TITLE : « PHILAE, Are you talking to me? »
ABSTRACT : The Rosetta spacecraft arrived at comet Churyumov-Gerasimenko in 2014, going into orbit and releasing PHILAE lander to study the composition of its surface and learn more about how our solar system formed. The presentation will focus on the link between Rosetta and Philae and especially on the work done by CNES. The RF link devices are described to show how telemetry was used during the mission.

TITLE : « Beyond Duty Cycling: How Wake-up Radio Technology and Semantic Addressing Enable Very Long-lived Wireless Sensing Systems (Finally!) »
ABSTRACT: Emerging wake-up radio technologies have the potential to bring the performance of sensing systems and of the Internet of Things to the levels of low latency and very low energy consumption required to enable critical new applications. In this talk we provide advancements toward this goal by describing how combining the latest wake-up radio design and semantic addressing conjures to provide wireless sensor systems that can last decades. In particular, we first describe the design and prototyping of a wake-up receiver (WRx) and its integration to a wireless sensor node. Our WRx features very low power consumption (<1.3uW), high sensitivity (up to -55dBm), fast reactivity (wake-up time of 130us), and semantic addressing, a key enabler of new high performance protocols. We then present ALBA-WUR, a cross-layer solution for data gathering in sensing systems that redesigns a previous leading protocol, ALBA-R, extending it to exploit the features of our WRx. We finally show results of the simulation-based performance evaluation of ALBA-WUR, quantifying the gain produced by the use of WRx with semantic addressing: Short delays, up to five orders of magnitude energy savings and lifetimes that are decades longer than those obtained by ALBA-R in sensing systems with duty cycling.

TITLE: « Scalable Multi-hop Wireless Networks »
ABSTRACT : Multi-hop wireless networks encompass a broad swathe of wireless networks in which a packet is relayed over multiple wireless hops before reaching the wired infrastructure or destination. Examples include (mobile) ad hoc networks, sensor networks and mesh networks. Scalable multi-hop wireless communications is viewed as a key requirement and enabler in emerging architectures such as the Internet of Things and 5G.
In this talk we begin by discussing the trends and applications of multi-hop wireless networks, and then focus on the problem of designing scalable multi-hop wireless networks. We contrast the well-known aysmptotic scalability with complementary work on "in practice" scalability -- in particular, a framework that allows us to roughly estimate the scalability of a real-world multi-hop wireless network. Insights from such analysis underscore the importance of not only network-layer, but also medium access, physical and cross-layer solutions, and motivate a radically new architecture for next generation multi-hop networks as the way forward. We conclude with a brief discussion of possible future research directions including in the intersection of multihop networking concepts with other fields such as social networks and algebraic topology.
