随着无线技术的不断发展，使用该技术的各种新兴应用将紧密交织在我们的日常生活中：无线传感器网络可以监控个人健康或关键基础设施。许多这些应用的可行性和成功关键取决于底层无线通信的可用性。随着无线网络日益普及，无线电干扰和干扰问题将不可避免，对无线服务的可用性构成严重威胁。 为了在无线网络的整个生命周期内实现连续和高可用的数据传输服务以支持无线应用，无线网络具有针对干扰和干扰的内置强大防御机制至关重要。该项目旨在开发一套全面的解决方案，以监测无线电环境，并在出现干扰或无线电干扰时快速恢复中断的服务。与传统技术（例如需要昂贵的新硬件的扩频）相比，所提出的技术涉及网络跨所有层协作地管理其资源以确保网络服务的可用性，从而利用现有的商品无线平台。通过与行业合作伙伴的互动，项目成果有望为未来网络架构中应对干扰提供指导。 该项目的教育部分旨在帮助学生应对无线网络中快速发展的技术所带来的挑战。这个项目的实验和设计部分将提高本科生和研究生？相关领域的教育。

With the continuing proliferation of wireless technology, a wide spectrum of emerging applications using this technology will be tightly interwoven into the fabric of our everyday lives: wireless sensor networks can monitor personal health or critical infrastructures. The viability and success of many of these applications critically hinges on the availability of the underlying wireless communication. As wireless networks become increasingly pervasive, the problem of radio interference and jamming will be inevitable, raising a serious threat to the availability of wireless services. To enable the continuous and highly-available data delivery services over the entire lifetime of wireless networks in support of wireless applications, it is crucial that the wireless networks have built-in strong defense mechanisms against interference and jamming. This project aims to develop a suite of holistic solutions that monitor the radio environment and provide quick recovery to interrupted services in case of jamming or radio interference. In contrast to traditional techniques, such as spread spectrum which requires costly new hardware, the proposed techniques involve networks to manage their resources collaboratively across all layers to assure the availability of network services, leveraging existing commodity wireless platforms. Through the interaction with industry partners, the project results are expected to provide guidance for coping with jamming in future network architecture. The educational component of this project seeks to prepare students to face the challenges of rapidly evolving technologies in wireless networks. The experimental and design components of this project will enhance both the undergraduate and graduate students? education in related areas.
