Title: An Analysis of Energy Usage of Energy Efficient Protocols for Routing for Mobile Ad Hoc Networks


1
An Analysis of Energy Usage of Energy Efficient
Protocols for Routing for Mobile Ad Hoc Networks
  • Presented by
  • Jay Elston
  • November, 2007

Contents
  • Project Goals Accomplishments
  • New and Improved
  • Analysis Results
  • Issues Encountered
  • Conclusions
  • Questions

3
Project Goals(What I wanted to do)
  • Duplicate Analysis Results for EAGER
  • Improve on EAGER if possible
  • Compare EAGER with improved version of EAGER and
    other Hybrid approaches (such as ZRP)
  • Use Network Simulation to validate the analysis

4
Accomplishments (What I actually did)
  • (Almost) Duplicated Analysis Results for EAGER
  • Two improvements to EAGER
  • EAGER-C a modification to the geometry of the
    cell periphery
  • EAGER-LR use Location management to make
    inter-cell messaging more efficient
  • Compared EAGER, EAGER-C and EAGER-LR

5
Loose Ends
  • My Analysis did not get the same values that
    EAGER got
  • Probably culprit the Radio Model
  • Did not compare EAGER to ZRP
  • Ran out of time ?.
  • Did not get to the simulation phase
  • Ran out of time ?.

6
Key Accomplishments
  • Analysis of EAGER
  • Including effects of radio model and node density
    changes.
  • Two EAGER Improvements

7
EAGER Improvements
EAGER uses a trapezoidal peripheral area. Minimum
Rc is the cell edge.
EAGER-C uses a semi-circle as the peripheral
area. When Ap is small, so is Rc.
8
EAGER Improvements
EAGER floods the network with location requests
to find a target node.
EAGER-LR uses a location registry to find out
which cell the target node is in.
9
Analysis Results
  • Ran with parameters as close a possible to EAGER
    paper
  • EAGER paper compared EAGER with Reactive and
    Proactive approaches
  • I added comparisons with EAGER-C and EAGER-LR
  • I also adjusted some simulation parameters

10
Comparison of results
My EAGER levels out too soon ? But the overall
shape is similar ?

Changing the radio power by 10x changes the
numbers, but the overall relationships remain ?

Changing the node density or the size of the
network also changes the numbers, but the overall
relationships remain ?
13
Results
EAGER-C offers a marginal improvement to EAGER
EAGER-LR also offers improved performance until
EAGER goes to a single cell.
14
Issues Encountered
  • Duplicating Results
  • Not all factors are documented
  • For the EAGER analysis
  • What were the parameters used for the radio?
  • How did they analyze the reactive and proactive
    routing protocols?
  • Time
  • Was not able to do all analysis I wanted to do
  • Did not get a chance to learn how to use a
    network simulator

15
Future Work
  • Add analysis of ZRP
  • If EAGER is much better than ZRP, then look at
    how to improve EAGER to fix problems with
    node-free areas
  • Network simulation
  • More analysis of use of location registries
  • Note this is a motivating scenario for
    migrating services ?

16
Conclusions
  • Location registries can offer some energy
    efficiency improvements for MANETs.
  • The big issue with energy efficient routing in
    MANETs is establishing routing tables this
    dwarfs the other factors.
