NeTS-WN: Collaborative Research: Cognition, Collaboration, and Competition in Hybrid Wireless Networks

未来的无线网络被设想为几个现有的和新兴的无线网络的无缝集成。未来网络的关键促成因素是认知软件定义无线电（SDR），它利用可编程硬件模块来动态和自适应地修改各种无线电子系统的功能。本研究的目标是促进无线网络的无缝集成，其中从源发送到目的地的信息可以穿越属于异构底层网络的多个链路。由此产生的混合无线网络的设计和运行由未来软件定义无线电的三个特征决定：认知、协作和竞争。研究结果将展示具有内在竞争性的特别提款权（sdr）如何协同工作以了解当前的本地网络状况；（ii）利用这些信息在这些本地网络（和“非网络”）之间构建自适应链路和路由，从而满足端到端的服务质量要求。具体的研究成果将包括分布式、协作算法，以帮助频谱感知和混合无线网络形成中的认知sdr。这项研究将影响商业和军事服务提供商，他们希望通过互连现有和新兴的无线系统来扩展网络容量和覆盖范围。PIs的目标是通过提供短期研讨会，向宾夕法尼亚州农村社区宣传混合无线网络的好处，来展示其更广泛的影响。此外，将分发研究结果，并将其纳入各机构的无线通信和网络课程。

The wireless network of the future is envisioned to be a seamless integration of several existing and emerging wireless networks. A key enabler for this network of the future is the cognitive software defined radio (SDR) which takes advantage of programmable hardware modules to dynamically and adaptively modify the functionality of various radio subsystems. The goal of this research is to facilitate seamless integration of wireless networks where information sent from a source to a destination can traverse multiple links that belong to heterogeneous underlying networks. The design and operation of the resulting hybrid wireless network is determined by three characteristics of future software defined radios: Cognition, Collaboration, and Competition. Research results will demonstrate how inherently competitive SDRs (i) work together to learn about current local network conditions; and (ii) use this information to construct adaptive links and routes across these local networks (and "non-networks") so that end-to end quality of service requirements are met. Specific research outcomes will include distributed, collaborative algorithms that aid cognitive SDRs in spectrum sensing and hybrid wireless network formation.This research will impact both commercial and military service providers who wish to extend network capacity and coverage by interconnecting existing and emerging wireless systems. The PIs aim to demonstrate broader impact of hybrid wireless networks by offering short workshops that educate rural Pennsylvania communities on its benefits. Additionally, research results will be disseminated and incorporated into wireless communications and networking courses at the respective institutions.
