Lecture Notes

Students are responsible for the material in the references and that in the papers/handouts, if any. The class notes and slides are just "notes"; they may not cover all required material. The instructor will point out the required chapters in the reference books and papers.

As the semester progresses, I will be depositing electronic copies of  my class notes as they become available on this page. My notes are based on the references. Please be advised that online notes are subject to change as courses develops.

1) Introduction to Mobile and Wireless Networks: An overview of 1G, 2G, mobile data services, and WLANs. In addition to an introduction into 3G and beyond 3G networks. A must read references are:

2) RF Propagation - The main sources for this subject are:


3) The Cellular Concept: cellular network fundamentals - capacity expansion techniques. - Traffic Engineering / Erlang C and B models

4) Multiple Access Schemes: FDMA, TDMA, CDMA, and Contention-based schemes

5) Example of a TDMA network - GSM

6) Example of a CDMA network - IS-95 and cdma2000

7) Review material for midterm exam

8) Wireless Local Area Networks - IEEE802.11

9) Mobile IP:

10) Privacy and Security for Wireless Networks - Notes


11) Quality of Service (QoS) for mobile networks


Course Project:

You are required to reproduce the simulation results presented in the following paper:

Changle Li; Jiandong Li; Xuelian Cai;"Performance Analysis of IEEE 802.11 WLAN to Support Voice Services, "Advanced Information Networking and Applications, 2004. AINA 2004. 18th International Conference on , Volume: 2 , 2004.

and possibly extend the study by considering other types of traffic and/or enhancements to the access mechanism. An introductory study into PCF characterization can be found in:

Xiyan Ma; Yi Wu; Zhisheng Niu; Saito, T.; "Performance analysis of the packetized voice transmission with PCF in an IEEE 802.11 infrastructure wireless LAN," 9th Asia-Pacific Conference on Communications, 2003. APCC 2003. Volume: 2 , 21-24 Sept. 2003, Pages:571 - 575 Vol.2


IEEE802.11 standard (size ~ 6 MB)- Please pay special attention to chapter 9 - MAC sublayer functional description. This contains specification for both DCF and PCF functions.

Presentation by Al-Mutairi and Mesmar - from previous COE 541 classes.
