gt-mobisim Description

You can change the # of objects in the config file. However, the trace file is not overwritten/regenerated if it already exists. If you change the # of objects in the config file, but use a trace file that was generated with a different # of objects, some objects might not have traces, which can cause an exception. Main Features: - generate mobility traces for mobile objects moving in a road network - 100k objects, 10 minutes, flowing traffic speeds, velocity step-function representation, continuous time (no sampling) => ~235 MB trace - simulation driven by an xml configuration file - can be run as a text-mode only batch job (eg. on ssh-access-only Linux box) - simple GUI, when running on graphical terminal - vector map formats: - ESRI Shapefile (.shp), eg. U.S. Census Bureau, TIGER/Line Shapefiles - GlobalMapper-exported USGS data (.svg), - various mobility models on road networks - random waypoint - random trip - 3 ways to represent continuous-time traces - location step-function - velocity step-function - acceleration step-function - locations of mobile objects at any time instance (ie. continuous vs. sampled locations) - conversion from continuous-time traces to periodically sampled location traces - ability to specify various parameter distributions - Gaussian distribution with mean & standard deviation min & max cutoff - normal distribution with min & max - generate query traces - query creation - query deletion
