Hi!
Let supposes we have bunch of 8051 systems, and each are connected to each other via a single pin i.e. for example we connect P1.0 of all with each other directly (or through some common medium). Now each system (unit) can be turn ON and OFF any time asynchronously that is non of them can behave as server or as 'common medium' access controller. Also i have speed of each unit like between 110bps to 9600bps. Now i have following questions,
1, What kind of protocol should i use.
2, How i can solve problem of whose going to transmit and whose listen at any given time.
3, How i can manage addition of new unit in medium and removal of any unit from network during its operation.
4, And many other question which i could not remember yet but i will post as i remember.
Thankyou!
