節省能源消耗來降低對環境的衝擊並推行以綠能的新世代寬頻無線網路已成為全球的共同目標。雖然，合作式傳輸已被證實可有效的減少能源消耗來達到綠能網路的效益，但是多數的研究簡單的假設在網路上的使用者皆有意願參與合作式傳輸。相反地，本篇研究將引入協同式社群網路，這樣的網路上皆是以最大化自身利益的自私使用者，為了激勵使用者促使合作進行，本篇論文根據社群與工程的觀點提供以名聲系統為基礎的方式促進使用者互助合作。並設計回合式代理拍賣方法進行名聲的分配與更新機制來達到有效的能源利用以及競爭公平性。最後，模擬結果展示了本篇論文以名聲系統方式提供合理的使用者參與合作，同時根據使用者的貢獻比例來減少能源消耗以達到公平。

Energy conservation and environmental protection have become global demands which drive the endeavor towards green next-generation broadband wireless networks. Although cooperative communication has been shown to greatly reduce energy consumption resulting in benefits for green wireless networks, most studies make a simplistic assumption that all nodes are always willing to collaboratively transmit. Conversely, this study introduces a community network for cooperative transmission, where nodes are selfish and want to maximize their revenue. To motivate user cooperation, this study provides a reputation system based on social and engineering perspectives. A clock-proxy auction is designed as the reputation allocation and update mechanism to achieve energy-efficiency and competitive fairness, which results in light signaling overhead. Simulation results show that the proposed reputation system leads rational users to participate cooperatively to significantly reduce energy consumption while promoting fairness, as users receive resources in proportion to their contribution.
