Abstract

Objectives: To present a performance evaluation of a WI-FI network under the impact of mobility. It alsomakes the study and the evaluation cover for level 2 and level 3 mobility. Methods/Statistical Analysis: The OPNET simulator was used for simulating the scenarios of proposed architectures. For performance evaluations, the different parameter has considered, such as mobility speed, number of connected users and channel access methods. Findings: The main interest of this paper is to reveal the mobility schema that ensures a better continuity of providing services to mobile users moving between different Wi-Fi access points while considering a number of constraints related to the quality of service. Application/Improvements: Deploying level 2 roaming gives better results compared with level three roaming using MIPv4, while increasing the speed of mobility and the number of clients.
