在新世代綠能網路中，合作式通訊已證實可透過使用中繼合作夥伴達到空間多工增益，並且可以有效的增加能源使用效率。但在真實的網路環境中，假設所有使用者皆協助合作傳輸是不合理的，特別是對能源有限制的行動裝置使用者。為了解決這個問題，過去曾提出一套應用名聲競拍賽局於綠色合作式通訊之資源分配機制，作者提出了一套名聲競拍系統，利用名聲系統導入了間接互惠的概念，進而激勵使用者參與或協助合作傳輸。但過去的研究中，並未分析系統所能達到的中斷效能而且也未提供一套有效的策略來協助使用者在名聲拍賣中適當的設定名聲值大小，以使其效能達到最佳化。因此，本篇論文利用中斷機率做為系統效能依據，提出一套數學分析模型，分析名聲競拍賽局應用於綠能合作式通訊所能達到之中斷效能。在此分析模型中，考慮了名聲值與中繼合作夥伴傳輸功率的關係，在瑞雷衰退統計模型下，我們推導出精確的中斷機率模型。並且，藉由電腦模擬驗證分析模型所求出的分析結果與電腦模擬數據相當吻合。此外，本篇論文也藉由分析結果，提出了一套有效率的方法來協助使用者在名聲拍賣中適切地設定名聲值大小。由數據結果可以顯示，提出的方法可以在保證使用者中斷效能需求下，最小化名聲值的消耗。

Cooperative communications with single relay selection is a simple but effective communication scheme for next-generation green networks. However, it is unrealistic to assume that all users in real-world wireless networks would be willing to participate in cooperative communications, especially if their energy resources are limited. To address this issue, a previous work proposed a reputation auction scheme to provide indirect reciprocity for stimulating user cooperation, but lacks a performance analysis and an efficient method for determining the reputation announcement. Accordingly, this thesis proposes a mathematical model to derive the outage probability performance for a reputation auction framework in the green cooperative communications. In this model, the relationship between the reputation value and the corresponding transmitting power are considered, and an exact outage probability of the system over Rayleigh fading channels is derived. The analytical results derived using this model agree with those obtained from computer simulations. Furthermore, this thesis presents a scheme to efficiently decide a reasonable reputation in the announcement process according to the analysis results. Numerical results show the proposed scheme can simultaneously minimize the reputation cost and guarantee user outage probability performance.
