiving node according to the first path transmission state or the second path transmission state. According to the embodiment of the invention, the stable routing mark is introduced, during networking, each node broadcasts and transmits the own stable routing mark and constructs / updates the routing table, and the routing table of each node can obtain the most stable next-hop node which arrives at the appointed node, so that the connectivity rate between two long-distance nodes is improved.

Description

technical field [0001] The present disclosure relates to the technical field of private network communication, and in particular, to a mobile ad hoc network communication method, device, system and storage medium. Background technique [0002] The wireless ad hoc network can use the routing and forwarding function of mobile terminals to communicate without infrastructure, thus making up for the defect that no network communication infrastructure cannot be used. The main features are: dynamic change of network topology, multi-hop network, etc. Wait. [0003] There are two main ideas for the design of the relevant mobile ad hoc network routing protocols: 1) Adopt the routing principle of on-demand discovery, do not maintain the routing table by periodically broadcasting routing information, and only send requests to establish routes when a route needs to be established, The disadvantage is that the delay is large; 2) Using the principle of table-driven routing, the node broad...

Problems solved by technology

[0003] There are two main ideas for the design of related mobile ad hoc network routing protocols: 1) adopt the routing principle of on-demand discovery, do not maintain the routing table by periodically broadcasting routing information, and send a request to establish a route only when it is necessary to establish a route, The disadvantage is that the time delay is large; 2) Using the principle of table-driven routing, the node periodically broadcasts the routing packet information. When the node sends data, as long as there is a route to the destination node, the packet can be sent directly. The disadvantage is that between mobile terminals To exchange the content of the entire routing table consumes a lot of bandwidth; through research, it is found that the relevant mobile ad hoc network routing protocol cannot meet the scene requirements of emergency communication, especially not suitable for mobile terminal products with limited wireless bandwidth in the field of emergency communication, and cannot Meet the requirements to obtain accurate and available routing information in the shortest possible time, and can adapt to rapid changes in network topology, while effectively reducing the additional delay introduced and maintaining routing control information, or reducing the overhead of routing protocols, etc.
