Cognitive radio network slave user combination price-fixing and resource distributing method

Abstract

The invention discloses a cognitive radio network slave user combination price-fixing and resource distributing method under an imperfect channel based on the non-cooperative game theory and belongs to the technical field of wireless communication, especially cognitive radio networks. On the basis that a cognitive radio network master user determines base price based on sub-channel activeness and slave users determine a paying strategy based on a sub-channel state, non-cooperative game modeling is carried out on all the slave users, based on slave user channel features, power is transmitted, and channel cost modeling effect is shared. By obtaining a game model Nash equilibrium solution by solving, a slave user optimized price-fixing and resource distributing strategy is obtained. The shared resource non-cooperative competitive relation and the resource sharing strategy of the multiple slave users in a cognitive radio network are considered comprehensively, effective guaranteeing of a slave user communication requirement and efficient sharing of cognitive network spectrum resources can be achieved, and spectrum resource deficiency is relieved.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to resource allocation and channel pricing methods in the field of cognitive radio. Background technique [0002] With the rapid development of wireless communication technology and the continuous growth of wireless application requirements, various communication applications have an increasing demand for wireless spectrum. The traditional fixed spectrum allocation method leads to fierce competition in some frequency bands and serious shortage of spectrum resources. At the same time, a large number of allocated spectrum in some frequency bands is not fully used, resulting in low spectrum utilization. In order to effectively improve the utilization rate of spectrum resources and alleviate the shortage of spectrum resources, cognitive radio technology using dynamic spectrum access mechanism has attracted extensive attention in recent years. [0003] The cognitive radio system ad...

Problems solved by technology

The above method only considers the secondary user channel and power allocation under the determined channel conditions, and does not consider the optimal resource allocation and pricing strategy when the primary user channel occupancy information cannot be fully known in the actual application scenario, and cannot realize the secondary user performance in the real application environment. optimization
