中文摘要：

以便充分利用异构的无线网络(HWN ) 的收音机资源并且为录像通讯支持家得多的用户的服务(QoS ) 的质量，一个带宽分配算法基于多收音机，存取在这份报纸被建议。建议算法采用一个改进分布式的普通收音机资源管理(DCRRM ) 能足够地减少发信号的开销的模型。这个计划能被划分成二个阶段。在第一个阶段，每个用户的候选人网络集合根据收到的信号力量(RSS ) 被获得。并且简单添加剂加权(锯) 方法被采用决定活跃网络设定。在第二个阶段，用途优化问题被录像通讯满足模型，的线性联合提出费用模型和精力效率模型。并且更多样地与 Lagrange 发现最佳的带宽分配计划方法和 Karush-Kuhn-Tucker (KKT ) 调节。模拟结果证明建议算法支持网络负担表演并且保证用户们在当前的状况下面获得最好的联合实用程序。

英文摘要：

In order to make full use of the radio resource of heterogeneous wireless networks（HWNs） and promote the quality of service（Qo S） of multi-homing users for video communication, a bandwidth allocation algorithm based on multi-radio access is proposed in this paper. The proposed algorithm adopts an improved distributed common radio resource management（DCRRM） model which can reduce the signaling overhead sufficiently. This scheme can be divided into two phases. In the first phase, candidate network set of each user is obtained according to the received signal strength（RSS）. And the simple additive weighted（SAW） method is employed to determine the active network set. In the second phase, the utility optimization problem is formulated by linear combining of the video communication satisfaction model, cost model and energy efficiency model. And finding the optimal bandwidth allocation scheme with Lagrange multiplier method and Karush-Kuhn-Tucker（KKT） conditions. Simulation results show that the proposed algorithm promotes the network load performances and guarantees that users obtain the best joint utility under current situation.
