Successful proliferation of wireless technologies in the past decade was led by multiple and heterogeneous technologies (e.g., WiFi, Bluetooth, and ZigBee) to accommodate diverse application requirements including system reliability, timeliness, and energy usage. However, wireless devices and their non-cooperative behavior lead to critically inefficient utilization of scarce wireless spectrum. This project develops a collaboration framework taking a clean-slate approach called Cross-technology Communication (CTC) - enabling message exchange between heterogeneous wireless technologies (e.g., Bluetooth and WiFi). The project aims to achieve two goals: (i) address resource under-utilization to bring significant cost reduction in network operation, and (ii) enable unique and advanced network functions via collaboration among heterogeneous entities with different capabilities. The impacts of this project will be further amplified by 1) embedding the technology on massive off-the-shelf systems via collaborations with major industry players; 2) improving curriculum development with enhanced course projects; 3) disseminating research results through high-profile tutorials and open-source sites; 4) raising interest in technology among K-12 students and under-represented minority groups through outreach activities including open houses; and 5) supporting talented female and minority PhD students. The project departs from the extensive studies in literature that commonly take implicit spectrum sharing approaches, to uniquely propose an explicit approach by enabling CTC. It enables cross-technology collaboration to bring advanced services, essentially exploring the bright side of coexistence. To achieve the goal, the project includes in-depth systematic study on CTC, contributing novel designs across multiple domains including: 1) extensive studies on empirical measurement and simulation to reveal the practical and theoretical limits of CTC capacity; 2) exploration of CTC design space to achieve gains in throughput, Quality of Service, and compatibility; 3) building scalable and reliable heterogeneous networks via CTC; and 4) CTC-enabled services benefiting from collaboration between cross-technology channel coordination, time synchronization, localization, and energy management.

在过去十年中，无线技术的成功扩散是由多种和异质技术（例如WiFi，蓝牙和Zigbee）领导的，以适应各种应用程序要求，包括系统可靠性，及时性和能源使用。但是，无线设备及其不合作行为导致对稀缺无线频谱的严重利用效率低下。该项目开发了一个协作框架，采用一种称为跨技术通信（CTC）的清洁方法 - 在异质无线技术（例如蓝牙和wifi）之间启用消息交换。该项目旨在实现两个目标：（i）解决利用不足的资源以降低网络操作的大幅成本，（ii）通过具有不同功能的异质实体之间的协作来启用独特和高级的网络功能。 1）通过与主要行业参与者的合作将技术嵌入大规模现成的系统中，将进一步扩大该项目的影响； 2）通过增强的课程项目改善课程开发； 3）通过备受瞩目的教程和开源站点来传播研究结果； 4）通过包括开放式房屋在内的外展活动，在K-12学生和代表性不足的少数群体中提高对技术的兴趣； 5）支持才华横溢的女性和少数民族博士生。该项目偏离了通常采用隐式频谱共享方法的文献中广泛的研究，从而通过启用CTC唯一提出了一种明确的方法。它使跨技术协作能够带来高级服务，从本质上探索了共存的光明方面。 为了实现该目标，该项目包括对CTC的深入系统研究，跨越了多个领域的新设计，包括：1）有关经验测量和模拟的广泛研究，以揭示CTC容量的实际和理论限制； 2）探索CTC设计空间，以实现吞吐量，服务质量和兼容性的提高； 3）通过CTC构建可扩展且可靠的异质网络； 4）跨技术渠道协调，时间同步，本地化和能源管理之间的协作中受益于CTC的服务。
