The invention relates to an aircraft collaborative networking network layer routing protocol processing device and an implementation method. Each node comprises a topology discovery module which adaptively adjusts a detection period dynamically, adopts a variable detection broadcast detection method to carry out link sensing and discover neighbor nodes, and generates a neighbor table; a topology control module which is used for selecting a part of one-hop neighbor nodes of the node as topology control nodes, wherein each node broadcasts a neighbor table to the whole network through a topology control node, and after the node collects the neighbor tables sent by all the nodes in the network, a topology table of the nodes is generated; a routing algorithm module which is used for obtaining all effective routes from the node to other nodes of the whole network according to the topology table, and selecting an optimal route from the node to other nodes of the whole network from all the effective routes to form a route table; and a packet forwarding module which is used for reading the service data to be forwarded in the priority queue to execute forwarding according to the priority from high to low.
Description
technical field [0001] The invention relates to an aircraft cooperative networking routing device, which belongs to the technical field of wireless communication ad hoc networks. Background technique [0002] In modern warfare, high-speed aircraft achieve interconnection, cooperative operations, and precision strikes through Ad hoc networks. The network has the characteristics of a large number of nodes, highly dynamic changes in network topology, and mission priority guarantee requirements. The cooperative networking of high-speed aircraft is different from conventional Ad hoc networks. Its nodes are high-speed aerospace vehicles, and node units may join or exit the network at any time, resulting in frequent and rapid network topology changes and highly dynamic characteristics. In addition to meeting the basic data transmission functions of conventional self-organizing networks, the cooperative networking of high-speed aircraft must also consider the complex and changeable ...
