Low-power wireless communication is a central building block of cyber-physical systems
and the Internet of Things. Conventional low-power wireless protocols make avoiding packet …

We can often detect from a person's utterances whether he or she is in favor of or against a
given target entity—one's stance toward the target. However, a person may express the …

Time slotted operation is a well-proven approach to achieve highly reliable low-power
networking through scheduling and channel hopping. It is, however, difficult to apply time …

In this paper, we strive to construct an efficient multi-hop network based on the sub-GHz low-
power wide-area technology. Specifically, we investigate the combination of LoRa, a …

Constructive interference (CI) can happen when multiple wireless devices send the same
frame at the same time. If the time offset between the transmissions is less than 500 ns, a …

We present mLoRa in this paper, a novel protocol that can decode multiple collided packets
simultaneously from different transmitters in LoRa networks. As a recently proposed wireless …

An important building block for low-power wireless systems is to efficiently share and
process data among all devices in a network. However, current approaches typically split …

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 …

Cross-technology communication (CTC) is a technique that enables direct communication
among different wireless technologies. Recent works in this area have made substantial …

Data prediction in wireless sensor networks replaces the commonly used (periodic) data
reporting with a model, updated (infrequently) at the sink to accurately reproduce real data …
