Simulator Wireless Sensor Network

Retrieving informative knowledge from the data produced at the time of simulations is the process that is included in observing the findings of Wireless Sensor Network (WSN) simulations. For checking the effectiveness, trustworthiness and strength of the WSN structure and protocols over research, this work is more essential. In terms of the simulation goals, the analysis could enclose different metrics like network lifetime, energy consumption, node connection, packet delivery ratio, latency and throughput. Below is an appropriate direction that we offer you to conduct the analysis of WSN simulation findings:

Step 1: Collect and Organize Simulation Data

Confirm that you have gathered data on all significant metrics for your research throughout the simulation process. Reception logs, message transmission, energy utility logs and time-stamped incidents can be involved in this data. To promote simple observation, arranging this data in an organized style such as JSON, CSV files.

Step 2: Define Key Performance Indicators (KPIs)

According to your simulation goals, detect the Key Performance Indicators (KPIs) which are related highly. For WSN simulations, it is necessary to incorporate the normal KPIs such as:

  • Energy Consumption: It denotes the average energy that is consumed by the network or per node altogether generally.
  • Network Lifetime: The lifespan of a network can be anything like the duration until the last node dies (LND), time until the first node dies (FND) and duration until a particular percentage of nodes die (HND).
  • Throughput: This is the rate where the data is supplied beyond the network effectively.
  • Latency: To move from the origin to the destination, this represents the duration it takes for data.
  • Packet Delivery Ratio (PDR): It is the ratio of packets which are transferred by the source to those obtained by the targeted location.
  • Connectivity: Preserve a linked network topology on different criteria using the strength of nodes.

Step 3: Analyze the Data

Observe the gathered data by employing visualization and statistical tools. For this motive, use the perfect tools such as R, MATLAB and Python with libraries like Seaborn, Matplotlib and Pandas. For every KPI:

  • Statistical overviews like standard deviation, mean, median and others are estimated.
  • To analyze transformations beyond duration, produce time-sequence plots.
  • Interpret the dispersion of values by designing box plots or histograms.
  • For discovering correlations among various metrics, implement heatmaps and scatter plots.

Step 4: Compare Against Benchmarks or Baselines

Contrast your KPIs against baseline conditions or benchmarks, when your simulation focuses on experimenting novel protocols or methods. This differentiation can be performed through:

  • Relative enhancement metrics.
  • When many simulation runs are undertaken, apply statistical importance validation such as ANOVA and t-tests.
  • To contrast efficiency throughout various situations in a visual format, line graphs and bar charts are useful.

Step 5: Draw Insights and Conclusions

On the basis of your data analysis, do the following task:

  • In the simulation outcomes, detect directions, figures and abnormalities.
  • Based on your simulation goals, assess the efficacy of the network.
  • The trade-offs which are included like among network coverage and energy performance must be examined clearly.

Step 6: Document and Report the Findings

By including the below listed aspects, create a thorough document or demonstration of your analysis:

  • An outline of the goals and simulation setting.
  • For data gathering and analysis, prepare the suitable methodology.
  • Your KPIs statistical summaries and visualizations.
  • Differentiation to baseline situations and benchmarks.
  • The effects for real-time WSN deployment and recommendations for upcoming investigation should be involved in the conclusions that are obtained from your analysis.

How to simulate a network of 100 nodes in MATLAB?

In MATLAB, the process of simulating a network of 100 nodes includes various procedures that range from establishing the node locations and network parameters for visualizing the network and simulating interaction among nodes. We provide a procedural flow that directs you to develop an initial simulation of a 100 node network in MATLAB efficiently:

Step 1: Initialize Network Parameters

Initially, begin with describing the important parameters of your network like interaction range, area size and the number of nodes. The following example expects that nodes interact into a particular length in a 2D platform, specifically for easy understanding:

numNodes = 100; % Number of sensor nodes

areaSize = [200, 200]; % Size of the area (e.g., 200m x 200m)

commRange = 30; % Communication range of each node (in meters)

Step 2: Generate Node Positions

Create locations for the 100 nodes inside the mentioned region in a random way.

% Generate random X, Y positions for each node

nodePositions = areaSize .* rand(numNodes, 2);

Step 3: Calculate Node Connectivity

Across the entire interaction range of every other node, examine which nodes are available. Estimating the distance among every duo of nodes and contrasting it to the communication length is a straightforward direction to perform this process.

% Initialize connectivity matrix

connectivityMatrix = zeros(numNodes, numNodes);

% Calculate distances and update connectivity matrix

for i = 1:numNodes

for j = i+1:numNodes % Avoid repeating comparisons

distance = norm(nodePositions(i,:) – nodePositions(j,:));

if distance <= commRange

connectivityMatrix(i,j) = 1;

connectivityMatrix(j,i) = 1; % The matrix is symmetric




Step 4: Simulate Communication

According to your particular simulation objectives, this step can be undertaken. Simulate a basic situation in which every node transfers a message to its neighbors across the interaction length as an instance. To add many difficult data processing or interaction protocols, you can extend this reason.

% Example: Count the number of messages each node sends

numMessages = sum(connectivityMatrix, 2);

Step 5: Visualize the Network

Analyze the network’s formation and connection through the process of visualizing it. Here is a piece of program that is used for plotting the nodes and drawing lines among the nodes which can perform communication with another one.


hold on;

axis([0 areaSize(1) 0 areaSize(2)]);

for i = 1:numNodes

% Plot nodes

plot(nodePositions(i,1), nodePositions(i,2), ‘bo’);

for j = i+1:numNodes

if connectivityMatrix(i,j) == 1

% Draw a line between connected nodes

line([nodePositions(i,1), nodePositions(j,1)], [nodePositions(i,2), nodePositions(j,2)], ‘Color’, ‘k’);




title(‘100-Node Network Simulation’);

xlabel(‘X position (m)’);

ylabel(‘Y position (m)’);

hold off;

Step 6: Analyze the Results

In terms of your goals, observe the simulation findings. Assessing energy consumption figures, recognizing message propagation times and learning network connection can be involved in this task. To retrieve and depict the interpretations, employ the robust visualization and data processing abilities of MATLAB.

Expanding the Simulation

For highly complicated simulations, this simple model initiates the foundation. Think about the below aspects and implement them, based on the necessity of your project:

  • Energy consumption frameworks for every node.
  • Dynamic node activity. Example, mobility frameworks.
  • Collaboration with extremely difficult ecological models or real-time data.
  • Highly advanced communication protocols like routing methods.
