Outage Duration in Poisson Networks and its Application to Erasure Codes
Udo Schilcher, Siddhartha Borkotoky, Jorge F. Schmidt +1
We derive the probability distribution of the link outage duration at a typical receiver in a wireless network with Poisson distributed interferers sending messages with slotted ra…
A Performance Evaluation Tool for Drone Communications in 4G Cellular Networks
Christian Raffelsberger, Raheeb Muzaffar, Christian Bettstetter
We introduce a measurement tool for the performance evaluation of wireless communications with drones over cellular networks. The Android software records various LTE parameters, e…
Cooperative Relaying in LoRa Sensor Networks
Siddhartha Borkotoky, Udo Schilcher, Christian Bettstetter
We propose a communication scheme with relays to improve the reliability of a Long Range (LoRa) sensor network with duty-cycle limitations. The relays overhear the sensors' transmi…
Allocation of Repetition Redundancy in LoRa
Siddhartha Borkotoky, Christian Bettstetter, Udo Schilcher +1
We consider a multipoint-to-point network in which sensors periodically send measurements to a gateway. The system uses Long Range (LoRa) communications in a frequency band with du…
A review of swarmalators and their potential in bio-inspired computing
Kevin O'Keeffe, Christian Bettstetter
From fireflies to heart cells, many systems in Nature show the remarkable ability to spontaneously fall into synchrony. By imitating Nature's success at self-synchronizing, scienti…
Interference Prediction in Wireless Networks: Stochastic Geometry meets Recursive Filtering
Jorge F. Schmidt, Udo Schilcher, Mahin K. Atiq +1
This article proposes and evaluates a technique to predict the level of interference in wireless networks. We design a recursive predictor that estimates future interference values…
