How to Start Multimedia Sensor Network Projects Using NS2

To stimulate a Multimedia Sensor Network (MSN) projects using NS2 (Network Simulator 2), follow these core procedures:

Steps to Start Multimedia Sensor Network Projects Using NS2

  1. Understand Multimedia Sensor Networks

The Multimedia Sensor Networks has includes the communicating multimedia data such as images, audio, and video over sensor nodes. The main features of MSNs they are:

  • QoS (Quality of Service) needs for the latency and bandwidth.
  • Energy efficiency to extend the sensor life for energy effectives.
  • Routing protocols enhance the multimedia data protocols.
  • Data compression and scheduling packet for the multimedia network.
  1. Install NS2
  1. Install the NS2 from its official repository or use pre-built installers.
    • Use Ubuntu/Linux for smooth installation.

Install required dependencies:

sudo apt-get update

sudo apt-get install ns2 nam xgraph

  1. Validate the NS2 installation:

ns

It should return:

shell

%

  1. Plan Your Project

Choose on the concentrate region for the Multimedia Sensor Network project:

  • Routing protocols: It includes are protocol they are AODV, DSR, LEACH for MSN.
  • QoS optimization: It enhances the optimization for End-to-end delay, jitter, and packet loss.
  • Energy-efficient methods: Improve the node energy usage for energy efficient technique.
  • Compression techniques: It compresses the adaptive compression for multimedia data.
  • Heterogeneous sensors: The sensors nodes through video, audio, and scalar sensors.
  1. Configure NS2 for Multimedia Sensor Networks
  • Step 1: Alter the tcl script we describe the multimedia congestion.
  • Step 2: Used the sensor for CBR (Constant Bit Rate) or video-like traffic patterns.
  • Step 3: Setting the multimedia sources in the tcl script:

set udp0 [new Agent/UDP]

set null0 [new Agent/Null]

$ns attach-agent $n0 $udp0

$ns attach-agent $n1 $null0

$ns connect $udp0 $null0

set cbr0 [new Application/Traffic/CBR]

$cbr0 attach-agent $udp0

$cbr0 set packet_size_ 1024

$cbr0 set rate_ 100Kb

  • Step 4: Create a multi-hop network to simulate sensor nodes.
  1. Energy Model Configuration

We replicate the energy-aware nodes:

# Set initial energy

set opt(initialEnergy) 10

set opt(energyModel) “EnergyModel”

 

# Assign energy model to nodes

$node set energyModel_ $opt(energyModel)

$node set initialEnergy_ $opt(initialEnergy)

  1. Implement Protocols
  • Use the execution of existing routing protocols for sample AODV, DSDV, LEACH, etc and we maintain the multimedia data.
  • Example for AODV:

set val(rp) AODV

  1. Simulate and Analyze
  1. Process for the replication:

ns your_script.tcl

  1. Envision for the replication of NAM (Network Animator):

nam your_script.nam

  1. Used the awk scripts to excerpt QoS metrics such as delay, packet loss, and throughput.
  1. Metrics for Analysis

Examine the performance of the Multimedia Sensor Network:

  • Latency (End-to-end delay)
  • Throughput
  • Energy consumption
  • Jitter
  • Packet delivery ratio
  1. Example Projects
  • LEACH is used to the Energy-efficient for video routing.
  • Designed for real-time multimedia data is QoS-based routing.
  • Congestion scheduling in WSN for adaptive multimedia.
  • Heterogeneous sensor nodes are improving the delay.

Overall the simulation will be successfully demonstrated and illustrated for Multimedia Sensor network with the help of ns2 tool that has contained brief procedures, extension of the simulation along with code snippets. If you did like to know more information we will offered it.
