ChiangMobility

Package: inet.mobility.single

ChiangMobility

simple module

Uses a probabilistic transition matrix to change the state of motion. In this model, the state of the mobile node in each direction (x and y) can be:

  • the node stays in its current position
  • the node moves forward
  • the node moves backward
