According to the basic idea of frame aggregation adopted in IEEE802.11 standards, in this paper, a frame aggregation simulation platform applied for Wi-Fi network is designed by using network simulation software NS2. Based on the research on frame aggregation mechanisms, both the channel utilization and the network throughput are analyzed. According to the charac-teristics of mobile-node model in NS2 and that of the Wi-Fi network protocols, a cross-layer design framework is implemented on the platform. Moreover, extensive simulations are carried out to verify the performance of the platform. The simulation results match well with the mathematical analysis, which shows the correctness and the effectiveness of the implemented simulation platform.
