Abstract

The invention discloses an efficient and fair dynamic spectrum allocation method which is applicable to interactive cognitive radio networks and comprises the following steps: on the basis of cooperative differential game theory, dividing the interactive cognitive radio network into different alliances and establishing an alliance-competition type architecture; setting that the interactive cognitive radio network has a plurality of cognitive users as well as the objective function and the payoff function of each cognitive user; and solving the objective function and the payoff function. The invention can effectively relieve the shortage of spectrum, improve the utilization ratio of spectrum, and take account of the fairness and the efficiency of spectrum use.

Description

technical field [0001] The invention relates to an efficient and fair dynamic spectrum allocation method for solving the problem of efficiency and fairness of dynamic spectrum allocation in a cognitive wireless network, and belongs to the technical field of dynamic resource division of a cognitive wireless communication network. Background technique [0002] Dynamic spectrum allocation is a distributed, multi-user multi-party dynamic game problem. When each cognitive user has limited resources, the process of occupying the spectrum can be regarded as a game process. This game includes the competition of communication time and frequency, etc. Every cognitive user wants to meet his communication needs to the greatest extent when using the spectrum. However, for the whole system, disorderly competition may lead to a decline in overall performance. Therefore, in order to improve the spectrum allocation efficiency of multiple cognitive users, it is necessary to allow each cognit...
