    Project Summary

    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.

      Outreach and Education Activities for Broader Impact

      Course Development

      The research in this project is one of the main topics in the courses EEL 4598/5718: Computer Communications, EEL 6591: Wireless Networks, and EEL 6507: Queueing Systems and Data Communications at University of Florida, the split-level courses ECE 4813/6813: Communication Theory and ECE 4823/6823: Digital Communications, and the graduate courses ECE 8823: Advanced Topics in Wireless Networks and ECE 8990: Wireless Communications at Mississippi State University, and various courses offered at Texas Southern University. The research outcomes and network design methodologies developed in this project have been channelized into the classroom.

      Student Mentoring

      With the project support, we have been able to support graduate and undergraduate students to carry out fundamental research on cognitive radio networks and develop new technologies for next generation cellular systems and various mobile applications. Each week, each PI holds weekly research meeting to review the research progress and brainstorm new ideas. Moreover, through the Skype, the PIs could communicate with research progress and exchange research ideas. During the whole collaborative research project, both graduate students and undergraduate students (including minority students) could not only learn to work on research problems together, but more importantly are trained on how to learn, think, and present, from which they could learn how to teach as well. Some graduate students have successfully landed academic jobs to continue to train future work force. This collaborative research project is indeed fruitful and has trained strong professional work force in telecommunications.

      Research Dissemination

      Our major results have been disseminated through presentations and publications in meetings, conferences, and journals. A substantial quantity of the materials of this project have also been made publicly available here.
