WiFiEye -- Seeing over WiFi Made Accessible
Philipp H. Kindt, Cristian Turetta, Florenc Demrozi +3
While commonly used for communication purposes, an increasing number of recent studies consider WiFi for sensing. In particular, wireless signals are altered (e.g., reflected and a…
Performance Limits of Neighbor Discovery in Wireless Networks
Philipp H. Kindt, Samarjit Chakraborty
Neighbor Discovery (ND) is the process employed by two wireless devices to discover each other. There are many different ND protocols, both in the scientific literature and also th…
Optimizing BLE-Like Neighbor Discovery
Philipp H. Kindt, Swaminathan Narayanaswamy, Marco Saur +1
Neighbor discovery (ND) protocols are used for establishing a first contact between multiple wireless devices. The energy consumption and discovery latency of this procedure are de…
Identifying the BLE Advertising Channel for Reliable Distance Estimation on Smartphones
Christian Gentner, Daniel Günther, Philipp H. Kindt
As a response to the global COVID-19 surge in 2020, many countries have implemented lockdown or stay-at-home policies. If, however, the contact persons of every infected patient co…
How Reliable is Smartphone-based Electronic Contact Tracing for COVID-19?
Philipp H. Kindt, Trinad Chakraborty, Samarjit Chakraborty
Smartphone-based electronic contact tracing is currently considered an essential tool towards easing lockdowns, curfews, and shelter-in-place orders issued by most governments arou…
On Optimal Neighbor Discovery
Philipp H. Kindt, Samarjit Chakraborty
Mobile devices apply neighbor discovery (ND) protocols to wirelessly initiate a first contact within the shortest possible amount of time and with minimal energy consumption. For t…
Fast Collision Simulation for Cyclic Wireless Protocols
Philipp H. Kindt, Sangyoung Park, Samarjit Chakraborty
With most modern smartphones supporting wireless protocols such as Bluetooth Low Energy (BLE) or ANT+, the number of networks are growing rapidly. Therefore, collisions among multi…
Slotless Protocols for Fast and Energy-Efficient Neighbor Discovery
Philipp H. Kindt, Marco Saur, Samarjit Chakraborty
In mobile ad-hoc networks, neighbor discovery protocols are used to find surrounding devices and to establish a first contact between them. Since the clocks of the devices are not…
Neighbor discovery latency in BLE-like duty-cycled protocols
Philipp Kindt, Marco Saur, Michael Balszun +1
Neighbor discovery is the procedure using which two wireless devices initiate a first contact. In low power ad-hoc networks, radios are duty-cycled and the latency until a packet m…
Precise Energy Modeling for the Bluetooth Low Energy Protocol
Philipp Kindt, Daniel Yunge, Robert Diemer +1
Bluetooth Low Energy (BLE) is a wireless protocol well suited for ultra-low-power sensors running on small batteries. BLE is described as a new protocol in the official Bluetooth 4…
