On the Statistics and MAC Implications of Channel Estimation Errors in MIMO Ad Hoc Networks
—In this paper, we propose an analytical technique to evaluate the statistics of the channel estimation error in a simple multi-user ad hoc networking scenario. This problem is v...

Localized Access Point Association in Wireless LANs with Bounded Approximation Ratio
— The current access point (AP) association schemes in wireless LANs, such as IEEE 802.11, cause an unbalanced load which reduces the performance of both the entire network and i...

A Taxonomy of Botnet Structures
We propose a taxonomy of botnet structures, based on their utility to the botmaster. We propose key metrics to measure their utility for various activities (e.g., spam, ddos). Usi...
