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.

After the initialization phase, the MoBAN coordinator decides about the posture and the position of the Logical center of the group (WBAN). The absolute position of the reference point of each belonging node is calculated by adding the current position of the logical center by the reference point of that node in the selected posture. The coordinator publish the position of the reference point as well as the speed and the radius of the local movement of nodes.
