1. A pure ALOHA network transmits 200-bit frames on a shared channel of 200 kbps.What is the throughput if the system(All stations together)produces 100 frame per second.(Hints:44.5; 10.5) 2. what is the vulnerable time frame size of pure ALOHA?If the time unit is P then find it out.[Hints: 2P;0.2P]
A 1 Mbps link is used to transfer packets of each 10,000 bits long. This includes 500 bits header. If the channel is error free and 270 msec is the signal propagation time from the source to destination, obtain the efficiency for, (1) Stop and wait protocol. (i) Sliding window protocol with window size of 500. (iii) Sliding window protocol with window size of 10.
A 1-km-long, 10-Mbps CSMA/CD LAN (not 802.3) has a propagation speed of 200 m/sec. Repeaters are not allowed in this system Data frames are 256 bits long, including 32 bits of header, checksum, and other overhead. The first bit slot after a successful transmission is reserved for the receiver to capture the channel in order to send a 32-bit acknowledgement frame. What is the effective data rate, excluding overhead, assuming that there are no collisions?
A link has a transmission speed of 106 bits/sec. It uses data packets of size 1000 bytes each. Assume that the acknowledgment has negligible transmission delay, and that its propagation delay is the same as the data propagation delay. Also assume that the processing delays at nodes are negligible. The efficiency of the stop-and-wait protocol in this setup is exactly 25%. The value of the one-way propagation delay (in milliseconds) ?
A 1 Mbps satellite link connects two ground stations. The altitude of the satellite is 36,504 km and speed of the signal is 3 × 10^8 m/s. What should be the packet size for a channel utilization of 25% for a satellite link using go-back-127 sliding window protocol? Assume that the acknowledgment pawckets are negligible in size and that there are no errors during communication.

The distance between two microwave towers, with the link capacity 100 Mbps, is 24 Km and the speed of the signal is 3 x 10^8 m/sec. If the frame size is 50 KB in the GoBack-N protocol, The approximate link utilization is _in %(. Assume that the ACK packets are negligible in the size and there are no errors during communication ) Correct answer will be appreciated , else downvoted.
The distance from earth to a distant planet is approximately 9 x 10^10 m. What is the channel utilization if a stop-and-wait protocol is used for frame transmission on a 64 Mbps point-to-point link? Assume that the frame size is 32 KB and the speed of light is 3 × 10^8 m/s.
Four stations in an 802.11 LAN infrastructure network are in a polling list. The stations transmit 20 ms voice packets produced by 64 kbs voice codecs. The contention free period is set to 20 ms. Sketch a point-coordination frame transfer with the appropriate values for interframe spacings, NAV and data and ACK frames.
A network has a data transmission bandwidth of 20 × 106 bits per second. It uses CSMA/CD in the MAC layer. The maximum signal propagation time from one node to another node is 40 microseconds. The minimum size of a frame in the network is(bytes).
Plagiarism and wrong answers will downvotes Compute the fraction of the bandwidth that is wasted on overhead (headers and retransmissions) for sliding window protocol using selective repeat on a heavily loaded 50 kbps satellite channel with data frames consisting of 40 header and 3960 data bits. ACK frames never occur. NAK frames are 40-bits. The error rate for data frames is 1 percent and the error rate for NAK frames is negligible. The sequence numbers are 8-bits.
