The wakeup problem in synchronous broadcast systems (extended abstract)
Leszek Antoni Gąsieniec, Andrzej Pelc, David Peleg · 2000
This paper studies the differences between two levels of synchronization in a distributed broadcast system (or a multiple access channel). In the globally synchronous model, all processors have access to a global clock. In the locally synchronous model, processors have local clocks ticking at the same rate, but each clock starts individually, when the processor wakes up.
