Aloha - Slotted Aloha Systems - Multiple Access Schemes - Engineering Assignment Help

Assignment Task :

Problem 1: 

Briefly discuss the technology and capacity behind each of the following standards:

• IEEE 802.11a: 

• IEEE 802.11b: 

• IEEE 802.11c: 

• IEEE 802.11d: 

• IEEE 802.11e: 

• IEEE 802.11f: 

• IEEE 802.11g: 

• IEEE 802.11h: 

• IEEE 802.11i: 

• IEEE 802.11n: 

• IEEE 802.11ac: 

Problem 2: 

In a bus 1-persistence CSMA/CD with Tp = 50 μs and Tfr = 120 μs, there are two stations, A and B. Both stations start sending frames to each other at the same time. Since the frames collide, each station tries to retransmit. Station A comes out with R = 0 and station B with R = 1. 

Ignoring any other delay including the delay for sending jamming signals, answer the following questions:

1. Do the frames collide again?

2.  Draw a time-line diagram to prove your claim. 

3. Does the generation of a random number help avoid collision in this case?

Problem 3:

1. Discuss in details the Aloha/Slotted Aloha systems (give the details of theoretical formulation for finding the max throughput in each case). Draw the throoughput curves for both systems.

2. Discuss all the Carrier Sense Multiple Access schemes.

3. Discuss the Ethernet and show the Random Access scheme that is the closest to Ethernet.

Problem 4: 

Parts of the following question has been discussed in class but not all. So, you will need to do some research to answer all parts:

Some of the emerging communication technologies/protocols used by IoT are listed below. Briefly discuss each and give its pros and cons:

1. BLE: 

2. LoRaWAN:

3. NFC:

4. Wi-Fi HaLow:
