The explosion of both wireless technologies and applications as well as the increasing number of radios and frequency bands available demand an understanding of in-field performance to design the next generation of wireless systems. Complex channel properties such as multipath, delay spread, and Doppler effects prevent even the most complex channel models from exactly characterizing repeatable in-situ behavior. Abstract models of devices and energy storage, as well as emerging paradigms such as energy harvesting enabled systems, make estimation of system performance and lifetime quite challenging unless supported by field experiments.
To better understand the potential of novel paradigms and ideas, it is therefore imperative to evaluate these ideas in the field via empirical measurement. While analytical and simulation-based approaches are useful, they are often limited by the simplistic modeling of the wireless protocols and devices and by the varying and error-prone wireless channel. Even slight misunderstandings can cause drastic performance differences in various research avenues from cognitive spectral sensing to spatial reuse in large-scale network planning to lifetime estimation as well as estimating the amount of tasks which can be performed by Internet-of-Things devices. As a response to these limitations, the need for experimental wireless network measurements has gained wide recognition in the networking research community.
WiNMeE 2014 is the tenth edition in the International Workshop on Wireless Network Measurements and Experimentation series that began in 2005, and is intended to bring together researchers in the field of experimental wireless networking and serve as a forum for discussing advances and challenges in experimental wireless network measurements and experimentation.
Keynote: Dynamic Spectrum Access: From Connecting Rural Africa to Finding the Next White Space Opportunity
To reach the remaining billions of unconnected people, we need additional spectrum. However, most of the prime spectrum has been allocated by the regulatory agencies. For the past 10 years, we have been exploring the use of Dynamic Spectrum Access as a paradigm to operate in unused portions of the allocated spectrum. In this talk, I will present two aspects of our work, First, on the TV white spaces, and how we are currently using the technology to connect villages and universities in Africa, and second, on a measurement framework to study spectrum occupancy from 30 MHz to 5 GHz, and how this framework can help unlock several new portions of spectrum for DSA, similar to the TV white spaces.
