The main contribution of this work is to decipher the power and energy characteristics of IEEE 802.11 PHY. In this work, we implement an IEEE 802.11n receiver and transmitter benc...
To reduce the amount of data transfer in networked control systems and wireless sensor networks, measurements are usually taken only when an event occurs, rather than at each synch...
Abstract—This paper proposes a low-complexity twodimensional channel estimator for MIMO-OFDM systems derived from a time-frequency variant channel estimator previously proposed. ...
The problem of node localization in a wireless sensor network (WSN) with the use of the incomplete and noisy distance measurements between nodes as well as anchor position informa...

In 2003, we presented an architecture for a streaming video quality assessment system [1]. Six years later, many of the challenges outlined in that paper remain. This paper revisit...
