Ad Hoc网络中基于智能天线的包调度算法

内容简介：针对智能天线系统中数据包队列头阻塞和“聋节点”问题，提出一种新的数据包调度算法。根据智能天线的方向性网络配置矢量，将节点周边空间划分为干扰区域和自由区域，依次为待发队列中数据包的目的地址匹配可用的自由区域，进行数据传输。仿真结果表明，该算法能有效消除队列头阻塞和“聋节点”，从而提高Ad Hoc网络的吞吐量性能，降低网络时延。

Abstract：For the problem of Head of Line(HOL) blocking and deaf node in the smart antenna system, a novel packet scheduling algorithm is proposed. Based on the Directional Network Allocation Vector(DNAV), it divides the surrounding space of a tagged node into interference regions and free regions, and transmits packets selected in turn from the data queue if there is an appropriately free region. Simulation results show that the algorithm can eliminate the deaf node problem and resolve the HOL blocking efficiently, which can obtain higher throughput and lower network delay.
