Extends

Name Type Description
MobilityBase simple module

Abstract base module for mobility models.

Known subclasses

Name Type Description
AnsimMobility simple module

Uses the <position_change> elements of the ANSim tool's trace file.

BonnMotionMobility simple module

Uses the native file format of BonnMotion (http://www.cs.uni-bonn.de/IV/BonnMotion/).

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:

CircleMobility simple module

Moves the node around a circle.

GaussMarkovMobility simple module

Uses a Gauss-Markov model to control the randomness in the movement. Totally random walk (Brownian motion) is obtained by setting alpha=0, while alpha=1 results a linear motion.

LinearMobility simple module

This is a linear mobility model with speed, angle and acceleration parameters. Angle only changes when the mobile node hits a wall: then it reflects off the wall at the same angle.

MassMobility simple module

This is a random mobility model for a mobile host with a mass. It is the one used in "Optimized Smooth Handoffs in Mobile IP" by Perkins &Wang.

MoBanCoordinator simple module

This is the coordinator module of the MoBAN mobility model. It should be instantiated in the top level simulation network in MiXiM, once per WBAN. The coordinator module is the main module that provides the group mobility and correlation between nodes in a WBAN. In the initialization phase, it reads three user defined input files which are the postures specification file, a configuration file which includes all required parameter for specific distributions, and the previously logged mobility pattern, if it is requested to use a logged pattern. Note that all WBAN instances may use the same input files if they are exactly in the same situation.

MoBanLocal simple module

This is the local mobility module of MoBAN. It should be instantiated in each node that belongs to a WBAN. The NED parameter "coordinatorIndex" determine to which WBAN (MoBanCoordinator) it belongs. The current implementation uses the Random Walk Mobility Model (RWMM) for individual (local) movement with a sphere around the node, with given speed and sphere radius of the current posture. The reference point of the node it the current posture, the sphere radius, and the speed is given by the corresponding coordinator. RWMM determines the location of node at ant time relative to the given reference point.

Ns2MotionMobility simple module

TODO: why does this comment refer to BonnMotion instead of NS2?

RandomWaypointMobility simple module

Implements the Random Waypoint mobility model.

RectangleMobility simple module

Moves the node around a rectangle.

TractorMobility simple module

Moves a tractor through a field with a certain amount of rows. Since the tractor also moves around the field, the tractor travels the number of rows PLUS one rows. Consider the following piece of ascii-art for rows=2.

TurtleMobility simple module

A LOGO-style movement model, with the script coming from XML. It can be useful for describing random as well as deterministic scenarios.
