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…
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…
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…
On the Degree Distribution of Faulty Peer-to-Peer Overlays
Stefano Ferretti
This paper presents an analytical framework to model fault-tolerance in unstructured peer-to-peer overlays, represented as complex networks. We define a distributed protocol peers…
