Decoding Superposed LoRa Signals

Long-range low-power wireless communications, such as LoRa, are used in many IoT and environmental monitoring applications. They typically increase the communication range to several kilometers, at the cost of reducing the bitrate to a few bits per seconds. Collisions further reduce the performance of these communications. In this paper, we propose two algorithms to decode colliding signals: on...

Profile of Lora V. Hooper.

Lora Hooper, a professor of immunology at the University of Texas Southwestern Medical Center, describes her career as “a random walk in science.” Her pursuit of science was aided by inspirational mentors who pointed her in directions she might not otherwise have taken. These unexpected turns ultimately led her to study the microbiome: the community of microorganisms that reside in and on multi...

LORA: Link Obfuscation by Randomization in Graphs

In this paper, we propose a randomization scheme, LORA (Link Obfuscation by Randomization), to obfuscate edge existence in graphs. Specifically, we extract the source graph’s hierarchical random graph model and reconstruct the released graph randomly with this model. We show that the released graph can preserve critical graph statistical properties even after a large number of edges have been r...

LoRa for the Internet of Things

New transceiver technologies have emerged which enable power efficient communication over very long distances. Examples of such Low-Power Wide-Area Network (LPWAN) technologies are LoRa, Sigfox and Weightless. A typical application scenario for these technologies is city wide meter reading collection where devices send readings at very low frequency over a long distance to a data concentrator (...
