摘要：Dynamic spectrum access is a promising technique to use spectrum efficiently. Without being restricted to any prefixed spectrum bands, nodes choose operating spectrum on demand. Such flexibility, however, makes efficient and fair spectrum access in large scale networks great challenge. This paper presents a dynamic spectrum access decentralized approach. This approach is base on the game theory, mainly on the principle of Homo Egualis. There, it is assumed that operators are averse to unequal payoffs and act unselfishly, enabling a stable and sustainable community. An algorithm is proposed to solve the problems of inefficient use of spectrum and fair dynamic access to the available resources in the unlicensed bands. Numerical results show the performance of this algorithm
