(Journal of Maritime Research, 2025-03-25) Manivannan, M.; Gokulanathan, A.; Sridevi Devasena, G. ; Srividhya, S.
In this research work we presents a full Python-based simulation framework for the prevention of maritime Collision Prevention through the incorporation of advanced computational techniques. Along with interactive game design principles. The current study explores that the novel approaches to deal with its significant challenges in the maritime domain through a complex 2D ship Collision Prevention simulation. It uses the cutting-edge technologies. Such as Pygame, advanced mathematical modeling, and object-oriented programming. In order to establish a novel methodology in the analysis and mitigation of collision risks in maritime environments. Complex physical interactions are introduced in this simulation framework using algorithms for the purpose of real-time collision detection and dynamic visualization to simulate ship movement. The Ship class has a robust implementation and the advanced mechanisms of the collision responses. A realistic maritime interaction dynamics model in particular the event-driven architecture of a game and completes the package. The study throws light on the possibility of enhancing maritime safety through paython based simulation computational methods. Further it focusing on the important balance between technological innovation and human expertise. It will open new avenues for future research in maritime safety as well in root optimization . Especially artificial intelligence , interactive computational modeling by providing a flexible and extensible platform for collision avoidance analysis.
Robust security for health information by ECC with signature hash function in WBAN
(Indonesian Journal of Electrical Engineering and Computer Science, 2018-07) Sridevi Devasena, G.; Kanmani, S.
Wireless Body Area Networks (WBANs) are fundamental technology in health care that permits the information of a patient’s essential body parameters to be gathered by the sensors. However, the safety and concealment defense of the gathered information is a key uncertain problem. A Hybrid Key Management (HKM) scheme [13] is worked based on Public Key Cryptography (PKC)-authentication scheme. This scheme uses a one-way hash function to construct a Merkle Tree. The PKC method increase the computational complexity and lacking scalability. Additionally, it increases expensive computation, communication costs and delay. To overcome this problem, Robust Security for Protected Health Information by ECC with signature Hash Function in WBAN (RSP) is proposed. The system employs hash-chain based key signature technique to achieve efficient, secure transmission from sensor to user in WBAN. Moreover, Elliptical Curve Cryptography algorithm is used to verifies the authenticate sensor. In addition, it describes the experimental results of the proposed system demonstrate the efficient data communication in a network.
