Filip Plata

Philipp Sommer, Jiajun Liu, Kun Zhao, Branislav Kusy, Raja Jurdak, Adam McKeown, David Westcott: “Information Bang for the Energy Buck: Towards Energy- and Mobility-Aware Tracking”, EWSN ‘16

Cheaper and more precise GPS mobility tracking — we will look at issues present in energy constrained environments, and how to work around them with the software. We will see it is possible to obtain substantial gains by carefully adapting the software.

30.10

Tomasz Kanas

Bassam J. Mohd, Thaier Hayajneh: “Lightweight Block Ciphers for IoT: Energy Optimization and Survivability Techniques”, IEEE Access, vol. 6, 2018

I will introduce a simple model for lightweight cipher performance metrics. Using this model we will explore the opportunities to improve performance and optimize energy consumption for ciphers designs targeted for low-resource IoT devices.

06.11

Hubert Pełczyński

Manuel Eichelberger, Kevin Luchsinger, Simon Tanner, Roger Wattenhofer: “Indoor Localization with Aircraft Signals”, SenSys ‘17

GPS is globally available, relatively accurate and receivers are inexpensive but it has one major drawback: very weak signal make it impossible to track a device indoors. We’ll explore a new localization approach, which uses the same principle as GPS localization, but employs signals transmitted by aircrafts.

Adam Wiktor

Yang Li, Rui Tan, David K. Y. Yau: “Natural Timestamping Using Powerline Electromagnetic Radiation”, IPSN ‘17

Having common notion of time among multiple wireless devices spread kilometers apart across a city usually requires expensive hardware or sophisticated synchronizing algorithms. However, we will show that it can be achieved much simpler, using powerline radiation.

13.11

Kamil Mykitiuk

Colleen Josephson, Lei Yang, Pengyu Zhang, Sachin Katti: “BackCam: Wireless Computer Vision Using Commodity Radios”, IPSN ‘19

I will introduce realtime computer vision system based on camera sensor and backscatter, full-duplex WiFi radio powered by two AA batteries. It is capable of transmitting images for over one month thanks to used image compression algorithms and dynamic configuration.

20.11

Jakub Wróblewski

Chulhong Min, Alessandro Montanari, Akhil Mathur, Fahim Kawsar: “A Closer Look at Quality-Aware Runtime Assessment of Sensing Models in Multi-Device Environments”, SenSys ‘19

Multiple sensors working in close vicinity can often have overlapping results of varying quality. Being able to assess this quality at execution time would allow us to save resources while simultaneously improve accuracy of sensor readings. During my presentation I will be talking about recently developed techniques for the runtime quality assessment.

27.11

Jakub Obuchowski

Rishi Shukla, Neev Kira, Jeremy Gummeson, Rui Wang, Sunghoon Ivan Lee: “SkinnyPower: Enabling Battery-less Wearable Sensors via Intra-Body Power Transfer”, SenSys ‘19

I will be talking about the concept of wireless, bateryless wearable devices. The main technological innovation is to utilize the human body as the medium to transfer power from a source to a wearable device. This idea eliminates the need of having bulky batteries on each wearable device and instead it allows to have only one source of power which reduces the maintenance task (e. g. recharching or replacement).

Karol Pieniący

How autonomous drone racing is influencing airborne distributed systems.

Drone racing might seem like a great show to the public and a lot of fun for the participants. I will advocate that our results influence different kinds of distributed systems in robotics. I will try to show benefits we can get from such challenge, especially focusing state of the art algorithms for airborne platforms.

22.01

Jaromir Górski

Kevin Kiningham, Mark Horowitz, Philip Levis, Dan Boneh: “CESEL: Securing a Mote for 20 Years”, EWSN ‘16

Due to the deployment of sensor networks and small IoT devices in critical infrastructures, security is becoming a big concern for such appliances. Additionally, they shouldn’t only be designed to be secure now, but also in the future. In this presentation, we will look into the reasons why security is problematic for low-power devices, what constitutes a secure embedded system, and we will examine a solution brought up in the paper: CESEL, a hardware-accelerated framework which provides essential security primitives for embedded systems at a low cost.
