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?

Example codes for using & extending the simulator

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:
  • 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
