Problems solved by technology
The OLSR protocol is suitable for small-scale network scenarios. Although MPR nodes are used to reduce the number of flood messages, as the network scale increases and the number of hops increases, the routing protocol overhead increases exponentially, and the entire network is a flat structure. Each node needs to obtain the distribution of the entire network nodes, which is not conducive to the management of network permissions and routing ranges of different nodes in real situations
Moreover, under the condition of large-scale networking, the efficiency of establishing routing tables in OLSR protocol networking is low, the networking time is long, and the convergence of routing updates is slow.
[0003] In view of the low efficiency of the OLSR routing protocol in related technologies, no effective solution has been proposed yet

The invention relates to a hierarchical network routing method and system based on an OLSR routing protocol, computer equipment and a storage medium. The method comprises the steps that a gateway nodein a hierarchical network acquires node information of each node in the hierarchical network through packet broadcasting, a subnet list is determined according to the node information, the gateway node transmits the subnet list to an upper-layer network, and the upper-layer network node maintains upper-layer node routing information according to the subnet list. By adopting the method, the networking efficiency of the whole network can be improved, the convergence of the routing table can be accelerated, and the networking requirement can be better and faster met.
Description
technical field [0001] The present application relates to the technical field of communication, in particular to a layered network routing method, system, computer equipment and storage medium based on the OLSR routing protocol. Background technique [0002] Due to its self-organization and self-healing characteristics, MANET network is widely used in military communication and post-disaster emergency communication. Many routing algorithms and protocols have been proposed for MANET network, including on-demand routing protocol, active routing protocol and hybrid routing protocol. agreement etc. However, in the case of dynamic network topology changes caused by factors such as movement, interference, and complex terrain, how to adaptively select and use routes to ensure end-to-end service flow requirements has always been a hot research issue. Optimizing link state routing The protocol (Optimal Link State Routing, OLSR) is a table-driven link state routing protocol. Nodes up...
