A Safe Reinforcement Learning Architecture for Antenna Tilt Optimisation

Erik Aumayr, Saman Feghhi, Filippo Vannella +2

Safe interaction with the environment is one of the most challenging aspects of Reinforcement Learning (RL) when applied to real-world problems. This is particularly important when…

Remote Electrical Tilt Optimization via Safe Reinforcement Learning

Filippo Vannella, Grigorios Iakovidis, Ezeddin Al Hakim +2

Remote Electrical Tilt (RET) optimization is an efficient method for adjusting the vertical tilt angle of Base Stations (BSs) antennas in order to optimize Key Performance Indicato…

An Efficient Web Traffic Defence Against Timing-Analysis Attacks

Saman Feghhi, Douglas J. Leith

We introduce a new class of lower overhead tunnel that is resistant to traffic analysis. The tunnel opportunistically reduces the number of dummy packets transmitted during busy ti…

Proportional Fair Rate Allocation for Private Shared Networks

Saman Feghhi, Douglas J. Leith, Mohammad Karzand

In this paper, we consider fair privacy in a shared network subject to traffic analysis attacks by an eavesdropper. We initiate the study of the joint trade-off between privacy, th…

A Web Traffic Analysis Attack Using Only Timing Information

Saman Feghhi, Douglas J. Leith

We introduce an attack against encrypted web traffic that makes use only of packet timing information on the uplink. This attack is therefore impervious to existing packet padding…
