Unformatted text preview: CSCE 464 Wireless and Mobile Systems Fall 2011 Homework 6 (40 points) Problem 1 (40 points) In this homework you will learn how to read and critique a research paper. A) Read the attached article: S. Keshav, How to Read a Paper, ACM SIGCOMM Computer Communication Review, 2007. Answer the following questions: 1. What is the purpose of the paper? 2. What is the purpose and what are the steps of the First Pass? 3. What is the purpose and what are the steps of the Second Pass? 4. What is the purpose and what are the steps of the Third Pass? 5. What is the process of doing a comprehensive literature survey? B) Following the lessons learned in Part A), act as a reviewer for the attached research paper: Jerome Haerri, Fethi Filali, Christian Bonnet, Performance Comparison of AODV and OLSR in VANETs Urban Environments under Realistic Mobility Patterns. Critique this paper, by answering the following questions: 1. What is the problem addressed in the paper? What are the state of art solutions for this problem? Why the state of art solutions do not completely solve the problem? 2. What is the main idea for solving the problem? 3. What are the assumptions the authors make when solving the problem? Are they realistic or too limiting? 4. How does the paper solve the problem? What are the technical details? Are they sound? 5. Does the paper provide complete, strong evidence that the proposed solution is bet- ter than state of art solutions? Is performance evaluation thorough and convincing? Do the results support the claims made in the Abstract and Introduction about the contribution of the paper? Survey this paper, by answering the following questions: 1. How does the average velocity affect PDR? How can you explain this? 1 2. What is the purpose of Figure 3 in the paper? What conclusions are drawn from that figure? 3. How does CBR data rate affect PDR? How can you explain it? 4. How does CBR data rate affect Routing Overhead? How can you explain it? 5. How does CBR data rate affect the Delay? How can you explain it? 6. How does CBR data rate affect the Average Number of Hops? How can you explain it? 7. How does node density affect PDR? How can you explain it? 8. How does node density affect Delay? How can you explain it? 9. How does node density affect Average Number of Hops? How can you explain it? 2 How to Read a Paper S. Keshav David R. Cheriton School of Computer Science, University of Waterloo Waterloo, ON, Canada [email protected] ABSTRACT Researchers spend a great deal of time reading research pa- pers. However, this skill is rarely taught, leading to much wasted effort. This article outlines a practical and efficient three-pass method for reading research papers. I also de- scribe how to use this method to do a literature survey....
