Welcome to ECE 158B: Data
Networks II
The evolution of wireless networking is trailblazing.
This course is aimed at providing some of the fundamental concepts of wireless networking. It is
estimated that in the near future, the number of wireless devices
connected to the Internet will hugely overtake their wired counterparts.
In this advanced course on Data Networks II, as a continuation of the
Data Networks I (ECE 158A) that focused mainly on wired networks, we
focus on wireless networking. The three different wireless networking
paradigms that will be studied in detail are the following: (i) wireless
wide area networking, (ii) wireless Local Area Networking, and (iii) distributed
wireless networking. If you have any questions or suggestions, please contact the course
instructor
for further information.
NEW! Finals help sheet guidelines: One side of a Letter size paper with at least 0.5 inch margins for all sides can be used to write and bring equations or sentences to help you with the midterm. However, the font size is limited to 11 point fonts on Times New Roman font. If you choose to use handwriting, the letters must be equal to or bigger than 11 point font on Times New Roman font. Calculators are allowed only for computing purpose. That is, equations, potential sequences of steps, answers, or sentences are NOT allowed to be stored in them. PLEASE BRING EXAMINATION BLUE BOOKS FOR ANSWERING. There will be 5 points for neatness of the answers. In addition to the class notes and presentations on WLANs and WMNs, the topics on DSR and DSDV are taken from the book by Murthy and Manoj, ''Ad hoc Wireless Networks: Architectures and Protocols" that is available under course reserves at UCSD Library. Similar to the midterm, the format of the finals will comprise of (i) terms and definitions, (ii) quantitative problems to solve, and (iii) theoretical derivations.
NEW! Class notes for WLANs and WMNs are submitted to library. Ask for the title "Notes on Wireless Mesh Networks and Wireless LANs" under the reserves for ECE 158B: Data Networks II.
NEW! Presentations for the class on 06/04/2009 can be found here.
NEW! Based on the students' requests, you may either do the Matlab-based assignment or a Writeup assignment. You may find the details of both below. Both submission are due on any time Finals week.
NEW! WLAN Assignment/Observation can be found here here . Due: Any time on Finals week.
OR
NEW! For those who have difficulty in working with Matlab or other programming languages, here is an alternative, Writeup assignment, for the Matlab assignment. You may submit either the Matlab assignment or the Writeup assignment. This Writeup assignment is introduced based on the requests from the students at the end of the class. As per this Writeup assignment, you are required to make research summaries of any two of the three following research papers: Paper 1, titled "Context-Aware Routing in Wireless Mesh Networks", can be found here, Paper 2, titled "A Channel and Rate Assignment Algorithm and a Layer-2.5 Forwarding Paradigm for Multi-Radio Wireless Mesh Networks" can be found
here , and Paper 3, titled "Symbol-level Network Coding for Wireless Mesh Networks" can be found here. Note that, some of these web links work only through UCSD network. Summary of each paper must be a minimum of two letter size pages with 11 point times new roman fonts in single space with 1 inch margin all sides. Note that the IEEE Anti Plagiarism policy MUST BE strictly followed in preparing the summary. That means you cannot copy sentences, words, or structures, as you may find here. Also note that verbatim copy, though credited to the original author(s), is not acceptable for this write-up submission. If you want a copy of the papers in email, contact the instructor.
Homework on WLANs can be found here . Deadline anytime on Finals Week.
Presentations for the class on 06/02/2009 can be found here and here .
A sample midterm can be found here . Note that this is only an example of the format of questions that may be considered for midterm.

Midterm help sheet specifications: One side of a Letter size paper with at least 0.5 inch margins for all sides can be used to write and bring equations or sentences to help you with the midterm. However, the font size is limited to 11 point fonts on Times New Roman font. If you choose to use handwriting, the letters must be equal to or bigger than 11 point font on Times New Roman font. Calculators are allowed only for computing purpose. That is, equations, potential sequences of steps, answers, or sentences are NOT allowed to be stored in them. Please bring Erlang-B and Erlang-C graphs/tables with you. Also, please bring answer books/sheets. In addition to the class notes and home work, the two important reference books for Midterm are: (i) Rappaport (Chapters 3 and 11) and (ii) Mischa Schwartz (Chapters 8 and 9). The format of the Midterm will comprise of (i) terms and definitions, (ii) quantitative problems to solve, and (iii) theoretical derivations.
A short talk/presentation on internship opportunities for Networking students will be made in the class on 05/5/2009 by Prof. Rene Cruz, Founder and Chief Scientific Officer, Mushroom Networks, Inc.,
