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.

过去十年，无线技术的成功发展是由多种异构技术（例如 WiFi、蓝牙和 ZigBee）引领的，以满足不同的应用需求，包括系统可靠性、及时性和能源使用。然而，无线设备及其不合作行为导致稀缺无线频谱的利用效率极低。该项目开发了一个协作框架，采用一种称为跨技术通信 (CTC) 的全新方法 - 实现异构无线技术（例如蓝牙和 WiFi）之间的消息交换。该项目旨在实现两个目标：（i）解决资源利用不足的问题，从而显着降低网络运营成本；（ii）通过具有不同能力的异构实体之间的协作来实现独特和先进的网络功能。该项目的影响将通过以下方式进一步放大：1）通过与主要行业参与者合作，将该技术嵌入到大型现成系统中； 2）通过加强课程项目来改进课程开发； 3）通过高调的教程和开源网站传播研究成果； 4) 通过开放日等外展活动提高 K-12 学生和代表性不足的少数群体对技术的兴趣； 5）支持有才华的女性和少数民族博士生。该项目与文献中通常采用隐式频谱共享方法的广泛研究不同，独特地提出了一种通过启用 CTC 的显式方法。它使跨技术协作能够带来先进的服务，本质上是探索共存的光明一面。 为了实现这一目标，该项目包括对CTC进行深入的系统研究，在多个领域提供新颖的设计，包括：1）对经验测量和模拟的广泛研究，以揭示CTC容量的实践和理论极限； 2) 探索 CTC 设计空间，以实现吞吐量、服务质量和兼容性方面的收益； 3）通过CTC构建可扩展且可靠的异构网络； 4) 支持 CTC 的服务受益于跨技术渠道协调、时间同步、本地化和能源管理之间的协作。
