ns2 Aim: Support networking research and education For protocol design, traffic studies Free open source - on Linux, Windows and Mac Includes Wired networks Routing Distance Vector (DV), Link States (LS) Transportation: TCP and UDP Traffic: Ftp, Telnet, Cbr (Constant bit ratess) Queuing models: Drop-tail, RED QoS support frameworks: IntServ and Diffserv Wireless networks Ad hoc routing protocols (AODV, DSR) and mobile IP Directed diffusion, sensor-MAC Utilities for tracing and visualization Details:

Qualnet A good simulator for studying networks A commercial version - we have 5 licenses at DBH. Rapid prototyping of protocols with GUI tools and the modular, layered sta ck design Scalability via support for parallel execution Includes Many types of networks: Wired and wireless (WLANs, Cellular, Ad hoc) Various existing protocols (good for comparative performance evaluation) Easy for tracing and visualization. More scalable than ns2 (support thousands of nodes)

OverSim OverSim is a C++ based open-source overlay and peer-to-peer network simulation framework for the OMNet++ simulation environment. Built-in Modules : Structured (Chord, Pastry, Bamboo, Koorde, Broose, Kademlia), Unstructured (GIA) P2P and other Overlay Protocols (NICE, NTree, Quon, Vast, Publish-Subscribe for MMOGs) You can add a C++ module to run your own protocol on OverSim

PeerSim PeerSim is a Java-based peer-to-peer system simulator with two simulation engines (a cycle- based and an event driven). Built-in Modules: Pastry, Chord, Kademlia, Skpnet, Bittorrent, TMan, Cloudcast. You can build a java package of your own protocol to run on PeerSim.
