In our proposed protocol the mobile station is responsible for generating of authentication token AUTN and random number RAND . The home location register is responsible for comparison of response and expected response to take a decision. Therefore the bottleneck at authentication center is avoided by reducing the number of messages between mobile and authentication center. The authentication time delay call setup time and signalling traffic are minimized in the proposed protocol. A fluid mobility model is used to investigate the performance of signalling traffic and load transaction messages between mobile database such as home location register HLR and visitor location register VLR for both the current protocol and the proposed protocol. The simulation results show that the authentication delay and current load transaction messages between entities and bandwidth are minimized as compared to current protocol. Therefore the performance and the authentication delay time have been improved significantly. Copyright 2006 J. Al-Saraireh and S. Yousef.
