=ICT752: Seminar in Modeling and Simulation of Networks=

**//__Lecture Material__//**

Semester:
Fall 2009

Instructor:
Dr. Sayeed Ghani



=Course Description= This is an advanced PhD level research seminar that focuses on research issues in data and telecommunications networks. Students taking this seminar must already have selected their PhD research topic and will be required to present their ongoing research in a series of presentations. Discussions will be focused around individual research topics. The objective of the seminar shall be to cover in depth individual research topics and to develop these into publishable research. Students will be required to give a series of seminars on their research topic throughout the semester.

//Prerequisites: **ICT552 or ICT651.** //

Course Outline
The course will be based on a) Individual discussions and supervised research b)  Series of three seminars to be conducted by the PhD students on individual research
 * Format: **

Attendance shall be marked on both of the above.

Topics covered will depend on individual research areas. The following topics are expected to be covered, based on ongoing current research areas: Students will be expected to verify their theoretical models with simulations. Possible simulation solutions to be used and explored include Qualnet and NS3/NS2.
 * Topics: **
 * Call Admission Control in Wireless Networks. In particular CAC application in Voice over WiFi networks (802.11e).
 * Block Acknowledgement and a new Head of Burst mechanism in 802.11e.
 * Routing issues in MANET.
 * Simulation: **

Text Books
//Mostly research papers will be used.//

**A. Mobility **  **Exercise No. 1 - Without Mobility**

media type="custom" key="4340325"   media type="custom" key="4340489"
 * Based on Chapter 7 "Advanced Network Modling" of the Qualnet-4.5-Product Tour, construct a36 Node Wireless LAN based simulation with No Mobility
 * CBR connection between Node 1 and Node 36
 * Conduct the simulation to achieve the following result of the simulation run.
 * Exercise No. 2 - With Mobility**
 * Now repeat the above with mobility of nodes, using Random Way Point routing, to achieve the following result:
 * 

B. Understanding Queuing **  
 * Exercise No. 3 - Queue Animation**

media type="custom" key="4340375" 
 * Based on Section 3.3, pg 75, "Queue Animation" of the Qualnet-4.5.1-User Guide, construct a 4 Node Wired LAN based simulation
 * Conduct the simulation to achieve the following result of the simulation run. Note: The bottleneck link should have a bandwidth of 100kbps.
 * This video demonstrates the queuing of packets on a slow link. Two priorities of traffic (p1 and p2) share the link 3-4. Note that the third (leftmost queue) represents p0 which is not present. The p1 queue fills up first as it is of lower priority. p2 queue empties first as it is of higher priority.
 * Note: It //seems// there is a mistake in the User Guide, where it refers to p2 as non real time (pg 77). Since p2 seems to have the highest priority it should be real time, and p0/p1 which seem to have lower priority should be non real time.(needs verifications)

 * Exercise No. 4 -** **M/D/1 Queue simulation**


 * Construct an M/D/1 queue with the simulation as demonstrated below with the following details: 2 Nodes linked with a wired 1 Mbps link; VBR application from Node 1 to 2 with 512 Byte fixed size packets, and inter-arrival time exponentially distributed with specified average inter arrival time
 * The M/D/1 equation for Average Waiting Time in queue is:
 * To calculate average service time you need to add 56 Bytes of overhead: UDP-8+IP-20+MAC/Phy-28 to the 512 Byte VBR packet to total 568 Bytes of transmitted.
 * Conduct the simulation as demonstrated below. The excel sheet is attached here: [[file:F09-Qualnet-v1.5.xlsx]]

**Exercise No. 5 -** **M/M/1 Queue simulation**

media type="custom" key="4340397" []
 * Construct an M/M/1 queue with the simulation as demonstrated below using the Traffic-Gen application.


 * Exercise No. 6 -** **WiMax simulation**

media type="custom" key="4340401"
 * Based on Chapter 8, pg 31, "WiMAX Scenario" of the Qualnet-4.5-Product Tour, construct a WiMAX network for any city of your choice. The Demo below is for Karachi, showing 2 handovers performed as a car moves from one end of the city to another, while connected using a 400 Kbps CBR connection to an office.
