摘要:

总干扰度(TID)的概念传统上用于估计多无线电多链路无线网状网络(MRMC WMN)中的普遍干扰的强度。许多信道分配(CA)的方法,链路调度算法和路由方案已被提出的WMN完全依赖于TID估计的概念。他们专注于最小化TID,为网络创建最小干扰场景。在我们先前的工作[1]和[2]中,我们已经质疑TID估计的功效,然后提出了两个可靠的干扰估计度量,即,跨链路的信道分布成本(CDALcost)和累积X链路集权重(CXLSwt)。在这项工作中,我们评估这些干扰估计指标的能力,以取代TID的干扰最小化因素在CA计划上实现网格MRMC WMN。我们对ns-3进行了全面的评估,然后从结果得出结论,当CA方案使用CXLSwt作为底层干扰缓解函数(IMF)时,与使用TID作为IMF的CA相比,网络的性能提高了10-15%。我们还证实,CDALcost不是一个更好的货币基金组织比TID和CXLSwt。

英文摘要:

The notion of Total Interference Degree (TID) is traditionally used to estimate the intensity of prevalent interference in a Multi-RadioMulti-ChannelWirelessMesh Network (MRMC WMN). Numerous Channel Assignment (CA) approaches, linkscheduling algorithms and routing schemes have been proposed for WMNs which rely entirely on the concept of TID estimates. They focus on minimizing TID to create a minimal interference scenario for the network. In our prior works [1] and [2], we have questioned the efficacy of TID estimate and then proposed two reliable interference estimation metrics viz., Channel Distribution Across Links Cost (CDALcost) and Cumulative X-Link-Set Weight (CXLSwt). In this work, we assess the ability of these interference estimation metrics to replace TID as the interferenceminimizing factor in a CA scheme implemented on a grid MRMC WMN. We carry out a comprehensive evaluation on ns-3 and then conclude from the results that the performance of the network increases by 10-15% when the CA scheme uses CXLSwt as the underlying Interference Mitigation Function (IMF) when compared with CA using TID as IMF. We also confirm that CDALcost is not a better IMF than TID and CXLSwt.
