In previous work we have presented a prototype of an assistant system for the blind that can be used for self-localization and interactive object identification of static objects ...
In this paper, we define a model of an ad hoc routing protocol, i.e. the OLSR (Optimized Link-State Routing) protocol. This model handles novel constraints related to such networ...
Adding a sound information flow security policy to an existing program is a difficult task that requires major analysis of and changes to the program. In this paper we show how ...
We explore fundamental performance limits of tracking a target in a two-dimensional field of binary proximity sensors, and design algorithms that attain those limits. In particul...
Fast and effective distribution of software updates (a.k.a. patches) to millions of Internet users has evolved into a critical task over the last years. In this paper, we characte...
