Why does TCP operate poorly in Wireless Networks? Given an example to illustrate the problem.
How would a wireless power distribution network operate similar to cell networks
Thinking of Verizon Wireless: Does the business operate in a market that is characterized by perfect competition, monopolistic competition, oligopoly, or pure monopoly? Explain how you drew your conclusion about its market structure.
Wireless and Mobile Networks 1) Briefly explain why IEEE 802.11 does not use collision detection. 2)Briefly describe the IEEE 802.11 CSMA/CA procedure. 3) Consider two senders in a CDMA network. The chipping codes of sender 1 and sender 2 are (1, 1, 1, 1, 1, 1, 1, 1) and (1, 1, 1, 1, 1, 1, 1, 1) respectively. Suppose that the two sender send 1 bit each and the combined output is (2, 0, 2, 0, 2, 2, 0, 0)....
TCP flow (WHAT is it, WHEN does it become relevant, WHY is it needed, WHERE would it be used, WHO would need it AND HOW to use it - AN EXAMPLE)
Describe the attacks in wireless networks that are more serious com pared to wired network. What vulnerabilities does mobile devices introduced? What services are provided by 802.11i? What attacks are prevented by 802.11i?

Why wireless links provide lower reliability compared to wired links? You turn on your phone and after few seconds you can see a list of available 802.11 networks. From the 802.11 protocol point of view, how does this happens? Ethernet and 802.11 are both data-link layer protocols designed for wired and wireless networks, respectively. Why a 802.11 receiver expects ACK reception while Ethernet does not have such requirement. Where CSMA/CD and CSMA/CA are used? and what are the differences? What...
Q1) On your own words, explain why does the CSMA/CD algorithm not work in wireless LANs? Q2)How are the stations grouped into different VLANs? Explain each method briefly on your own words and give an example. Q3)There is a set of services expected from the network layer. Explain three of them briefly on your own words
Chapter 18: wireless networks TRUE OR FALSE T F 1. As the demand for broadband Internet access has grown, providers of wired local loop service have responded with increasing reliance on optical fiber and coaxial cable. T F 2. A BWA provider services one or more cells. T F 3. Wireless systems are more expensive than wired systems. T F 4. IEEE 802.16 and the associated WiMAX specification now deal with both fixed and mobile BWA. T F ...
