Advances in mobile (cellular) networks have ushered in an era of abundant connectivity. However, the stationary and expensive nature of their deployment has limited their ability to provide true "ubiquitous" connectivity under the 5G vision - especially ...

We provide the first solution to an important question, "how a physical-layer RFID authentication method can defend against signal replay attacks". It was believed that if the attacker has a device that can replay the exact same reply signal of a ...

Frame aggregation in 802.11n and ac gives higher throughputs because larger aggregates reduce inter-frame timing overheads. When aggregate (A-MPDU) sizes are forced to be smaller the throughput benefit dwindles. During normal operation the A-MPDU sizes ...

With the exponential increase in number of connected sensor devices for various smart home applications, a huge amount of heterogeneous data are generated every day. Collection technique plays a crucial role in defining the application QoS. In this ...

Today, experiencing virtual reality (VR) is a cumbersome experience which either requires dedicated infrastructure like infrared cameras to track the headset and hand-motion controllers (e.g. Oculus Rift, HTC Vive), or provides only 3-DoF (Degrees of ...

There is growing interest in the research community to develop techniques for humans to communicate with the computing that is embedding into our environments. Researchers are exploring various modalities, such as radio-frequency signals, to develop ...

Wireless communication in mmWave bands with wide bandwidths and directional links is crucial for high data rate demands of future networks. A key challenge in mmWave networking is maintaining beam alignment under device mobility such as rotation or ...

We propose the design of a battery-free wearable eye tracker that achieves sub-millimeter tracking accuracy at high tracking rates. It tracks pupil's 2D position based on pupil's light absorption effect. With a few near-infrared (NIR) lights and ...

The emergence of mobile mixed reality (MR) and augmented reality (AR) frameworks portends a future of computational immersion, placing virtual objects amidst physical environments. As MR and AR become increasingly accessible and programmable, immersive ...
