SCIDP-Secure cloud-integrated data dissemination protocol for efficient reprogramming in internet of things

Base station (BS) offers data dissemination as a service to IoT smart devices, enabling efficient reprogramming or reconfiguration for their intended activities in post-deployment. Most of the existing IoT data dissemination schemes rely on flooding, leading to the Redundant Broadcast Storm Problem (RBSP), where multiple sensor nodes repeatedly transmit redundant data to neighbours. RBSP elevates network energy consumption and sender congestion in the network. Given that IoT smart devices communicate through open wireless mediums with the internet as a backbone, they are vulnerable to various malicious threats during data dissemination. Intruders may engage in malicious activities and compromise configuration parameters, leading to device failure to execute intended services. This paper proposes a Secure Cloud-Integrated Data Dissemination Protocol (SCIDP) aimed at ensuring the secure dissemination of data within cloud-integrated environments to mitigate RBSP's impact and enhances security for performing effective reprogramming of sensor devices in IoT. The proposed protocol is implemented by using NS3 simulator with realistic simulation parameters. Simulation results indicate that the proposed protocol enhances energy efficiency by 12%, dissemination effectiveness by 16%, and network lifespan by 16%. Furthermore, the proposed system decreases communication overhead by 11% and computational costs by 9% compared to alternative existing protocols. From the formal security analysis, the proposed system proves that it can withstand against various kinds of security attacks in the network.
