Automatic Relay Method for High Dynamic Ground-Air Network

Abstract

The invention discloses an automatic relay method of a high dynamic air-ground communication network. By adoption of the automatic relay method, the relay problem brought by the limited wireless bandwidth can be solved. The invention is implemented by the following technical scheme: an air node wireless transmission unit performs statistics on a respective average receiving signal to noise ratio of each adjacent node at the end of a statistical period; an air node protocol processing unit determines a connection state and a belonging access point of the present node according to the average receiving signal to noise ratio and a message receiving condition, generates node state information and sends the node state information to the access point through a wireless transmission unit; an access point protocol processing unit forwards the node state information to a center point through a wired transmission unit; and a center point protocol processing unit calculates the connectivity of the air node and the link capability between the directly connected node and the indirectly connected node, and allocates each indirectly connected node to a specific air relay node, and sends a calculated global topology information result to all access points via the wired transmission unit.

Description

technical field [0001] The invention relates to an automatic relay method suitable for high dynamic ground-air communication network. Background technique [0002] With the continuous development of aviation platforms, the demand for broadband ground-to-air communications is growing rapidly. It is an urgent and important task to establish a variety of data transmission links to meet the needs of various aviation platforms to perform different tasks. Space communication data transmission links and satellite nodes have characteristics such as high bit error rate, high delay, dynamic topology, and diverse bearer services, which make it difficult to achieve reliable and effective management of satellite network equipment and satellite nodes; on the other hand, traditional The satellite network management method based on the ground measurement and control station is no longer suitable for the development of satellite network management. Satellite communication has long delay, li...

Problems solved by technology

This method is flexible and has good topology adaptability, but it brings large routing overhead and implementation complexity to air nodes, slow convergence speed, and cannot solve the problems caused by the characteristics of high dynamic ground-air network multi-level transmission rate and so on. relay conundrum

[0010] Existing technical solutions either bring large control overhead, or have poor relay reliability, and cannot take into account the performance of both aspects, and cannot solve the relay problem caused by the severely limited wireless bandwidth of the highly dynamic ground-air network and the rapid change of the network topology. problem
