Aviation ad hoc network routing method based on end-to-end quality parameters

Abstract

The invention provides an aviation ad hoc network routing method based on end-to-end quality parameters, and belongs to the field of aviation ad hoc networks. According to the method, quality parameters such as path remaining time, path bearing capacity, path time delay and path load utilization rate are mainly integrated, all quality parameter index values are subjected to weighted summation through an adaptive weight technology, a weighted result is used as an overall score of a path, and the path load utilization rate is calculated. And selecting the path with the highest total score as the routing path from the aircraft node to the base station. A base station adaptive broadcast mechanism is designed, and the base station can dynamically adjust the broadcast range of the base station, so that the base station can cover more source aircraft nodes. For the phenomenon that communication is interrupted due to the fact that the aircraft is possibly disconnected with a corresponding base station in the flight process, a threshold mechanism and a self-inquiry mechanism are introduced, and it is ensured that aircraft nodes can sense link changes in time and make decisions in time.

Description

technical field [0001] The invention belongs to the field of aeronautical ad hoc networks, and relates to an aeronautical ad hoc network routing algorithm based on end-to-end quality parameters. Background technique [0002] In recent years, with the continuous development of the aviation industry, the aviation market has undergone tremendous changes, and people's interest in providing Internet access in the cabin has increased. The cellular system provides direct communication between the aircraft and the ground station, but in areas where it is not easy to build base stations, such as deserts, oceans, etc., it is easy to cause link interruption; in order to meet the communication needs of these areas, the aircraft can use satellite relay The way to realize the communication between the civil aviation aircraft and the ground base station. Satellite-based space-based networks can provide a wide coverage area and high-speed data transmission, but satellite communications hav...

AI Technical Summary

Problems solved by technology

[0004] At present, there is no aeronautical ad hoc network routing method based on end-to-end quality parameters. This method comprehensively integrates quality parameters such as path remaining time, path carrying capacity, path delay, and path load utilization. Through adaptive weight technology, All index values ​​are weighted and summed, and the weighted result is used as the overall score of the path, and the path with the highest overall score is selected as the routing path from the aircraft to the base station
