ABSTRACT : 5G wireless communication networks are expected to fulfill the demand for higher data rates, lower latency, and/or massive connectivity of a growing number of users/devices exploiting a variety of wireless applications. This envisioned rapid increase in the use of wireless services lead the wireless research community to start looking at new technologies to address problems related to the radio-frequency (RF) spectrum exhaustion. This includes the development of (i) new techniques and concepts such as massive multiple input multiple output (MIMO) systems and heterogeneous networks to improve the spectral efficiency at the link and network layers, respectively, and (ii) novel schemes to better utilize the unregulated bandwidth in particular in the upper millimeter wave, THz, and optical portion of the spectrum. This talk will first go briefly over the vision and goals of 5G wireless communication networks. Then it presents some of these emerging enabling technologies that need to be developed to pave the way towards the successful roll-out and operation of these future wireless networks. Finally, the talk offers at the end an overview of some of the recent results in the areas of massive MIMO systems, heterogeneous networks, and optical (Li-Fi) wireless communication systems.

TITLE : Autonomous self-powered and self-calibrated Microsystems for IoT applications
“Autonomous Microsystems” refers to smart electronic systems that are able to sense, process and transmit useful information from the environment while being completely autonomous by harvesting readily available solar, thermal or kinetic ambient energy. Deployed in IoT applications, these smart devices are able to monitor water leakage in a water pipe, blood pressure in human body, temperature of frozen food items, but also humidity, air and water quality in intelligent buildings and smart cities. The design of “autonomous Microsystems” must take into consideration a number of challenging IoT constraints such as low cost, self-calibration to minimize human intervention, and self-power generation to replenish depleted energy resources. Silicon based technology is the only alternative solution offering single-chip solutions featuring the best trade-off in terms of cost/performance and enabling large scale integration and mass volume production leading to large scale deployment of “autonomous microsystem” devices in various emerging IoT applications with minimal human intervention.
This talk will present enabling technologies for IoT sensing addressing key issues related to power consumption, energy harvesting and calibration of “autonomous Microsystems”. Three case studies will be presented, namely: (i) smart vision systems with energy harvesting capabilities, (ii) Batteryless temperature sensing for passive RFID applications and (iii) olfactory sensors with self-calibration capability. The talk will cover state-of-the art technological developments in this area, and outline existing challenges as well as emerging new opportunities for research and innovation in this rapidly growing field. The conclusion of the talk will discuss whether “autonomous microsystems” are becoming a reality or is just another engineering dream idea.

Among the new specifications of the future 5G wireless communication era, communications between machines reveals new technical challenges to take up. Radio access for IoT, or Wireless Sensor Networks, are among the most popular applications of machine-type communications. They are to be deployed where wired communications are lacking and where the energy distribution network is hardly available. Hence, most of the transmitters are battery-powered without any chance to be changed. In this context, how to save the energy consumption in order to increase the battery lifetime as long as possible?
On the physical layer, several new waveforms are competing for the upcoming 5G standardization, all of them being based on filtered multi-carrier modulations. However, the important signal peak power exhibited by multi-carrier modulations has a huge impact on the battery life and should prevent their implementation on the uplink. This talk will show why continuous phase modulations (CPM) can be an interesting alternative to multi-carrier waveforms for IoT and Wireless Sensor Networks. Some issues raised when dealing with CPM will also be presented together with some perspectives on possible solutions.

We give an extensive state of the art review of different access control models, policies and concepts. Then, we define the four most dominant IoT domains application and analyze their security and privacy requirements. Subsequently, we highlight the pros and cons of traditional as well as recent access control models and protocols from an IoT perspective. We also evaluate in a qualitative and a quantitative way the most relevant IoT related-projects; which represent the majority of research and commercial solutions proposed in the field of access control conducted over the recent years (2011- 2016). Finally, based on our evaluation, we highlight the potential challenges and give hints of future research directions. Our presentation addresses a broad range of models, protocols and frameworks related to access control in IoT. The main goal is not only to analyze, compare and consolidate past research work but also to appreciate their findings and discuss their pertinence towards IoT.

Contemporary operating systems suffer from being enormous code bases,
riddled with bugs, still supporting legacy hardware (like floppy
drives). A common attack vector is based on unsafe memory operations -
lack of bounds checks (buffer overflows) and temporal memory safety
violations (double free, use after free).
But the environment changed: for security reasons, each service is
usually isolated in its own virtual machine, and the virtual machines
are scheduled by the hypervisor onto the physical hardware. The
requirements for operating systems changed, but most operating systems
are only extended to support more complex environments.
In this talk I will present a radical approach to operating systems
design: back to ring 0, starting from scratch. Programming language
technology has progressed since UNIX was written in C, automated memory
management is widely used, strong and static types are usable, and we
learned how to build reusable libraries and package those.
MirageOS is a library operating system written mostly in OCaml, a
functional and modular programming language. It targets hypervisors,
thus does not contain hardware-specific drivers, but generic drivers
(e.g. a VirtIO network driver). Each MirageOS application consists of
only those OCaml libraries required - why should my name server have
user management and a file system? The lines of code, and thus the
attack vectors, are drastically reduced. We already implemented various
common network protocols, such as HTTP, TCP/IP, TLS, DHCP.
I will explain the design and implementation of our TLS stack in more
detail, which separates the effectful bits from the protocol logic very
clearly, while preserving reasonable performance.
