Wireless MAC protocols have been traditionally deployed as monolithic, one-‐size-‐fits-‐all, standards. In contrast, flexibility and programmability of wireless devices appear crucial to foster innovation and customization, so as to accommodate the need of customers (and applications) for personalized delivery and quality of experience, and overcome performance limitations by smartly exploiting opportunistically available spectrum and resources in dense environments. Moreover, wireless protocols originally designed for general scenarios are now stretched so as to fit the very diverse needs of niche contexts and deployments (industrial automation, domotics, military, emergency, machine to machine, etc).
In this talk, we revisit very recent advances in the field of wireless MAC programmability. We specifically focus on programming approaches which do not require open source network interface cards, but still permit dynamic MAC protocol stack reconfiguration in negligible (sub-‐microsecond) time. This is accomplished by decoupling a set of ``dumb'' (hard-‐coded) primitives, from a third-‐party provided ``smart'' MAC protocol logic, provided in the form of (extensible) finite state machines which formally specify how such primitives shall be executed. We argue that such ideas and approaches, although technically different and relying on different abstractions, appear to enrich the wireless access domain with software-‐defined networking concepts that are today leading the data centers and wired networks innovation.
Giuseppe Bianchi is Full Professor of Telecommunications at the School of Engineering of the University of Roma Tor Vergata, current chair of the relevant Bachelor/Master teaching programme in Internet Technology engineering, and former chair of the Telecommunications and microelectronics PhD programme. His research activity, documented in about 180 peer-‐reviewed papers accounting for more than 9300 citations, spans several areas including wireless LANs, privacy and security, design and performance evaluation of broadband networks, network monitoring. His analytical models concerning the performance analysis of 802.11 WLAN networks are well known in the research community. He is editor for IEEE/ACM Trans. on Networking and Elsevier's Computer communication, and area editor for IEEE Trans. on Wireless Communications. He has (co-‐)chaired more than 10 international IEEE/ACM conferences/workshops, the next major one being IEEE Infocom 2014 (technical co-‐chair). He has been involved in several European funded project, with general and/or technical coordination roles for the projects FP6-‐DISCREET (privacy in smart environments), FP7-‐PRISM (privacy-‐preserving network monitoring), FP7-‐DEMONS (distributed network monitoring) and FP7-‐FLAVIA (programmable wireless systems).
Ilenia Tinnirello is Assistant Professor at the University of Palermo since January 2005. She received the Laurea degree in Electronic Engineering and the Ph.D. on Communications, respectively in April 2000 and February 2004. Her research activity has been mainly focused on wireless networks and in particular on: multiple access algorithms with quality of service provisioning; cross-‐layer interactions between access solutions and physical layer; mobility management and load balancing in wireless packet networks; methodologies for experimental characterization of wireless local area networks. She has been involved in various national and international research projects: project PRIN RAMON; project FIRB PRIMO, and project PRIN MIMOSA as unit coordinator. She has been technical coordinator of the FLAVIA EU FP7 Project.
