无线网络中,为了实现用户高效的数据传输,针对用户的有限理性特性,提出了一种基于图型演化博弈的动态频谱接入机制,而图型博弈可以较好地反映用户之间真实的博弈关系。同时设计了一种动态频谱接入算法和与之对应的动态方程以降低博弈的复杂度,而且能以较快的速度收敛到 Nash 均衡并获得较高的系统吞吐量和效用。理论证明该动态方程具有全局逐步稳定性,当用户发生局部的理性偏移时依然能够保证较快收敛和较小性能偏离。仿真对比验证了该机制的上述优势。
In order to realize efficient data transmission for users in radio networks
a dynamic spectrum access mechanism based on graphical evolutionary game was proposed for the bounded rationality characteristic of users
while graphical game can better reflect the actual game relationship among users.Meanwhile
a dynamic spectrum access algorithm and corresponding dynamic equation were designed for the mechanism to reduce the complexity of the game
and could converge to Nash equilibrium with faster speed and obtain higher system throughput and utility.Theoretical analysis showed that the dynamic equation was globally asymptotically stable
which illustrated that when user deviated because of bounded rationality and it was still able to guarantee faster converge and fewer performance deviation.Simulation comparison verifies the superiority above.
