PeerSim vs NeuroGrid: Protocols

PeerSim has a collection of internally developed protocols for the BISON project which can model P2P networks. They are the following:

• OverStat is a collection of aggregation protocols. Aggregation is a collective term for a set of functions aimed at providing statistical information over distributed systems, such as the average load of the nodes or the size of the network.
• SG-1 is a protocol for self-organizing and maintaining a superpeer based topology.
• The Peer sampling service, that can be used as a source of random peers by participating peers.
• The T-Man protocol can be used to build a wide range of different topologies using only a ranking function that defines the preference of each node for neighbors.
• The PdProtocol plays the Prisoner Dilemma between nodes in a network to achieve cooperation. It is based on a socially inspired mechanism (based on "tags") applied to P2P networks.
• The SLACER protocol generates a cooperative artificial social network (ASN) in a P2P overlay.

On the other hand, the NeuroGrid simulator supports the following protocols according to its FAQs:

• Gnutella
• Freenet
• NeuroGrid
• Pastry
• Chord
