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...
A data packet is transmitted over a lossy wireless channel with packet error rate 0.3. Most communication systems adopt the Automatic Repeat reQuest (ARQ) protocol. That is, if a packet is successfully (with probability 0.7) or unsuccessfully (with probability 0.3) received, the receiver respectively sends a one-bit ‘ACK’ or ‘NAK’ message (over a separate feedback channel) to the transmitter. After receiving an ‘ACK’, the transmitter will move on to the next packet transmission; otherwise, the transmitter will re-transmit the same...
In the last module you learned a formula for calculating bit rate, R = b/t, that is the number of bits divided by the time. This formula expresses the number of bits that are transmitted over a circuit in a given period of time. In practice, however, we are not only concerned with the number bits transmitted, but also with the number of data bits transmitted over a circuit. The data bits are those that the sender decides to send...
