In , the authors evaluated the performance of Gnutella
using various flat underlying reactive and proactive routing protocols.
(8) "Governments are good at cutting off the heads of a centrally controlled network like Napster," Satoshi wrote, "but pure P2P networks like Gnutella
and Tor seem to be holding their own." Ibid.
One could also pick from any of a number of other P2P services such as Gnutella
, Kazaa, Scour, Grokster, etc.
In unstructured P2P networks, such as Gnutella
, the most common mechanism is flooding.
An example of such a network is Gnutella
which has no central server but clusters its nodes around so-called "supernodes".
Napster was quickly followed by other platforms such as Gnutella
, Grokster, Kazaa, and BitTorrent, as well as "pirate" resources such as The Pirate Bay and the dark web.
In this research work, we used a well know ad hoc routing protocol Ad hoc On Demand Distance Vector (AODV) under a peer-to-peer network protocol Gnutella
. A cross layer optimization has been made for these protocols to increase the energy efficiency.
A famous example is Gnutella
, a program with a Nutella-sounding name in honor of the passion for the product used to exchange files.
claimed that nearly 70% of Gnutella
users share no files .
Investigation shows that: a measurement study of the Gnutella
file sharing network  found that approximately 70% of peers provided no files and that approximately 37% of the total files are provided by the top 1% of the peers.
He answered his own question by developing a new p2p network called Gnutella
