— This paper analyzes the performance of a system architecture for the Authentication, Authorization, and Accounting (AAA), in a scenario where 3G users generate traffic and invo...
We propose a new approach to fault detection and diagnosis in third-generation (3G) cellular networks using competitive neural algorithms. For density estimation purposes, a given ...
— The forthcoming 4G cellular systems will provide broadband wireless access to a variety of advanced data and voice services. In order to do that, these networks will have a sig...
Third generation wireless systems can simultaneously accommodate flow transmissions of users with widely heterogeneous applications. As resources are limited (particularly in the...
— Push-to-talk over Cellular (PoC) is considered as one of important applications in Next Generation Networks (NGN). The main objective of this study is to investigate the perfor...
