Detailed Description

Class to provide spatial and temporal correlation in the posture selection process of the MoBAN mobility model.

This class obtains and stores Markovian transition matrices. There is also the possibility to get a steady state vector. In this case, the closest transition matrix to the default Makov matrix is extracted which satisfies the given steady state vector. The class also receives the defined area types and time domains as well as given space-time domains during the initialization phase. During the simulation run, the class provide a functions to return the corresponding markov matrix for a given time and location. It will be used whenever a new posture is going to be selected.

PostureTransition()

inet::PostureTransition::PostureTransition

(

int

numPosture

)

Construct a posture transition object.

Constructor function of the class.

The parameter is the number of postures which is the dimension of all matrices

It sets the value for t he number of posture. It also suppose the first given transition matrix as default. However, during parsing the xml configuration file, if a matrix has attribute type with value "default", it will be considered as the default (base) transition matrix.

{
    numPos = numPosture;
    defaultMatrixID = 0; // if no default matrix found, the first one will be supposed as the default matrix.

addAreaType()

Adds a area type to the list with the given name and returns the index of this area type in the list.

Creates a new area type instance and adds it to the list.

The boundaries of the area type is empty now. It will be filled later. The function returns the index of the new area type in the list as its output.

addCombination()

bool inet::PostureTransition::addCombination	(	std::string	areaName,

Adds a space-time combination to the list.

This function creates a new space-time combination instance and adds it to the combinations list.

It checks if the given names for area type, time domain, and matrix are previously defined and exist in the corresponding lists. Note that at least area type or time domain should have been specified for a combination. Otherwise the combination is not meaningful. if for example a combination has no area type and just has specified time domain, it means that for the whole simulation area, it will be the same and the proper matrix is selected based on the time.

bool inet::PostureTransition::isMarkovian ( double **  matrix )

protected

Checks if a matrix can be a Markov transition matrix.

Verifies if a matrix can be a Markovian transition matrix.

All elements should be in the range [0,1] and elements of each column of the matrix should add up to 1.

Each element of the matrix should be in the range [0 1]. Further, all elements of each column should adds up to one.

defaultMatrixID

int inet::PostureTransition::defaultMatrixID

protected

The index of the default (base) transition matrix.

If no default is set, the first matrix is supposed as the default. Default matrix is used for the cases that a time or space domain does not lie in any given area types or time domains. It is also used for generating the transition matrix in the case that a steady state vector is given for a space-time domain.
