| 摘要: |
| 为了促使无线网络中的“自私”节点参与合作，提出了谈判解协作带宽分配（CBA）策略，解决了节点间采用交换带宽资源协作传输，彼此以多大带宽中继对方数据的问题。首先，将两个节点的协作带宽分配问题建模为合作博弈中的谈判过程；之后，采用拉格朗日乘数法得到两个用户的纳什谈判解（NBS）协作带宽分配；其次，提出了一种新的Kalai-Smorodinsky谈判解（KSBS）协作带宽分配策略；最后，对两种谈判解协作带宽分配策略的公平性进行了研究。仿真表明，KSBS协作带宽分配策略和NBS协作带宽分配策略对提升用户效用的作用基本相同，但KSBS策略比NBS策略更为公平。 |

| Abstract: |
| To promote the selfish nodes of wireless networks to participate in cooperative communication,the cooperation bandwidth allocation (CBA) strategies based on bargaining solutions are proposed. The proposed strategies solve the problem that how many bandwidth the nodes should share with each other in cooperative communication. Firstly,the problem of CBA is modeled as a bargaining process in cooperative game,and then the solution of CBA based on Nash bargaining solution (NBS) is obtained by adopting Lagrange multiplier method. Secondly,a new strategy based on Kalai-Smoriodinsky bargaining solution (KSBS) is raised. Finally,the fairness of CBA based on NBS and KSBS is studied in detail. Simulation results represent that the proposed KSBS-based CBA has the similar performance with the NBS-based CBA in term of users’ utility,but has the fairer performance. |
