Packets arrive according to a Poisson process with rate λ. For each arriving packet, with probability p the packet is “flagged”. Assume that each packet is flagged independently. Suppose that you start observing the packet arrival process at time t. Let Y denote the length of time until you see TWO flagged packets.

1.Derive the distribution of Y .

2.Find the mean of Y .

    After traversing a wireless error filled channel packets arrive at a network node according a Poisson Process with rate λ . These packets could have corrupted bits due to the wireless channel which has a bit error probability p . A packet is said to arrive at the node successfully if no bits are in error. The number of bits in a given packet is Poisson distributed with mean μ . Assume that packets are not retransmitted. Find the rate...
