se.sics.cooja.Simulation
A simulation consists of a number of motes and mote types. The motes in the simulation are ticked one by one in a simulation loop. When all motes have been ticked once, the simulation time is updated and then the simulation sleeps for some specified delay time. Any tick observers are also notified at this time. When observing the simulation itself, the simulation state, added or deleted motes etc. are observed, as opposed to individual mote changes. Changes of individual motes should instead be observed via corresponding mote interfaces. @author Fredrik Osterlind
