The Communication Simulation brings "the real world" into the simulation. Since the sensors in the simulation do not communicate through a physical medium it is necessary to determine the connectivity within the network. Thus all communication between sensor is channelled through it to check the reachability first.
At the moment the Communication Simulation is not used, since the simulation is based on the assumptions that communciation between all components in Sensor World is possible.
The interface of the communication simulation has two important aspects. In the first place the simulation needs information about the structure of the sensor network (input methods) and secondly methods for determining the connectivity are necessary (reachability methods) .
In order to define a restricted communication the Abstract Communication Simulation class has to be implemented together with the methods to construct a model of the communication network and to ask for the reachability.
