Collaborative Research: NeTS-ProWIN: Multi-Tier Hybrid Wireless Networks

在接下来的几年里，芯片设计、功耗和电池技术的不断进步将导致软件定义无线电（sdr）的广泛部署。sdr利用可编程硬件模块来动态修改各种无线电子系统的功能。这种灵活性使它们能够找到并自适应地在多个网络协议之间切换。当sdr形成端到端、跨多种网络标准的多跳通信链路时，就构成了混合无线网络。这些节点的关键任务是有效地利用每一跳上可用的网络接口将数据从源移动到目标。本研究研究和开发算法，以帮助sdr找到、识别和选择适当的接口，在此接口上路由不同的流量流，同时有效地分配无线电资源。目标是在这些领域取得基础成果，以便对混合无线网络进行更广泛的研究。这项研究将对希望通过互连异构、覆盖无线系统来扩展网络容量和覆盖范围的商业和军事服务提供商产生影响。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介绍混合无线网络的好处，并为宾夕法尼亚州北部的一个农村社区Susquehanna县设计这样一个网络，来展示混合无线网络的广泛影响。研究结果将分发并纳入各机构的无线通信和网络课程。

In upcoming years, continual advances in chip design, power consumption, and battery technology will lead to wide deployment of software defined radios (SDRs). SDRs take advantage of programmable hardware modules to dynamically modify the functionality of various radio subsystems. This flexibility allows them to find and adaptively switch between several network protocols. A hybrid wireless network is constructed when SDRs form end-to-end multihop communication links that traverse multiple network standards. The key task for these nodes is to efficiently utilize available network interfaces at each hop to move data from source to destination. This research studies and develops algorithms to help SDRs find, identify, and select appropriate interfaces over which to route diverse traffic streams while efficiently allocating radio resources. The goal is to develop foundational results in these areas so that a broader investigation of hybrid wireless networks can then be pursued.This research will have impact on both commercial and military service providers who wish to extend network capacity and coverage by interconnecting heterogeneous, overlaid 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 and by designing such a network for Susquehanna County, a rural community in Northern Pennsylvania. Research results will be disseminated and incorporated into wireless communications and networking courses at the respective institutions.
