A Cross Layer Based Scalable Channel Slot Re-Utilization Technique for Wirele...csandit
Due to tremendous growth of the wireless based application services are increasing the demand
for wireless communication techniques that use bandwidth more effectively. Channel slot reutilization
in multi-radio wireless mesh networks is a very challenging problem. WMNs have
been adopted as back haul to connect various networks such as Wi-Fi (802.11), WI-MAX
(802.16e) etc. to the internet. The slot re-utilization technique proposed so far suffer due to high
collision due to improper channel slot usage approximation error. To overcome this here the
author propose the cross layer optimization technique by designing a device classification
based channel slot re-utilization routing strategy which considers the channel slot and node
information from various layers and use some of these parameters to approximate the risk
involve in channel slot re-utilization in order to improve the QoS of the network. The simulation
and analytical results show the effectiveness of our proposed approach in term of channel slot
re-utilization efficiency and thus helps in reducing latency for data transmission and reduce
channel slot collision.

1) What is the main difference between Pure Aloha and Slotted Aloha? Are there any
circumstances where Pure Aloha would perform better than Slotted Aloha? If so, give
such circumstances/conditions. If no, explain why Pure Aloha could never perform better
that Slotted Aloha.
2) Given a network with 9 routers as shown in the figure below. Assume the utilization of
center-based spanning tree construction, where router D is assigned as the center (or
root) router. Assume routers join the tree in the following order: C, A, H, B, F, G, E, and
I. Show the final constructed spanning tree for that given network.
3) Consider two substitution ciphers. One adds a value of i to the ASCII code of the
plaintext character. The other adds a value of j to the plaintext character. All additions are
modulo 256. Now consider a double-encryption method that adds i to each plaintext
character and then adds j to the resulting ciphertext character to get another ciphertext
character. Again, all calculations are modulo 256 How much more secure is this double
encryption when compared with either single-encryption method? Explain your answer.
4) Consider the bit string 001011010101000011111101001101 and the key 10110. Use the

6) Three broad classes to multiple access techniques exist, which are: channel partitioning,
random access and taking turns. In general, it is assumed that any network would use one
of these techniques or the other. However, cable Internet access networks utilize all three
techniques. Describe how this is done by such networks, and explain how the utilization
of any of these techniques does not conflict with the utilization of the other two.
7) In general, fully-connected topology is exhaustive and very unlikely to be used for the
construction of a network.
a. Are there any clear and significant advantages of such topology? Explain clearly.
b. Explain why it is unlikely that such topology be used for network construction.
You should clearly indicate the major disadvantages of such topology.
c. While this topology seems to make little sense for the construction of networks, in
the general terms, it is actually used as part of Data Centers to connect Tier-1 and
Tier-2 switches. Explain clearly the major advantages of such utilization in data
centers. You should provide some example that shows, through some numerical
values, the obvious advantages of such utilization.

A computer network, or simply a network, is a collection of computer and other hardware components interconnected by communication channels that allow sharing of resources and information. Where at least one process in one device is able to send/receive data to/from at least one process residing in a remote device, then the two devices are said to be in a network. Simply, more than one computer interconnected through a communication medium for information interchange is called a computer network.

NETWORK MANAGEMENT
The Engineering Department to twelve persons in a small corporation is on a regular
10 Base-T Ethernet Lan hub with 16 ports. The busy group started complaining
because of the slow network performance. The network was operating at 50%
utilization, whereas 30% utilization is acceptable. If you are the corporation’s
Information Technology Engineer and have to resolve the problem technically,
a. Describe four choices for resolving the problem, maintaining the LAN as an
Ethernet LAN.
b. State the advantages and disadvantages of each approach.
1. Two virtual LANs, 145.50.50.1 belonging to NM lab, and 145.50.60.1 belonging to
Networking lab, each have three workstations. The former has workstations
145.50.50.11-13, and the latter 145.50.60.21.-23. They are connected to a switched hub
on ports 2 through 7. the NICs (network interface cards) associated with ports are
made by Cabletron and their MAC addresses start with the vendor’s global prefix 00-
00-1D (hexadecimal notation) and end with 11,12,13,21,22, and 23 (same as the fourth
decimal position of IP addresses).
2.
a. Create a conceptual matrix table, as shown below, that would be
generated by the hub that relates the IP address, MAC address,
and port number.
3.
IP Address MAC Address Port Number
b. The workstation 23 is moved from networking lab to NM lab.
The appropriate parameter changes in the hub and the workstation.
3. Design a client/server network with two servers operating at 100Base-T Fast Ethernet
speed and the clients operating at regular 10Base-T Ethernet speed using a 10/100
Mbps NIC. The hub is located in a wiring closet, but the servers and clients are not.
Assume that a satisfactory performance is achieved at 30% utilization of the LAN.
2. 4. Customer network management is used to look at the QoS classes associated with VCIs
across an ATM link interface. What three MIB group and objects are used to collect the
information? Describe the relationships among them.
5. A new LEC is added to an ATM LAN containing other LECs, LES, LECS, a BUS, and a
ATM switch. Starting from the initial conditions, six steps (or phases) are required to
make the new LEC part of the ELAN network: (1) LEC connection, (2) configurations,
(3) join, (4) initial registration, (5) BUS connection, and (6) operation. Describe these
steps.
6. Switched virtual circuit transmission overhead could be high for sending small amounts
of information. Calculate the minimum time required to transmit one ATM cell from
Miami to San Francisco on a basic SONET network (OC-3) for the following cases.
Assume that the distance is 4500 km and that the propagation speed is 300 meters per
microsecond.
a. datagram service
b. switched virtual circuit service
c. permanent virtual circuit service
7. A network manager discovers that a network component is performing poorly and
issues on order to the technician to replace it. Which MIB group contains this
information for the technician to find out the physical location of the component?
8. An IT manager gets complaints from the users that there is excessive delay in response
over the Ethernet LAN. The manager suspects the cause of the problem is excessive
collisions on the LAN. She gathers statistics on the collisions using the dot3Stats Table
and localizes the problem to a single faulty interface card. Explain how she localized
the problem. You may use RFC 2358 to answer this exercise.
9. You have been assigned the responsibility of adding a new vendor’s components with its
own NMS to an existing network managed by a different NMS. Identify the three sets
of functions that you need to do to fulfill your task.
10. In a ballroom dance class, the instructor asks the guests to form couples made up of a
male and a female order (order does not matter) for a dance. Write an ASN.1 module
for dance Group with data type Dance Group that is composed of data type couple;
couple is constructed using male and female.
11. A high school class consists of four boys and four girls. The names of the boys with their
heights are Adam (65”), Chang (63”), Eduardo (72”), and Gopal (62”). The names of
the girls are Beth (68”), Dipa (59”), Faye (61”), and Keisha (64”). For each of the
following cases, write an ASN.1 description for the structure and record values by
selecting appropriate data types. Start with data type Student info, listing information
on each student.
12. You are asked to do a study of the use pattern of 24,000 workstations in an academic
institution. Make the following assumptions. You ping each station periodically. The
message size in both directions is 128 bytes long. The NMS that you using to do the
study is on a 10-Mbps LAN, which functions at 30 percent efficiency. What would be
the frequency of your ping if you were not to exceed 5 percent overhead?
13. Imagine that you are working for a company (maybe you are) that has decided to move
from an SNMP-based to a Web-based management system. You are asked to prepare
3. an executive summary on the two approaches, WBEM and JMX, and make a
recommendation. Present your report, which is not to exceed two pages (executives
don’t have the time or patience to read longer reports).
