mm-Wave WPAN中基于速率自适应的空间重用算法
首发时间:2014-11-27
摘要:为了提高毫米波无线个域网(mm-wave Wireless Personal Area Network)的空间复用增益,本文提出了一种基于速率自适应机制的空间重用算法(MLR,Maxi Link-Group Rate)。MLR利利链路间的干扰信息,并结合物理干扰模型确定的链路共存条件,可准确有效地找到具有最大速率总和的链路组,并使之被调度,从而达到增大空间复用增益的目的。仿真结果表明,该算法与基于协议干扰模型的盲选算法(Blind)和基于物理干扰模型的最大共存度算法(MCP)相比,具有更高的空间复用增益,且这样的优势会随着网络中节点数目的增加而更加明显。

Spatial Reuse Algorithm in mm-Wave WPAN with Rate Adaption
Abstract:In order to improve the spatial reuse gain in mm-Wave WPAN,a spatial reuse algorithm with rate adaption was finally proposed.named with Maxi Link-Group Rate,the algorithm using the information of links combined with the physical interference model to define link coexistence condition,with the condition,MLR can find the link set with maximum rate sum accurately and effectively.Simulation results show that MLR has a more excellent performance than Blind algorithm with protocol interference model and maximum coexistence possibility algorithm(MCP) with physical interference model,and the comparative advantage increases along with the sectoe number and node number.
Keywords: millimeter-wave wireless personal network rate adaption spatial reuse
