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. In that paper I mentioned a counter-intuitive result, that is, if in OLSR you set the willingness of a few nodes to WILL_ALWAYS you expect that the total number of MPRs in the network will increase, but simulations show the opposite. Investigating this issue we had the idea that led to the second paper How to Reduce and Stabilize MPR sets in OLSR networks that was accepted and is going to be presented to WiMob 2012 by Renato. During this work I found the bugs reported in a previous post in the NS2/NS3/Omnet++ simulator code for OLSR. Interestingly enough I found some papers in literature that used that code, even to evaluate the behaviour of the bugged MPR choice function. Hopefully the authors did spot the bugs and corrected them without mentioning.
The interaction between privacy policies and routing is a crucial item for multi-hop wireless networks both under the point of view of filtering, that was the main focus of your first works, but also under other points of view, such as the ones explored by Juan Li. We are still finalizing works on the first approach, but I'm willing to explore this interesting direction.
