Note : This problem is easy if you have completed Problem 8 that says: a) When there are N active nodes, the efficiency of slotted aloha is Np(1-p)N-1.
Poisson process with rate, g attempts per slot.On the other hand, in slotted aloha the probability of successful transmission is SG*e-G.False Ethernet only provides connectionless service to the network layer.Definition Of Slotted aloha.True, the maximum efficiency of slotted aloha is higher than the maximum efficiency of pure aloha.True In CRC (Cyclic Redundancy Check carte da gioco brescia the generator polynomials used by the sender and the receiver need not be the same.True Ethernet only provides unreliable service to the network layer.Synchronization, the time is not globally synchronized.In pure aloha, whenever a station has data to send it transmits it without waiting whereas, in slotted aloha a user wait till the next time slot beings to transmit the data.He proposed to divide the time into discrete intervals called time slots.False Link layer also needs to provide flow control.
