Model Current Status and Limitations Future Trends
ns2 • The simulated environment is
assumed to be a flat empty area
in which mobile nodes move
without interference in their
signals
• The distance between wireless
devices affects the signal level
and transmission speeds
drastically
• It is hard to simulate proximity
and environmental noise-related
simulations
• Limited nearly 500 nodes
• It is hard to develop new protocol
• Debugging and output tracing is
not straightforward
ns2 is the most popular network
simulator in the network ...
