11-10-2007 Homework

In the talk, we introduced the evolution of contention based protocols:
1. ALOHA
2. CSMA (Carrier Sense Multiple Access)
3. CSMA/CD (collision detection) -> IEEE 802.3 (Ethernet, 100M, 1Gbps)

Problems:

1. Why does Pure Aloha perform worse than Slotted Aloha?

2. According to Textbook pp. 2-48~2-51, why does 1-persistent CSMA have lower throughput than non-persistent CSMA when generated traffic rate is higher than 1 (G>1)? Why does 1-persistent CSMA have shorter latency than non-persistent CSMA?

What is the key factor which contributes to the integration of various media such as data, voice, and video on a single platform?

3. What are the major differences between wireless and wired communication?

Design Project

Design a wireless network that can be fast deployed in an area under disastrous strikes.
Use powerpoint to prepare a 10-minute slide presentation. For the presentation format, here is one.

The issues here are the communication infrastructures in such areas may have been destroyed due to the catastrophy. There may be no infrastructures at all in the first place.

Optical fiber, ADSL and cable modem alike are based on wired technology. Therefore, it is not viable to deploy in a short time, especially in disastrous areas. That's one of the reasons why people turn to wireless technology in such needs.

Therefore, in the design of wireless network, you may want to minimize the use of wired infrastructure.

Hurricane Katrina may be one of the examples where you can find some clues for this project.
