In today's interconnected era, the integration of Raspberry Pi and robust security algorithms alongside the burgeoning Internet of Things (IoT) landscape serves as a pivotal force in fortifying privatized network devices against potential intrusions. This amalgamation capitalizes on connectivity as the backbone, facilitating seamless communication and information exchange among myriad devices. With the exponential growth of the Internet, the opportunity to establish private networks has blossomed, emphasizing not only connectivity but also safety. Leveraging emerging IoT technologies, including electronic hardware and protocols, offers new avenues for device interconnection and communication while ensuring stringent security measures are in place. This comprehensive literature review delves into diverse methods, protocols, and middleware platforms enabling the creation of privatized networks for various applications. Highlighting prevalent protocols such as MQTT, VSL, CoAP, AMQP, and the Data Distribution Service (DDS), it emphasizes the significance of real-time, scalable data distribution in distributed systems. Central to the discussion is the integration of Raspberry Pi's versatility and affordability, to ensure the resilience of privatized network devices and enhance the overall integrity and security of IoT ecosystems.
