摘 要: 在多源多中继无线网络环境下,提出了实现中继选择和功率控制的分布式算法ARSPC。ARSPC算法将用户和中继节点的关系建模为多买家多卖家的拍卖模型,通过加价式拍卖分布式实现了用户对中继的选择和中继发送功率的控制。理论证明和仿真结果都验证了在基本价格增量足够小的条件下,ARSPC算法收敛的结果是帕累托最优。 A distributed relay selection and power controlling scheme ARSPC was proposed in the wireless environment of multi-source and multi-relay. ARSPC scheme modeled the relationship of user and relay nodes as a multi-buyer multi-seller auction, and realized the relay selection and relay power controlling by ascending auction. Both theory analysis and simulation results prove ARSPC can converge to pareto efficient result under conditions of a basic price increment which is small enough.
