Your report should provide clear justifications for each design decision and demonstrate through simulation outputs how the architecture would handle increasing data loads and device count. The final deliverable must show comprehensive planning and technical knowledge applicable to practical IoT system deployment.

Objective: This task challenges you to design and simulate an end-to-end sensor integration scenario within an IoT environment. You will develop an integration strategy for various types of sensors and create a simulated data acquisition system that captures, processes, and forwards data efficiently.

Expected Deliverables: A well-documented integration plan submitted as a digital file (PDF, DOCX, or a well-commented code repository file) that includes sensor selection, configuration settings, and data acquisition strategy, along with simulation screenshots or output logs.

Key Steps:

• Detail the protocols used for communication between sensors and the central unit (e.g., MQTT, CoAP) and discuss how these choices affect performance and reliability.

Evaluation Criteria: Your project will be judged based on the technical viability of the sensor integration approach, depth of simulation details, and explanation of data acquisition strategy. The deliverable should clearly articulate the implementation process and demonstrate practical competence in handling sensor-based IoT integration, ensuring that the data pathway is both efficient and secure.

Objective: This task involves exploring and simulating different IoT communication protocols. You are required to select one or more protocols (such as MQTT, CoAP, or HTTP for IoT) and demonstrate their functionality via simulation to ensure reliable and efficient communication between devices.

Evaluation Criteria: You will be evaluated on the clarity and technical accuracy of your integration process, the effectiveness of your simulation, and the detail provided in your analysis report. Practical evidence of troubleshooting and iterative testing, as well as the ability to integrate heterogeneous devices into a unified system, are critical aspects of this evaluation.

Objective: Security is paramount in IoT systems. In this task, you must implement a security protocol within an IoT simulation environment and conduct a comprehensive vulnerability assessment. This involves identifying potential security risks, testing mitigation strategies, and ensuring system integrity under simulated cyber-threat scenarios.

Key Steps:

• Identify common security vulnerabilities in IoT networks such as unauthorized access, data breaches, and distributed denial of service (DDoS) attacks.
• Configure security features in an IoT simulator by incorporating encryption protocols, authentication mechanisms, or network segmentation.
• Create simulation scenarios that intentionally expose these vulnerabilities to test your configurations.
• Document your step-by-step approach to implementing security measures and the specific tools or frameworks used in your simulation.
• Analyze the outcomes of the simulated attacks to assess the effectiveness of your security implementations and propose further improvements if needed.

Evaluation Criteria: Your project will be assessed based on the technical depth and comprehensiveness of the security solutions implemented, the quality of your vulnerability analysis, and the clarity of your reporting. An effective submission will not only demonstrate practical deployment of IoT security protocols but also critical thinking in identifying and mitigating potential vulnerabilities in integrated systems.

Objective: The final task requires you to integrate the concepts learned throughout the internship into a single, consolidated project. Your goal is to optimize an existing IoT system configuration by enhancing performance, reducing latency, and ensuring robust operational reliability. This task serves as a synthesis of all previous tasks.
