Publish-Subscribe Systems via Gossip: a Study based on Complex Networks
Stefano Ferretti
This paper analyzes the adoption of unstructured P2P overlay networks to build publish-subscribe systems. We consider a very simple distributed communication protocol, based on gos…
Mitigation of Random Query String DoS via Gossip
Stefano Ferretti, Vittorio Ghini
This paper presents a mitigation scheme to cope with the random query string Denial of Service (DoS) attack, which is based on a vulnerability of current Content Delivery Networks…
Auction-Based Resource Allocation in Digital Ecosystems
Moreno Marzolla, Stefano Ferretti, Gabriele D'Angelo
The proliferation of portable devices (PDAs, smartphones, digital multimedia players, and so forth) allows mobile users to carry around a pool of computing, storage and communicati…
Scale-Free Opportunistic Networks: is it Possible?
Stefano Ferretti, Vittorio Ghini
The coupling of scale-free networks with mobile unstructured networks is certainly unusual. In mobile networks, connections active at a given instant are constrained by the geograp…
Mobile Computing in Digital Ecosystems: Design Issues and Challenges
Gabriele D'Angelo, Stefano Ferretti, Vittorio Ghini +1
In this paper we argue that the set of wireless, mobile devices (e.g., portable telephones, tablet PCs, GPS navigators, media players) commonly used by human users enables the cons…
LUNES: Agent-based Simulation of P2P Systems (Extended Version)
Gabriele D'Angelo, Stefano Ferretti
We present LUNES, an agent-based Large Unstructured NEtwork Simulator, which allows to simulate complex networks composed of a high number of nodes. LUNES is modular, since it spli…
