Embodiment

[0034] The present invention provides a wireless ad hoc network routing information acquisition method, including:

[0035] (1): According to the coverage area and number of nodes of the wireless ad hoc network, and the number and range of nodes that the routing calculation node can cover, the wireless ad hoc network is divided into one or more subnets, and each subnet is provided with a routing calculation node;

[0036] Among them, routing computing nodes can be divided into mobile and fixed routing computing nodes. Mobile routing computing nodes can be carried and moved by drones, etc., and fixed routing computing nodes can be realized by elevating the nodes; if the wireless The ad hoc network node is in a non-mobile state, and the routing calculation node can perform a short-term flight or temporary elevating mode. For the wireless ad hoc network node in the mobile state, the network topology will often change, and the routing calculation node needs to be periodically Prov...

Abstract

The invention discloses a method for obtaining routing information of a wireless ad hoc network. The invention provides all network nodes with the topology structure of the entire network and routing information between nodes by introducing hierarchical routing calculation nodes in the wireless ad hoc network, thereby improving the The routing convergence speed of distributed nodes; the routing information acquisition method proposed by the present invention assists network nodes to quickly obtain routing information between nodes in the entire network, and realizes the rapid convergence of distributed node routing with a small signaling overhead. Network nodes can select the optimal transmission route for multi-hop transmission according to the obtained routing information, which improves the transmission quality and expands the network coverage.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for acquiring routing information of a wireless ad hoc network. Background technique [0002] Wireless ad hoc network is a new type of wireless network architecture completely different from traditional wireless cellular networks, including multiple communication nodes. The nodes in the network are all equal, and each node and each communication node has the functions of sending, forwarding and receiving, so any two nodes in the network can communicate through direct links or multi-hop links. Compared with traditional cellular networks, wireless ad hoc networks do not need to rely on infrastructure, and have the advantages of flexible and simple networking, high network reliability, and large coverage. They are widely used in public security, military battlefields, post-disaster reconstruction, and first aid missions. [0003] Compared with the traditiona...
