Embodiment Construction

[0059] This design is based on Altera's FPGA Stratix Ⅳ and Freescale's PowerPC Mpc8270 hardware platform's aviation data link networking network layer solution, which is applied in the field of aviation wireless data link networking. The present invention combines table-based and on-demand routing-driven forms, can support a network scale of 16 tactical formations and 32 nodes, has a complete node network entry-exit mechanism, and uses table-driven routing in the same tactical formation to ensure real-time On-demand driving routing is adopted between cross formations, which greatly reduces the average routing table entries of nodes, and relies on gateway nodes to forward routing applications "purposefully" rather than "blindly", reducing network flooding.

[0060] The aeronautical ad hoc network hybrid routing method based on tactical cooperative formation completes the establishment and maintenance of the neighbor table and routing table of each node in the same formation, and...

Abstract

The invention discloses an aeronautical ad hoc hybrid routing method based on tactical coordinated formations. The method comprises 1, the method for establishing and maintaining routings in the same formation; 2, the method of a node for sending a routing request message to a gateway when information is interacted between the formations; 3, the processing method of the node after receiving a routing response message sent by a gateway node; 4, the method of the node for maintaining the on-demand routing; 5, the method for establishing the gateway; 6, the method of for adding the node into the formation; and 7, the method for allowing the node to quit the formation. The method combines two routing driving modes including table driving and on-demand driving, the table-driven routing is used in the same tactical formation, and thus a real-time business requirement is ensured; the on-demand driving routing is used between the formations, so that average routing table entries of the node are greatly reduced, routing requests are forwarded in a purposeful manner instead of a blind manner based on the gateway node, and network flooding is reduced.

Description

technical field [0001] The invention belongs to the wireless self-organizing network technology of avionics information, and is a method for realizing the hybrid routing protocol (Routing Protocol) of the aviation ad hoc network based on the tactical cooperative formation for the aviation data link networking environment with high-speed topology changes, which is applied to aviation Wireless data link networking field. technical background [0002] Mobile Ad hoc Network (MANET) is a special wireless mobile communication network, which does not require support from fixed base stations, can realize distributed management without a center, can be organized temporarily, and is highly mobile. The routing protocol is one of the core technologies of the network layer of the aeronautical ad hoc network, which determines the network performance to a large extent. Considering that data link equipment is usually equipped on high-speed moving platforms such as aircraft and missiles, th...
