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.

未来几年，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。 这种灵活性使他们能够找到多种网络协议并在它们之间进行自适应切换。 当SDR形成跨越多种网络标准的端到端多跳通信链路时，就构建了混合无线网络。 这些节点的关键任务是有效利用每一跳的可用网络接口将数据从源移动到目的地。 这项研究研究并开发了算法，以帮助 SDR 查找、识别和选择适当的接口来路由不同的流量流，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、重叠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。 PI 旨在通过举办短期研讨会来教育宾夕法尼亚州农村社区了解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萨斯奎哈纳县设计这样的网络，从而展示混合无线网络的更广泛影响。 研究成果将被传播并纳入各自机构的无线通信和网络课程中。
