摘要： An unrealistic preset condition exists in the cache-assisted relay system, namely that the social attributes of all nodes are highly overlapping and similar. In practice, however, this prerequisite is frequently not fulfilled because nodes exhibit a certain degree of selfishness. This paper, therefore, proposes a cache-assisted relay selection algorithm based on incentive cooperation to resolve the problem of system performance degradation precipitated by differences in the social attributes of nodes in cache-assisted networks. By incorporating the contribution of nodes to the system, nodes with poor social attributes are encouraged to participate in optimizing feedback effects actively. Nodes with high competition function values have a higher priority for information storage and transmission, improve the participation of low-attribute nodes, and attenuate the impact of channel changes, thereby enhancing network sustainability and system efficiency.(c) 2022 Elsevier B.V.
