Simulator for generating mobility traces and query traces for large numbers of mobile agents moving in a road network.

How to get gt-mobisim, along with source code, sample simulation configs & maps?

• QuickStart

Example codes for using & extending the simulator

• ExampleCode

Demo

Playback of pre-generated simulation with this configuration xml.

Features

Does:

• 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 http://www.census.gov/geo/www/tiger/
• GlobalMapper-exported USGS data (.svg), see: http://edc2.usgs.gov/geodata/index.php
• 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

Doesn't do:

• execution of client-side codes (ie. code that runs on simulated mobile users' phones)
• have a simulated server, or have simulated client-server communication
