Innovative use of wireless devices such as smartphones in various mobile applications has exacerbated the congestion over cellular spectrum. On the other hand, many licensed spectrum blocks are left unused. Although cognitive radios (CR) technology has emerged as an enabler for unlicensed users to opportunistically access the unused licensed spectrum, most previous works commonly assume that each user is equipped with a CR which can operate across a wide range of spectrum. This may be possible in theory, but may not be practical for light-weight devices such as cell phones. How to effectively utilize the CR technology to build more flexible networks so that even non-CR capable devices can benefit from the opportunistic access to the unused spectrum is therefore in dire need.In this project, the PIs propose a novel cognitive mesh assisted cellular network (CMCN) and investigate: 1) the architectural design of CMCN so that unoccupied licensed spectrum can be efficiently utilized and non-cognitive cellular devices can benefit from the CR technology, 2) spectrum and energy efficient CR mesh router placement under uncertain spectrum availability, 3) how to construct a fine-grained spectrum map to facilitate efficient spectrum allocation and intelligent traffic delivery, and 4) experimental validation and implementation for the proposed design. The research outcome provides a viable solution to the spectrum congestion in cellular systems. Moreover, with this flexible architecture, telecommunication industries can be rejuvenated with new innovations, leading to further development of cellular networks with high capacity and better support of new applications such as mobile healthcare, which has significant impact on individuals' lives and further provides greater opportunities for job creation and economic growth. The results of the project will be disseminated through publications and presentations. Finally, this project will actively recruit and train minority students for the future workforce and mentor junior faculty.

在各种移动应用中，无线设备（例如智能手机）的创新使用加剧了细胞光谱的拥堵。另一方面，许多许可的光谱块未使用。尽管认知无线电（CR）技术已经成为使无执照的用户机会访问未使用的许可频谱的推动者，但大多数以前的作品通常都认为每个用户都配备了可以在各种频谱上运行的CR。从理论上讲，这可能是可能的，但对于诸如手机之类的轻质设备可能不实用。 How to effectively utilize the CR technology to build more flexible networks so that even non-CR capable devices can benefit from the opportunistic access to the unused spectrum is therefore in dire need.In this project, the PIs propose a novel cognitive mesh assisted cellular network (CMCN) and investigate: 1) the architectural design of CMCN so that unoccupied licensed spectrum can be efficiently utilized and non-cognitive cellular设备可以从CR技术中受益，2）在不确定的频谱可用性下的光谱和节能的CR网格路由器放置，3）如何构建细粒光谱图以促进有效的光谱分配和智能交通，以及4）4）实验性验证和实施拟议的设计。该研究结果为细胞系统的光谱充血提供了可行的解决方案。此外，借助这种灵活的建筑，电信行业可以通过新的创新恢复活力，从而进一步发展具有高容量和更好地支持新应用（例如移动医疗保健）的蜂窝网络，这对个人的生活产生了重大影响，并进一步为创造就业机会和经济增长提供了更大的机会。该项目的结果将通过出版物和演示进行传播。最后，该项目将积极招募和培训少数民族学生为未来的劳动力和导师初级教师。
