Enhanced secure and efficient routing algorithm for optimal multimedia data transmission

Wireless Multimedia Sensor Networks (WMSNs) are critical for various applications requiring reliable and secure data transmission. Enhancing routing protocols in WMSNs is essential to improve performance and security. Existing routing techniques, such as LEACH, Directed Diffusion, and AODV, often suffer from high energy consumption, limited throughput, and vulnerability to security breaches. These limitations hinder the overall efficiency and reliability of WMSNs. Conventional methods struggle to maintain low latency and high data integrity under increasing network loads, leading to performance degradation. This study proposes the Enhanced Minimum Distance Secure Routing Algorithm (EMDSRA), designed to optimize energy efficiency, increase throughput, and enhance security in WMSNs. The dataset comprises simulations with node densities of 100, 200, 300, 400, 500, and 600 nodes, evaluating metrics such as energy consumption, data throughput, latency, and security. Experimental results show that E-MDSRA reduces energy consumption, increases throughput and significantly improves security metrics compared to existing techniques. Specifically, E-MDSRA shows an improvement in data integrity and reduction in unauthorized access incidents. In comparison, Directed Diffusion and AODV also show improvements, but EMDSRA outperforms them across all evaluated metrics. In conclusion, E-MDSRA demonstrates substantial improvements in network efficiency and security, making it a robust solution for future WMSN deployments.
