摘要
提出一个联合传输速率、链路的传输时间和链路速率的网络利用最大化模型(NUM),并用对偶分解理论设计该问题的分布式算法。目标是为了得到传输层的最优的端到端的源速率,物理层的功率以及MAC层资源的最优分配,从而使网络利用率达到最大的同时使所有链路的功耗最小。通过仿真实验,验证算法的可行性,能达到预期的目标。
Proposes a network utility maximization（NUM） model which jointly considers transmission rates, transmission time of a link and the link- rate. The goal is to find the optimal end to end source rates at the transport layer, optimal resources allocation which include the power of the physical and the other resource of the MAC, then achieves the trade-off between the network utility and power consume. The simula- tion results validate the feasible of the algorithms and attain the desired goals.
