The PAF-FPE Project

This is the website of the PAF-FPE project. A Marie-Curie project run by Leonardo Maccari in the period 2011-2014. I do not plan to update this website anymore, If you are interested in this project, you can find a description and a list of achievements in this short Executive Summary. In that pdf I will also update the publication list as the last papers get published.


Publications and advances

Two new papers have been published as a result for the Pervacy project. The first one is a follow-up of the paper presented to WONS 2012 that have been accepted to Secrypt 2012. The title is A collaborative firewall for wireless ad-hoc social networks, starting from the work on WONS  I have measured the impact of large rule-sets in real devices in terms of forwarding delay and I added more results on the firewalling based on the Selector set size for OLSR networks.


My big disillusionment with Wordpress

This blog is "powered by wordpress", not so proudly anymore. It is hosted on a Debian machine and uses the (quite old) Debian package just because I don't want to keep track of updates and I let the folks from Debian do that job for me. Nevertheless few months ago I've found in the the blog links to spamming websites. This happened because in June some vulnerabilities have been found in the WP source code. Ok, this can happen, what is the correct procedure to handle it?


Bug in MPR Selection, Omnet++, NS2, NS3

I'm now working on the integration of filtering strategies with the OLSR protocol, in order to exploit the knowledge of the topology to have more efficient filtering. Doing this, I had the intuition on some improvement on the choice of MPR nodes, but while working on it, I found a couple of bugs on the OLSR implementation of MPR selection in Omnet++ implementation, in NS2 and partly in NS3. I have reported the bug in the Omnet mailing list and it has been fixed, I will explain it also here so that other people that are using this code can be correct it (also in the NS3 community).


See you at the Amsterdam Privacy Conference

A paper I wrote entitled On privacy implications of distributed wireless social networks has been accepted at the Amsterdam Privacy Conference to be held in October. I've very excited to go there since the group that is organising the event has an approach I really like, mixing scientists coming from different fields, from computer science to social sciences. Moreover the keynotes are, among others, Helen Nissenbaum and Alessandro Acquisti, that I cite quite a lot!



WONS workshop

While still developing code to have big simulations, we have the first results. Here you can find the paper and if you click on the image below you can read the poster presented at the WONS workshop in Jan 2012.

Co-located with WONS we had the Italian networking workshop where I presented an extended version of the paper, it is a tech report we are finalizing, you can find a preprint here.


Omnet++ radio range, pathloss and error model

I've had some hard time in figuring out how omnet++ handles the propagation of radio signals, so thought I'll write it here to remind it to myself and others in the future.

These are standard value for radio parameters:
**.wlan[*].radio.sensitivity = -85dBm
**.wlan[*].radio.snirThreshold = 4dB


Chat application for Omnet++

This commit adds a model for a Chat application to Inet. Chat is one of the most used application type in social networks so I needed a realistic model to describe the statistical features of this kind of traffic.


AddressGenerator for Inet

In the this commit I've added a new module that is quite useful in Inet simulations. It is an address generator that the applications can use to choose the destination of the sessions they open. The need for this is that each application takes care of choosing where to send the next packet, but it does this quite simply, whether you specify it on configuration or, some, take a random() keyword meaning anyone.


ICC source code

I'm still working on the publication of code to re-create the simulations as submitted to ICC. The code is still not really presentable, if you're interested in the code used for ICC (maybe you're a revisor? ;-) ) email me and I'll send an "as-is" tar.gz
