A Cost-effective Modelling of Faster Authentication Mechanism in Vertical Handover for an Effective Latency Control

Background & Objective: Vertical handover is an inevitable operation demanded in the heterogeneous network to offer consistent connectivity to the user's device during migration from home to a foreign network. Existing literature still shows that there is a large scope for addressing the problem associated with providing seamless service if the latency issue associated with authentication is emphasized. Therefore, the proposed system introduces a very simplified architecture that acts as an external agent for collaborating with various forms of network devices that could exist in the heterogeneous network. Methods: An algorithm is formulated that offers significantly faster authentication mechanism by considering two important attributes, i.e., latency and duration. Without using any form of complex cryptography, this proposed system proved that its architecture could successfully minimize significant delay along with proper retention of throughput. Results and Conclusion: The study outcome has exhibited a computationally efficient vertical handover approach in contrast to the existing system.
