 “Effective Use of Small Cells in Heterogeneous Radio Access Networks”


In this talk we discuss some very simple Radio Access Network configurations comprising one macro cell and one or two small cells, the latter being strategically positioned to absorb the traffic peaks that occur in portions of the area covered by the macro cell. We study these configurations with simple models, and we examine the system performance for variable parameter values, showing that some of the emerging behaviors can be critical, but can provide insight for the small cell deployment. In particular, we show that when the handover rate out of the small cells toward the macro cell increases, the blocking probability in the macro cell also increases, quickly reaching unacceptable levels. This can be a problem, since high handover rates correspond to limited dimensions of the small cell with respect to the macro cell, which is what is normally expected, unless the small cell is deployed in an area of very slow end user mobility.

“6G: The Terabit Wireless Internet Vision”


6G Vision. Every 10 years a new wireless generation emerges with new requirements and new deployment scenarios not addressed by the previous generation. But the time of generations is getting shorter as we saw from the shift from 4G to 5G. This talk will address the new 6G electromagnetic spectrum requirements, the new research challenges, the new user requirements and their impact. Most data happens in-door and not on the street. Data center, company offices and building, factories and government building produce and consume 80-90% of their data in-house and their wireless bandwidth is limited to Gigabit. To move them to Terabit speed in-door, 6G will look at the Terahertz frequency to address its unexploited spectrum (called the Thz Gap) for new uses and innovations. The vast and enormous cabling spagetti of data center can be replaced by Thz communication to name an example. Very large scale research projects have been awarded around the world with flagship projects such as the 6Genesis project in Finland with the vision to instill interest in research and industry attraction to validate with pilots such a promising new terabit scale wireless technologies. The China MIIT has launched its 6G Program in June 2019 to with working groups to investigate on the Thz communication. The US government has also launched a Thz initiative back in June.

“How to design smart sensors with environmental energy and real-time capabilities”


A growing number of applications (e.g. medical, automotive) involve many wireless devices that may be deployed in wide areas and possibly unattainable places. Such systems should be designed to function perpetually without any human intervention because either costly or impractical. As a consequence, energy harvesting technology has been an area of rapid development during the last decade. Energy harvesting is a technology that allows to capture unused ambient energy. It is converted into electrical energy which is used immediately or later through a storage unit for powering these devices which in addition to energy limitations have to cope with real-time constraints. Consequently, energy harvesting sensors need to be provided with specific real-time scheduling and power management facilities. This keynote addresses state of the art as well as our findings in real-time scheduling and processor activity management for energy harvesting small electronic devices such as autonomous sensors.


Maryline Chetto is a full professor at the University of Nantes (France). She is conducting her research at LS2N (Laboratoire des Sciences du Numerique de Nantes). She received the degree of Docteur de 3ieme cycle in control engineering and the degree of Habilite a Diriger des Recherches in Computer Science from the University of Nantes, France, in 1984 and 1993, respectively. From 1984 to 1985, she held the position of Assistant professor of Computer Science at the University of Rennes 1, while her research was with the Institut de Recherche en Informatique et Systemes Aleatoires, Rennes, France. Her main research interests include Scheduling, Fault-tolerance and Dynamic Power Management technologies for real time embedded applications. She is now studying energy harvesting systems that use renewable energy to power embedded devices.

“The IPv6 debacle: A cautionary tale for all technologists”


The Internet community has long known that the dominant network layer protocol, IPv4, could not scale to support the levels of Internet growth that became expected during the late 1980s and early 1990s, and yet the replacement protocol IPv6 has not achieved widespread use. This presentation argues that the dual-stacking transition technique did not adequately consult non-technical perspectives and as a consequence was always unlikely to succeed. This has led to the present-day situation in which the number of Internet-connected devices vastly outnumbers the address space, in which work-arounds or “kludges” are used to eke out more and more connectivity from the IPv4 address space, and in which Internet governance policies have been changed to allow markets in which IPv4 address space is traded between organisations to operate. And yet although these markets were expected to facilitate the movement of address space from highly-allocated to relatively lower-allocated economies – which are generally in developing countries – yet the limited evidence available suggests that address space is rarely traded across national boundaries. Are these policies effective? Are we repeating the mistake of not consulting diverse perspectives?”
