An Priority-Based Flow Control Scheme with Utility Maximization in the Ad Hoc
Wei Ding · Microelectronics & Computer · 2008
An optimal distributed rate control 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 convergence performance.
