Design and Building an Opportunistic Communications Prototype with Spectrum Contention and Cascades
Abstract
Wireless technology had demonstrated its critical role to military communications as well as civilian economy, and the growth of wireless devices and wireless traffic have been astonishing. The huge number of devices along with Internet of Things (IoT) and massive traffic have pushed the demand to radio spectrum more intensified than ever. However, the radio spectrum is a limited resource and has become extremely precious due to both federal and commercial demands. The large gap between the supply and the demand for radio spectrum has motivated extensive research efforts to explore innovative spectrum sharing to realize the full potential of radio spectrum. The practice and experience in more than a decade have demonstrated that spectrum sharing is difficult. In particular, there is one major technical hurdle toward information assurance and its applications in both defense communications and product commercialization: spectrum cascades, which is unique in cognitive communications, and might result in catastrophic aftermath that is much more severe than jamming and interference. The main objective of this project is to design and build an opportunistic communication prototype based on software defined radio networks, which is an integral engineering effort. We plan to explore new understandings and take first-hand measurements of spectrum sensing, spectrum detection and switching, spectrum contention, and spectrum cascades under interference and jamming such that we are able to transform our fundamental results into practical applications and further broaden the impact on wireless network design and reliable, secure communications. This infrastructure prototype is expected to be an example of using the latest off-the-shelf radio products to deploy guidelines from theoretical studies, intelligent algorithms of spectrum discovery and scheduling, and a variety of wireless attack strategies. In addition, we will use a cloud server and mobile cloud user terminals to examine the cloud computing techniques, as well as single- and multi-hop communications based on opportunistic spectrum acquisition. Therefore, our prototype will be able to offer innovative, solid insights with well-designed, comprehensive and controllable experiments and cross-verification of theoretical studies, while facilitating our curriculum development and mentoring activities.
