Abstract—Nowadays, multimedia data in wireless networks plays an increasingly important role in network services. Wireless standards for multimedia data, such as IEEE 802.11e, have certain effects on network performance. Our paper will propose a solution to evaluate multimedia data performance in wireless networks using a testbed system. Specifically, our research analyzes the performance of multimedia data in wireless networks by simulation to find the optimal set of parameters, then evaluate the proposed set of parameters on a real hardware system (testbed), Experimental results on the testbed system compared to software simulation show that the results close to reality to demonstrate the optimal network performance of the proposed set of parameters.
