Spam filter developers are confronted with the task of integrating their ideas in user-friendly products. In this paper, we introduce Spamato as an open, extendable, and multi-faceted spam filter framework. Spamato provides fundamental services commonly required by filter developers to facilitate the implementation of new approaches. Furthermore, we support email clients with add-ons to enable users to intuitively collaborate with Spamato. We also present a variety of filters and exhibit an evaluation of URL-based techniques.
This paper presents Glossy, a novel flooding architecture for wireless sensor networks. Glossy exploits constructive interference of IEEE 802.15.4 symbols for fast network flooding and implicit time synchronization. W...

We present a new technique called "Three Plane Localization" to improve the accuracy of many existing range based and range free localization schemes. The key idea is to intentionally create interference at ...
Collecting highly accurate scientific measurements asks for highest data quality and yield. But, satisfying these requirements is non-trivial, when considering phenomena common to wireless sensing systems such as cloc...
