MoBAN - Classes providing a mobility model for Wireless Body Area Networks

Collaboration diagram for MoBAN - Classes providing a mobility model for Wireless Body Area Networks:

Classes
class	MoBANCoordinator
	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. More...
class	MoBANLocal
	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 through the blackboard. RWMM determines the location of node at ant time relative to the given reference point. More...
class	Posture
	to store the specification of a posture on the MoBAN mobility model. More...
class	PostureTransition
	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.

MoBAN C++ reference

This is the C++ implementation reference for MoBAN, which is a configurable mobility model for wireless Body Area Networks. MoBANCoordinator and MoBANLocal classes describe the behavior of the Coordinator module and local mobility module of the MoBAN, respectively. There are two more classes which are used in the coordinator module.

Class Posture is responsible for maintaining an instance of defined posture for the WBAN. In the initialization phase, the MoBANCoordinator reads the input posture specification file (.xml) and makes a list of posture classes, each maintaining the information of one defined posture.

Class PostureTransition is responsible for maintaining the configuration information regarding the spatial and temporal correlations in posture selection strategy of MoBAN. In the initialization phase, the MoBANCoordinator reads the input configuration file and pass the given information about the area types, time domains, various Markov transition matrices, and the setups which specify which matrix should be used in a particular space-time combination. During the simulation run, the class provides a function that determines the proper Markov matrix for a give time and location.
