针对异构无线网络合作传输的速率分配问题，在联盟效用函数中引入传输功耗，根据融合 － 分裂原则建立稳定的合作联盟，再用联盟形成博弈论对动态速率分配进行建模，进而提出了一种动态的速率分配算法． 为了最大化联盟收益，文中通过求导计算不同网络的传输速率． 这个基于融合 － 分裂的联盟形成和联盟内速率分配过程不断进行，直至业务流传输结束． 仿真实验表明，该算法可根据终端位置动态调整参数与传输的网络联盟结构，以低功耗获取高联盟收益．

Aiming at the rate allocation problem of the collaborative transmission in heterogeneous wireless networks，this paper introduces the transmission power cost into the coalition utility function，establishes a stable coalition on the basis of the merge-and-split rule and performs the dynamic rate allocation modeling on the basis of the coalition formation game theory． Then，a dynamic rate allocation algorithm is proposed． In order to maximize the coalition gain，the transmission rates in different networks are obtained through derivation． The above-mentioned process，which includes the merge-and-split-based coalition formation and the rate allocation in the coalition，continues until the end of traffic transmission． Simulation results demonstrate that the proposed algorithm can adjust the coalition structure dynamically in the transmission according to the terminal position and achieve a high coalition gain with a low power cost．
