NeTS: ProWiN: Wireless Spectral Interference and its Impact on Dynamic Network ConnectivityAward 0435389Dennis Roberson, Illinois Institute Of TechnologyAbstractThe increasing density of wireless devices and radiating sources generates significant aggregate interference adversely affecting network performance. There is a strong motivation to thoroughly understand the interference phenomenon and adaptively adjust a wireless network to mitigate its effect. The research objective is to codify the emission from several devices that produce electromagnetic interference in the 2.4 GHz (and potentially 5 GHz) unlicensed band.A three-prong methodology is employed: (1) development of a theoretical model of the interfering signal in the temporal and spectral domains; (2) the validation of the interference model via computer simulation; (3) physical experimentation to verify and enhance the accuracy of the previous results, which in turn augment the experimental work.For the devices considered, the interference temperature is determined as an outcome. The aggregate effect on wireless network throughput is measured and related to the interference temperature. These results suggest that techniques can be developed to improve network connectivity. Temporal, spatial, and spectral scales can be advantageously used in adaptive algorithms to flatten interference and assist in the development of underlay networks, such as ultrawideband.This research will have broad impact and allow the technical community to better understand how to use the available network resources. Network performance improvement can result in significant cost saving to the wireless industry. An important impact will be on U.S. government communication policy. The education and training of graduate and undergraduate students will be enhanced by this research. The results will be disseminated via public demonstrations, symposia, seminars, and publications.

网络：Prowin：无线光谱干扰及其对动态网络ConnectivityAward的影响0435389Dennis Roberson，Illinois Technologion of Technologion Abstracts，无线设备的密度不断提高，辐射源的密度增加，产生了重大的聚集干扰，从而对网络性能产生不利影响。 有强大的动力可以彻底了解干扰现象并自适应调整无线网络以减轻其效果。 研究目标是将几种在2.4 GHz（和潜在的5 GHz）无载带中产生电磁干扰的设备的发射编纂。采用了三个统计方法：（1）开发时间和光谱域中信号的理论模型； （2）通过计算机模拟对干扰模型的验证； （3）物理实验以验证和增强先前结果的准确性，从而增强了实验工作。对于考虑的设备，将干扰温度确定为结果。 测量了对无线网络吞吐量的骨料效应，并与干​​扰温度有关。 这些结果表明，可以开发技术来提高网络连接。 时间，空间和光谱量表可以有利地用于自适应算法中，以使干扰和帮助开发诸如UltrawideBand之类的底层网络。这项研究将产生广泛的影响，并允许技术社区更好地了解如何使用可用网络资源。 网络性能的改善可以为无线行业节省大量成本。 重要的影响将是美国政府传播政策。 这项研究将增强研究生和本科生的教育和培训。 结果将通过公开演示，研讨会，研讨会和出版物来传播。
