Internet of Things Based Secured Data Transmission Protocol for Agriculture Application

In this research, we proposed a protocol for information transmission in a communication system.The protocol consists of three parts: Publisher, Broker, and Subscriber.The main problem in the transmission is the reliability of the broker.It is very difficult to get the status of the broker whether it is active or not.Secondly, we also worked on the part of security.Here by employing a Watchdog timer to determine whether the broker is active or not.To make the system more secure AES algorithm is incorporated into it.To validate the suggested protocol hardware setup is built and performance is tested in various conditions.Performance tests show that our proposed system outperforms the current system when compared to the existing system.The suggested system architecture's temporal and spatial complexity are also presented in this research.
