Inheritance. Module Types Simple and compound modules are instances of module types In describing the model, the user defines module types; instances of these module … For example, given a compound module type named MobileHost contains a mobility submodule of the type IMobility (where IMobility is a module interface), the actual type of mobility may be chosen from the module types that implemented IMobility (RandomWalkMobility, TurtleMobility, etc.) [1][12][13][19][24]. For example, sensor networks have the potential to offer fresh solutions to fault diagnosis, health monitoring and innovative human-machine interaction paradigms.
