This paper explores if wireless cut-through is possible. Unlike wired cut-through, wireless cut-through, if realized, can reduce latency and improve throughput by upto 3x. This paper shows that one way to implement cut-through is for every node to ...

This paper revisits the randomized backoff problem in CSMA networks and identifies opportunities of improvement. The key observation is that today's backoff operation, such as in WiFi, attempts to create a total ordering among all nodes contending for ...

One of the central challenges in backscatter is how to enable concurrent transmissions. Most backscatter protocols operate in a sequential TDMA-like manner due to the fact that most nodes cannot overhear each other's transmissions, which is detrimental ...

We introduce Harmonia, a new RF-based localization scheme that provides the simplicity, cost, and power advantages of traditional narrowband radios with the decimeter-scale accuracy of ultra wideband localization techniques. Harmonia is an asymmetric ...

We are facing an increasingly difficult challenge in spectrum management: how to perform real-time spectrum monitoring with strong coverage of deployed regions. Today's spectrum measurements are carried out by government employees driving around with ...

Heterogeneity in the wireless spectrum is an increasing problem which breaks down coordination and exacerbates wireless interference. In particular, this is a growing problem in the home: heterogeneity is increasing, yet there is a lack of tools and ...

Existing secret key extraction techniques use quantization to map wireless channel amplitudes to secret bits. This paper shows that such techniques are highly prone to environment and local noise effects: They have very high mismatch rates between the ...

Indoor localization of mobile devices and tags has received much attention recently, with encouraging fine-grained localization results available with enough line-of-sight coverage and enough hardware infrastructure. Synchronicity is a location system ...

Recent WiFi standards use Channel State Information (CSI) feedback for better MIMO and rate adaptation. CSI provides detailed information about current channel conditions for different subcarriers and spatial streams. In this paper, we show that CSI ...

We propose for the first time an integrated Visible Light Communication (iVLC) system, which combines scalable VLC networking and accurate VLC sensing of mobile users. To meet this goal, we envision using modulated LED lights for communications between ...
