中文摘要：
针对Ad Hoc中流竞争，提出了一种分布式节点的最优化速率控制机制。给出了基于流优先级的效用函数。以最大化网络整体效用为目标，通过运用对偶理论和梯度投影算法，给出了每一端到端流获得最优值的迭代机制，它能够保证高优先级流的QoS。仿真结果表明该机制可以使网络资源根据流优先级进行有效分配，并且具有很好的收敛性。
英文摘要：
An optimal distributed rate oontrol scheme is presented which is for the flow contention in the Ad Hoc network. In this paper,we define the flow utility based on the flow priority. In order to maximize the whole net utility, the end-to-end optimal flow rate can achieve through iterative scheme using duality theory and gradient projection algorithm. At the same time, the QoS of flow with high priority can be guaranteed. Simulation results show that the new scheme can effectively allocate the resource by flow priority and have good oonvergence performance.
