from computer networks a system approach book please answer the following .. .. (Slotted ALOHA): Suppose there are N nodes in a slotted ALOHA network. Every node is trying to transmit a packet at every time slot with probability p, independently of each other. It takes one time slot to transmit a packet. (a) Express the offered load (the average number of packets per time slot that are arriving to the network) in terms of N and p. (b) Showthethroughput(theaveragenumberofsuccessfullytransmittedpacketspertimeslot)isequaltoNp(1−p)N−1....
