Introduction
The WISN Lab, led by Dr. Muhammad Shahzad, focuses on two broad research areas: ubiquitous sensing and networking. On the ubiquitous sensing side, we are currently focusing on leveraging ambient modalities, such as WiFi, RF, light, and sound, to perform a variety of ubiquitous sensing tasks, such as monitoring the activities of occupants in indoor environments, tracking the state of appliances in buildings, improving the accuracies of sensors on handheld devices and other projects along similar lines. On the networking side, we focus on a variety of measurement problems in wireless networks, data centers, public clouds, and RFID networks. Our network measurement work not only involves characterization of various aspects in these networks but also involves developing the techniques to obtain the measurements. WISN lab is supported by National Science Foundation, Army Research Office, Kenan Institute, Lab for Analytic Sciences, NCSU's Office of Research, Innovation, and Economic Development, Sony, Amazon, Google, and PLUMgrid (now acquired by VMWare).
