RSSI is known to be a fickle indicator of whether a wireless link will work, for many reasons.
This greatly complicates operation because it requires testing and adaptation to find the best …

A wireless transmitter learns of a packet loss, infers collision, only after completing the entire
transmission. If the transmitter could detect the collision early (such as with CSMA/CD in …

Spinal codes are a new class of rateless codes that enable wireless networks to cope with
time-varying channel conditions in a natural way, without requiring any explicit bit rate …

Conventional WiFi networks perform channel contention in time domain. This is known to be
wasteful because the channel is forced to remain idle while all contending nodes are …

This paper presents the design, implementation and evaluation of Strider, a system that
automatically achieves almost the optimal rate adaptation without incurring any overhead …

We present results validating a novel framework for collecting and analyzing facial
responses to media content over the Internet. This system allowed 3,268 trackable face …

A fundamental problem in wireless networks is to develop communication protocols that
achieve high throughput in the face of noise, interference, and fading, all of which vary with …

Successive interference cancellation (SIC) is a physical layer capability that allows a
receiver to decode packets that arrive simultaneously. While the technique is well known in …

Backscatter communication offers an ultra-low power alternative to active radios in urban
sensing deployments-communication is powered by a reader, thereby making it virtually" …

A smart city involves big data transmission (BDT) between smart systems, which increases
queue delays and leads to difficulty in enhancing the spectral efficiency. Adaptive …
