In OMNeT++, you'll need to create a model that represents the Zigbee protocol stack. This typically involves defining modules for the Physical, MAC, Network, and Application layers.

Network Topology:

Design the network topology that you want to simulate. Decide on the number of Zigbee devices, their roles, and how they are interconnected.

Channel Model:

Implement a wireless channel model that simulates the wireless communication environment. You'll need to consider factors like signal propagation, interference, and noise.

Packet Structure:

Define the structure of Zigbee packets and frames. This includes specifying the format of headers and payloads.

MAC Layer:

Implement the Zigbee MAC (Medium Access Control) layer. This layer is responsible for managing access to the wireless medium, including mechanisms like CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance).

Network Layer:

Implement the Zigbee Network layer, which handles routing, addressing, and network management. Consider the Zigbee routing protocols like Zigbee Pro or RPL.

Application Layer:

Develop the application layer for your identity theft prevention use case. This layer will include the logic and protocols specific to your project's goals.

Simulation Scenarios:

Define the scenarios you want to simulate. For example, you might simulate scenarios where Zigbee devices exchange identity-related information and measure the network's performance in terms of security and data integrity.

Simulation Parameters:

Set the simulation parameters, such as transmission power, data rates, and packet sizes. These parameters should align with Zigbee specifications.

Data Collection and Analysis:

Implement mechanisms for collecting and analyzing simulation results. You may want to measure metrics related to network performance, security, and identity theft prevention.

Validation and Testing:

Validate your simulation by comparing results with theoretical expectations or real-world measurements if possible. Ensure that your simulation accurately reflects Zigbee's behavior

Hi Muhammed! Thank you so much for your response, it has been a real eye opener for me .It has thrown more light on how to implement and go further on my research.

I will now read and try to build the model following the guideline you wrote,since I don't know much about Omnet modules.

Looking forward to learn and collaborate with you.

Thank you Again.
