Hypergraph-based shortwave sky wave frequency cooperative competition method

Abstract

The invention relates to a hypergraph-based shortwave sky wave frequency cooperative competition method. The method comprises the following steps: acquiring an available frequency set through the way of the combination of the frequency long-term prediction and real-time perception based on the cooperative competition thought, a node participating the competition acquiring the information of the node competing the frequency with each other through the simple frequency competition statement, the competition statement reply, the frequency occupation statement, the occupation confirmation and like message transmission, accordingly, establishing the frequency cooperative competition hypergraph, defining the negative influence of the current node frequency competition to the competitor node competing the frequency as the negative influence factor so as to performing the frequency competition in the principle of meeting the own communication requirement and having the minimum influence to other nodes; the communication requirement of the node participating the competition is supported, and the total throughput capacity of all nodes participating the competition is improved. Through the adoption of the method disclosed by the invention, the distributed frequency cooperative competition can be realized through simple information interaction, and the optimal utilization of the shortwave sky wave frequency is facilitated.

Description

[0001] Yao Fuqiang, Zhang Jianzhao, Zhao Hangsheng, Yang Jian, Cao Long a technical field [0002] The invention relates to a method for improving the frequency utilization rate of short-wave sky waves, in particular to a short-wave frequency cooperative competition method based on a hypergraph, which belongs to the field of wireless communication. Two background technology [0003] The short-wave frequency band can not only use ground waves to achieve short-range communication, but also use sky waves to achieve long-distance communication through ionospheric reflection. It is the earliest wireless communication method invented and used by human beings. advantage. After more than 100 years of development, shortwave communication technology has made great progress in frequency prediction, channel modeling, adaptive frequency selection and equipment. The developing fourth-generation shortwave automatic link establishment technology supports stations to flexibly select data ra...
