In the field of the Internet of Things (IoT) and wireless communication networks, secure data transmission remains a critical challenge due to the inherent vulnerabilities and dynamic nature of these networks. Traditional routing protocols often fail to provide adequate security and efficiency, leading to data breaches and communication delays. To address these issues, we propose a Blockchain-Based Greedy Routing Protocol (BBGRP) that integrates blockchain technology with a greedy forwarding strategy to enhance the security and reliability of data transmission in wireless networks. The BBGRP leverages blockchain''s decentralized and tamper-resistant ledger to validate the integrity and authenticity of data packets, while the greedy routing approach optimizes the selection of the most efficient transmission paths. Our method incorporates smart contracts to automate route verification, ensuring secure and real-time decision-making processes. Experimental results show that the proposed protocol significantly reduces the packet loss rate by 27.3% and improves data transmission speed by 35.6% compared to traditional routing protocols. Additionally, BBGRP demonstrates a 42.8% enhancement in overall network throughput and a 21.7% decrease in end-to-end latency. The security analysis confirms the robustness of BBGRP against common attacks, such as Sybil and man-in-the-middle attacks, by achieving a 98.4% attack detection rate. These results highlight the potential of blockchain-based routing protocols to revolutionize secure data transmission in IoT and other wireless communication environments.
