Scalable Network Tomography for Dynamic Spectrum Access

NeTo-X is a scalable network tomography framework that maps interference patterns and estimates joint client access statistics with only linear overhead—paving the way for more efficient dynamic spectrum access in future networks. By exploiting multi-channel diversity and the spatial locality of interference, NeTo-X accurately infers...

Renting Edge Computing Resources for Service Hosting

This paper is about Better-Late-Than-Never (BLTN), an online algorithm which decides the state of an edge computing server based on historic request arrival rates. In this work, we propose a deterministic online policy and characterize its performance for adversarial and stochastic request arrival processes. We...

Low-power backscatter sensing prototype

Research project

Backscatter for Low-power IoT Environmental Sensing

In this project, we built an ultra-low power backscatter device for monitoring Atlanta’s urban heat islands, using digital communications techniques to extend the range between the tag and transmitter/receiver by sacrificing throughput. We explore digital range-increasing techniques such as forward error correction (FEC) and investigate...
