Application-Layer Coding with Intermittent Feedback under Delay and Duty-Cycle Constraints
Siddhartha S. Borkotoky, Udo Schilcher, Christian Raffelsberger
We propose two application-layer coding schemes for delay-constrained point-to-point packet communications with restrictions on the transmitter's maximum duty-cycle. The schemes op…
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…
Packet Travel Times in Wireless Relay Chains under Spatially and Temporally Dependent Interference
Alessandro Crismani, Udo Schilcher, Stavros Toumpis +2
We investigate the statistics of the number of time slots that it takes a packet to travel through a chain of wireless relays. Derivations are performed assuming an interferenc…
