MobiSim Changelog

What's new in MobiSim 3

Jul 15, 2013
  • New GUI that simplifies user interaction
  • Tortoise model: A very general transitional model, where you program nodes through sequence and loops of transitions. The parameters for transitions (direction, speed, duration, pausetime) can be randomized using many random distributions.
  • Location initializer: Ability to use various random and deterministic algorithms to set initial positions of nodes
  • Add obstacles to maps: Currently supports rectangular obstacles but you can scale and rotate them.
  • Range algorithms: Now you can set ranges of communication during simulation
  • Improve trace visulazation: Zoom and Pan maps, new visualization methods and integrated codes.
  • New Evaluators
  • Recognize transition and evaluate: Transition length, Transition time, Transition direction change, Transition speed
  • intermeeting time
  • Fix bugs
  • Cleaned code

New in MobiSim 2 (Jul 15, 2013)

  • Additional Models:
  • Levy walk
  • Model composer: This is a model which acts as a composer of multiple models. Its use cases contains:
  • an emergency help group finding for injured people. While the injured people have a low speed model, the emergency group runs faster
  • a battle field containing two groups some on the backup line and some on frontier behaving differently
  • a battle field containing two groups with a line between them where they seldom pass over it
  • 3D simulation:
  • ability to define a 3D map describing the height of each point
  • ability to run available models in a 3D environment with the defined map
  • 3d representation for simulated scenarios
  • Graphical map designer:
  • A graphical UI to configure maps
  • Additional trace formats: NS2 format
  • New evaluators:
  • Clustering Coefficient
  • Interference
  • Location Distribution Variance
  • Neighborhood instability (Topology Change Rate)
  • Network Diameter
  • Repetitive Behavior
  • Sort algorithm for evaluators
  • Evaluation analyzer is more powerful:
  • more classification algorithms added
  • Fuzzy KNN Classification
  • Fuzzy Guassian KNN Classification (3 versions)
  • Nearest Distance
  • Group SVD
  • Nearest Distance (SVD)
  • a module for evaluating classification algorithms and feature ranking implemented
  • calculate the degree of membership of a trace to each model
  • calculate accuracy of each classification algorithms
  • Documentation:
  • A developer guide for extending MobiSim is added
  • Fixed Bugs:
  • FreeWay map enhancement
  • Manhattan map input data error fixed
  • Model initialization exception handling
  • UI change to have the setup button and start/pause command on hand
  • Models should be able to add columns in the trace files
  • More detailed installation documentation
