无线网络中共享FIFO业务的流量控制与调度

Flow Control and Scheduling for Shared FIFO Queues over Wireless Networks

Shanyu Zhou, Hulya Seferoglu, Erdem Koyuncu

摘要:

我们研究了无线网络中先进先出(FIFO)队列的性能。我们的特点的稳定区域的一般情况下,任意数量的FIFO队列,这是由一个无线介质,由任意数量的流共享。一般情况下,该系统的稳定区域是非凸的。因此,我们开发了一个凸的内界的稳定区域,这是可证明的紧在某些情况下。内界的凸性允许我们开发一个资源分配方案; dFC。基于dFC的结构,我们提出了一种随机流控制和调度算法:qFC。我们表明,qFC达到凸内界的最佳工作点。仿真结果表明,我们的算法显着提高了无线网络的吞吐量与FIFO队列,相比,著名的基于队列的流量控制和最大权重调度。

英文摘要:

We investigate the performance of First-In, First-Out (FIFO) queues over wireless networks. We characterize the stability region of a general scenario where an arbitrary number of FIFO queues, which are served by a wireless medium, are shared by an arbitrary number of flows. In general, the stability region of this system is non-convex. Thus, we develop a convex inner-bound on the stability region, which is provably tight in certain cases. The convexity of the inner bound allows us to develop a resource allocation scheme; dFC. Based on the structure of dFC, we develop a stochastic flow control and scheduling algorithm; qFC. We show that qFC achieves optimal operating point in the convex inner bound. Simulation results show that our algorithms significantly improve the throughput of wireless networks with FIFO queues, as compared to the well-known queue-based flow control and max-weight scheduling.
