Optimization of Handover Delay during Authentication

Abstract

In this work, the significant problem of optimal handover delay in NGN authentication was considered. This study reports an innovative Authentication, Authorisation and Accounting (AAA) architecture together with a far-reaching authentication efficiency enhancement across various networks based on the Universal Seamless Network Access Protocol (USNAP). This research employs a cloud-based AAA server and introduces the concept of a validity certificate (VC) to achieve fast user authentication. The performance of the proposed system is analysed via extensive simulations performed in NS-2. The results show a significant reduction in handover latency, with an average service time of 1.13 ms and a total handover delay of 77.47 ms, demonstrating that it is able to reduce the latency of previous approaches by roughly 13%. With this approach, the USNAP protocol can encode the type of network faster than current protocols and perform account verification. It is capable of scaling massively in our system with high service probability as the user needs grow. This work is helpful for securing light-weight and high-quality network signal authentication methods in NGNs and can be used seamlessly across various types of networking technologies.
