Aviation self-organized network routing method

Abstract

The invention discloses an aviation self-organized network routing method. The method comprises three stages: at a routing establishment stage, a source node queries whether the routing to a destination node is existent from the own recorded routing table, and initiates a routing request RREQ if the routing to the destination node is inexistent, when the RREQ is transmitted to the destination node, the destination node immediately produces routing reply RREP, and transmits back the RREP along the path of transmitting the RREQ, and the source node finishes the routing establishment after receiving the RREP; at a routing selection stage: an intermediate node records the information of a surrounding neighbor node transmitting the RREQ to the self in the RREQ table, wherein the information contains the minimum hop to the source node from the neighbor node; at a routing maintenance stage, the data is transmitted to some neighbor node when a data link of some node is broken, and the data iscontinuously transmitted on a standby path located by the neighbor node. The aviation self-organized network routing method disclosed by the invention can adapt to the aviation self-organized networkfeature, the network data transmission delay, the data packet arrival rate and like performances are obviously improved.

Description

technical field [0001] The invention belongs to the fields of wireless self-organizing network and electronic measurement and control, and in particular relates to an aviation self-organizing network routing method. Background technique [0002] In aeronautical communication, the widely used aeronautical communication network has certain disadvantages. For example, the direct communication effect of the aircraft is poor or even impossible to communicate directly. The air environment information sharing range of the aircraft detection is small. The ground control station and the intervention of communication satellites, etc. In order to solve these disadvantages, designing a wireless communication network with higher communication efficiency, better real-time performance, and adapting to the development model of future aviation communication networks has become an urgent task for civil aviation communication. In the field of military aviation, for many years, the Air Force h...

Problems solved by technology

[0006] The network characteristics of the aeronautical ad hoc network are wide airspace and fast node movement, resulting in frequent link breaks, so that the network frequently rediscovers routes, resulting in data delay and loss. In some places where the data delay is not high In some occasions, routing requests can be re-routed, but in applications such as commercial and military real-time transmission, data delays or even loss may cause huge losses

However, in AODVM multi-path independent routing, in order to establish independent paths, nodes need to store a large amount of network information, which makes the nodes overburdened and easily causes network paralysis
