Abstract

The invention discloses a channel allocation method based on a cognitive radio network, equipment and a storage medium. The channel allocation method comprises the following steps: (1) determining a coding mode and generating an initial group, (2) determining a fitness function and calculating the fitness value of each individual in the group, (3) calculating the average fitness and the maximum fitness of the group, sorting the groups according to the fitness values and dividing the groups into two groups, (4) crossing the groups, (5) carrying out group variation, (6) updating the groups, and(7) judging iteration termination conditions. According to the invention, a channel allocation model with maximized network throughput is established based on a cognitive wireless network; and a self-adaptive genetic algorithm is used for solving to obtain a channel allocation result with maximum network throughput, so that the problems of single method and communication congestion in marine fishing boat channel allocation are solved, and better guarantee is provided for work coordination, emergency rescue and the like among marine fishing boats.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a channel allocation method, device and storage medium based on cognitive wireless networks. Background technique [0002] With the continuous development of modern electronic communication technology, data interaction at sea is becoming more and more frequent, such as data interaction between ship electronic equipment, data interaction between ships and information centers, etc. These data interactions are all carried out through marine radio, and its performance directly affects the quality of data communication . [0003] When the ultrashort wave communication network of marine fishing boats divides the frequency band of fishery communication, the frequency band of fishery ultrashort wave communication is divided into multiple independent channels. The division and allocation method is single, resulting in signal congestion in some channels and a decrea...
