Downlink beamforming algorithms with inter-cell interference in cellular networks
— We study the issue of handling unknown inter-cell interference in multi-cell environments with antenna arrays at the base stations. First, we demonstrate that the presence of u...

Sharing Random Bits with No Process Coordination
We present a method by which any polynomial-time randomized distributed algorithm is transformed in such way that each participating process needs only polylog local random bits a...

Transparent Distributed Threads for Java
Remote method invocation in Java RMI allows the flow of control to pass across local Java threads and thereby span multiple virtual machines. However, the resulting distributed t...

Differentially private aggregation of distributed time-series with transformation and encryption
We propose PASTE, the first differentially private aggregation algorithms for distributed time-series data that offer good practical utility without any trusted server. PASTE add...

Computing best-possible bounds for the distribution of a sum of several variables is NP-hard
In many real-life situations, we know the probability distribution of two random variables x1 and x2, but we have no information about the correlation between x1 and x2; what are ...
