Flexible resource allocation adaptive to communication strategy selection for cellular clients using Stackelberg game

摘要

In cooperative communication Networks (or cooperative cognitive radio networks), a source node usually recruits non-altruistic relays to execute cooperative communication with a target node, through compensating these potential relays with a fraction of its licensed frequency band. When a source node is far apart from a target node, it is difficult to achieve the desired transmission performance by cooperative communication. In this paper, a source node's communication strategy can dynamically be adjusted with help of a base station according to variation of wireless communication environments. Also, an appropriate relaying path can be constructed to replace a long-distance wireless link without demand of channel state information. Furthermore, following the proposed Stackelberg game-theoretic method based on three-party-cooperation, a base station can determine the preliminary division of a source node's licensed frequency band and the initial power allocation for all the relays in the same relaying path, while the source node and the related relays can dynamically adjust them respectively during data transmission according to information feedback.
