Wireless and Sensor Network Research Group - WiSeNet Lab

Group Overview

The WiSeNet lab at NCSU consists of graduate students and faculty at North Carolina State University conducting research on wireless mesh networks, cellular multicast scheduling and topology control/energy efficiency in sensor networks. We have a wireless testbed comprising of 120 MicaZ sensor nodes and 60 802.11x-based Soekris nodes.
