I need to configure my code to make retransmission in slotted Aloha in case of collision, how to choose the timer ?

Keep in mind that the other guy (who you collided with) will also try to retransmit. So you need a random factor.

You can start by waiting 1 to 16 slots and if you collide again (6.25% chance both parties picked the same slot) then you wait for 1 to 32 slots and so on.

  • $\begingroup$ @EK.Technology yeah. The more slots you provide the less chance for repeated collision but the longer the potential delay. $\endgroup$ Jan 4 '16 at 18:28
