table of contents
Table of Contents
  • Motivation
  • Goals and Scope
  • Technical Problem Description
  • Methodology/Task Assignment
  • Expected Results/Deliverable
  • Ad-hoc routing protocol can be classified into various categories such as :
    • Pro-active or Reactive
    • Multicast
    • Geographical
    • Hierarchical
    • Power-aware
  • Pro-active, or table driven protocols is traditional protocol used in wired networks but for wireless, cost of bandwidth to maintain fresh routing table is too high and reactive, or on-demand method is more popular in ad-hoc. This is a trade-off between bandwidth and packet latency.
  • AODV, DSR, and OLSR are most popular protocols in ad-hoc routing. First two are reactive and OLSR is proactive.
  • On this project, we will measure the performance of AODV, DSR and OLSR and compare them focusing on pro-activeness and re-activeness.
goals and scope
Goals and Scope
  • Goal
    • How does AODV, DSR, and OLSR perform?
    • How Does pro-activeness and re-activeness influence their performance?
  • Scalability of AODV, DSR, and OLSR on increase of traffic and users.
technical problem description
Technical Problem Description
  • Pro-active vs. On-demand
    • Pro-active Routing (OLSR)
      • Configure the routes toward any node before packet transmission
      • Traditional method for Wired Network
    • On-Demand Routing (AODV, DSR)
      • Find the route just before packet transmission
      • Due to the high cost of wireless bandwidth

Trade-off btw Bandwidth and Packet Latency!

technical problem description1
Technical Problem Description
  • Several flavors of TCP due to various variations of algorithms for congestion avoidance
    • TCP Reno
      • On an occurrence of a loss event, reduce congestion window to 1 MSS on a triple-ACK.
    • TCP Vegas
      • Monitor packet RTT, trying to predict packet loss before it occurs.

How the difference affects on the performance?

methodology task assignment
Methodology/Task Assignment
  • Protocols (link layer)
    • AODV (Reactive)
      • UoBWin AODV (, windows)
      • Kernel AODV (, linux)
    • DSR (Reactive)
      • DSR-UU (, linux)
    • OLSR (Pro-active)
      • OLSR daemon (, windows)
methodology task assignment1
Methodology/Task Assignment
  • Protocols (Transport layer)
    • TCP-Reno
    • TCP-Vegas
    • Performance over AODV, DSL, OLSR
methodology task assignment2
Methodology/Task Assignment
  • Scalability
    • by Number of Hosts
      • Measure throughput of network as # of hosts increases
    • by Volume of traffic
      • Measure throughput of network as volume of traffic increases
methodology task assignment3
Methodology/Task Assignment
  • Experiment
    • Install protocols on machine
      • Notebook : Window or Linux
    • Measuer throughput on 1:1 network
    • Increase Number of hosts
    • Measure throughput
expected results deliverable
Expected Results/Deliverable
  • Concrete data from each test
    • the Number of users, Traffic, Transfer protocol, etc..
  • The best solution for each circumstance/condition
  • Configuration of the feature of each protocol by test
