摘要：There are many ways to improve unreliable datagram protocol (UDP) for video streaming applications. One of them is by using negative acknowledgement (NACK). This paper proposed UDP enhancement by using both NACK-based retransmission and medium access (MAC) layer support for uplink video streaming application in WiMAX networks. Mathematical models and analysis are presented to compare protocol performances in relation to delay and packet loss. The analysis is then confirmed through simulations using the ns-2 simulator. The results show that by reducing the number of NACK packets within one video frame and utilizing MAC support could reduce effective loss rate and delay significantly
