ns-2 Trace Toolkit was developed to help users to manage and debug ns-2 trace files. It is particularly useful for users that generate ns-2 trace files with other tools such as VanetMobiSim or SUMO (Simulation of Urban Mobility).
With ns-2 Trace Toolkit, users can debug their trace files by generating histograms for: (1) node speed, (2) node x-position, and (3) node y-position. These histograms can give hits about
concentration of nodes.
