What is the average time for a successful transmission

Reference no: EM131215102

In given exercise let the transmission time be T_t seconds for a packet. If the packet was received incorrectly, then a message is sent back to the transmitter that states that the message was received incorrectly. Let the time for sending such a message be T_i .

Assume that if the packet is received correctly that we do not send an acknowledgement. What is the average time for a successful transmission?

Exercise
A communication system sends data in the form of packets of fixed length. Noise in the communication channel may cause a packet to be received incorrectly. If this happens, then the packet is retransmitted. Let the probability that a packet is received incorrectly be q .

Determine the average number of transmissions that are necessary before a packet is received correctly.
