Accelerating Update Broadcasts Over LoRaWAN Downlink via D2D Cooperation
Anshika Singh, Siddhartha S. Borkotoky
Broadcast distribution of updates (e.g., security patches, machine learning models) from a server to end devices (EDs) is a critical requirement in the Internet of Things (IoT). In…
Balancing the Energy Consumption and Latency of Over-the-Air Firmware Updates in LoRaWAN
Siddhartha S. Borkotoky
Over-the-air firmware updates are crucial for mitigating security threats and maintaining up-to-date device functionality in Long Range Wide Area Networks (LoRaWANs). LoRaWAN end d…
Federated Learning Over LoRa Networks: Simulator Design and Performance Evaluation
Anshika Singh, Siddhartha S. Borkotoky
Federated learning (FL) over long-range (LoRa) low-power wide area networks faces unique challenges due to limited bandwidth, interference, and strict duty-cycle constraints. We de…
Message Replication for Improving Reliability of LR-FHSS Direct-to-Satellite IoT
Sonu Rathi, Siddhartha S. Borkotoky
Long-range frequency-hopping spread spectrum (LR-FHSS) promises to enhance network capacity by integrating frequency hopping into existing Long Range Wide Area Networks (LoRaWANs).…
Time-Constrained Erasure Correction for Data Recovery in UAV-Aided IoT
Kushwanth Sistu, Siddhartha S. Borkotoky
We propose data-recovery schemes to improve the uplink reliability of Internet of Things (IoT) networks in which a gateway mounted on an unmanned aerial vehicle (UAV) collects data…
Leveraging Wake-Up Radios in UAV-Aided LoRa Networks: Some Preliminary Results on a Random-Access Scheme
Shashank M. S. Panga, Siddhartha S. Borkotoky
We present a transmission scheme aimed at integrating wake-up radios (WuR) into LoRa sensor networks featuring UAV-mounted gateways. The sensors are informed of the UAV's arrival w…
Making the Most of Sporadic Feedback: Low-Complexity Application-Layer Coding for Data Recovery in the Internet of Things
Vatsalya Chaubey, Siddhartha S. Borkotoky
We propose application-layer coding schemes to recover lost data in delay-sensitive uplink (sensor-to-gateway) communications in the Internet of Things. Built on an approach that c…
Coded Relaying in LoRa Sensor Networks
Siddhartha S. Borkotoky, Pavan Datta Abbineni, Vatsalya Chaubey +1
To enhance the reliability of LoRa sensor networks, we propose two opportunistic forwarding protocols in which relays overhear sensor-to-gateway messages and periodically forward t…
The LoRa Modulation Over Rapidly-Varying Channels: Are the Higher Spreading Factors Necessarily More Robust?
Harishwar Reddy Bapathu, Siddhartha S. Borkotoky
The chirp spread spectrum (CSS) modulation scheme is employed by the physical layer of the Long Range (LoRa) communication technology. In this paper, we examine the performance of…
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…
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…
