An analytical approach to real-time misbehavior detection in IEEE 802.11 based wireless networks
—The distributed nature of the CSMA/CA based wireless protocols, e.g., the IEEE 802.11 distributed coordinated function (DCF), allows malicious nodes to deliberately manipulate t...

Observe Locally, Infer Globally: a Space-Time MRF for Detecting Abnormal Activities with Incremental Updates
We propose a space-time Markov Random Field (MRF) model to detect abnormal activities in video. The nodes in the MRF graph correspond to a grid of local regions in the video fra...

Impact of NVRAM write cache for file system metadata on I/O performance in embedded systems
File systems make use of part of DRAM as the buffer cache to enhance its performance in traditional systems. In this paper, we consider the use of Non-Volatile RAM (NVRAM) as a w...
