This poster describes a low-cost and robust embedded platform, designed for vehicle mounted sensing of particulate matter (PM2.5 and PM10). The prototype is specifically designed to be mounted on the Delhi Integrated Multi-Modal Transit System (DIMTS) ...

Motivated by applications like Information Centric Networking for the Internet of Things, we study caching policies for the setting where the data being cached is heterogeneous in nature. This heterogeneity is in two aspects, namely, the lifetime of the ...

We consider a system consisting of multiple sensors, a central monitoring station, and multiple orthogonal frequency channels. The sensors measure heterogeneous time-varying signals and report their measurements to the central monitoring station which ...

In addition to reducing the environmental footprint, smart energy monitoring systems today should reduce operating costs, provide insights on energy consumption, and manage load distribution. This involves monitoring the overall energy consumption of a ...

Infusion monitoring is in great demand for the hospital. In this demo, we propose RF-iCare, an RFID-based approach for monitoring the infusion status, including the liquid level and the drop speed. With a tag array attached on the infusion bottle, we ...

This paper presents a battery-free wearable eye tracker that tracks both the 2D position and diameter of a pupil based on its light absorption property. With a few near-infrared (NIR) lights and photodiodes around the eye, NIR lights sequentially ...

Passive radio frequency identification (RFID) tags are ubiquitous today due to their low cost (a few cents), relatively long communication range ($\sim$7-11~m), ease of deployment, lack of battery, and small form factor. Hence, they are an attractive ...
