Problems solved by technology

[0003] In the prior art, Ad Hoc routing protocols are usually used to relay data between aircraft or between aircraft and ground base stations, but most of the existing Ad Hoc routing protocols are designed for general-purpose systems, and the protocols are complex and bulky. The aircraft network is characterized by a small number of nodes, poor network stability, high network dynamics, and narrow communication bandwidth. These characteristics make the use of existing Ad Hoc routing protocols for data relay, which will cause network congestion and high network bandwidth occupation. And the shortcomings of slow network status update

Abstract

The embodiment of the invention discloses a routing table updating method, device, aircraft and storage medium. The method is applied to a wireless network composed of multiple aircraft nodes and ground base stations, including: the aircraft node receives the transmission information of other nodes in the wireless network, and the transmission path description information is carried in the transmission information, and the transmission path description information is used to describe other nodes The transmission path with the ground base station, the transmission information includes: data packets and / or routing tables; the aircraft node updates the routing table stored locally in the aircraft node according to the received transmission information, and the routing table includes the monitored aircraft nodes and transmission paths Description. In the technical solution of the embodiment of the present invention, by designing a new routing protocol, effective wireless communication between the aircraft and the ground base station can be realized when the aircraft is flying at low altitude or flying beyond the visual range.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wireless communication, and in particular to a routing table updating method, device, aircraft and storage medium. Background technique [0002] At present, in order to expand the tasks and functions of the aircraft, the aircraft needs to change from the current single-flying single-control working mode to the multi-flying single-control working mode to form a highly dynamic aircraft network. Considering the rapid change of the topology of the network , there are nodes joining or leaving the network constantly, therefore, Ad Hoc network is the most suitable technology for establishing aircraft network. [0003] In the prior art, Ad Hoc routing protocols are usually used to relay data between aircraft or between aircraft and ground base stations, but most of the existing Ad Hoc routing protocols are designed for general-purpose systems, and the protocols are complex and bulky. Th...
