Final Project Presentation


Microsoft mesh networks

Microsoft Mesh Networks

Mesh Connectivity Layer

Platform of implementing ad-hoc routing and link quality measurement.

A loadable Microsoft Windows driver.

Use Link Quality Source Routing which is a modified version of DSR protocol

The MCL driver implements an interposition layer between the link layer and the network layer.

Final Project Presentation


Mesh connectivity layer

Mesh Connectivity Layer

Advantages

Higher layer software such as IPv4,IPv6 and DHCP runs unmodified over the ad-hoc networks.

Ad-hoc routing can run over the heterogeneous link layers as the virtual MCL networks adapter can multiplex several physical network adapters, so it can extend across heterogeneous physical links.

MCL supports other ad-hoc routing protocols as well.

Steps

Prepare Wireless Network Interface Card

4 network Interface cards

Installation

Configuration

Create SSID (Wireless Network Name)

Create Channel

Configure IP Address

Software Installation

Steps

Download MCL Tools

Installation

Boring:some MCL software component may not work in windows OS. Per my knowledge, all components except virtual components can works.

Configuration

Configure MCL Virtual Adapter IP Address

Bound MCL Virtual Adapter –Key!

Unbound Local Network Adapter

Performance evaluation

Performance Evaluation

Low Speed

Final Project Presentation


Performance evaluation1

Performance Evaluation

Unstable Network

the connections are always timeout.

even if one hop, the connection is also fragile.

lots of factors infect the ad-hoc stability

distance

assimilation

Delay & Jitter

Longer delay

Serious Jitter

Source “Download”

The source listed on http://research.microsoft.com/mesh is just MCL. Actually, related dynamics link library (.dll) are necessary.

Fortunately, I get the help of three NMU students who maybe are Prof. Wu’ students.

My work

source code analysis

Modification

Increase the packets size

Increase time to live (TTL)

My Understanding maybe is not right.

Final Project Presentation

Improvement

Modification

Increase the packets size

Increase time to live (TTL)

Result

No obvious performance improvement

Increase time to live (TTL)

Why

Nodes number is small

Other reason that I don’t consider.
