Dynamic Load Distribution Cross-layer Algorithm for Video Transmission over IEEE 802.11n WLANs [ READ ]
Lal Chand Bishnoi, Dharm Singh Jat
The advancement of the Internet technologies has brought with it a tremendous amount of multimedia traffic. Medium access coordination function incorporated by using distributed coordination function (DCF) has the limited quality of services (QoS) in Wireless networks. So it is necessary to have a mechanism for QoS on a wireless network that video and voice over Internet protocol (IP) services can run with good quality along with other data services. This simulation analyzed the performance enhanced distributed channel access (EDCA) 802.11n for video transmission in light and heavy load using without mapping, static, adaptive and dynamic cross-layer mapping techniques. The proposed dynamic load distribution cross-layer algorithm gives better average throughput and PSNR value compared against the results derived from EDCA IEEE 802.11n, Adaptive Cross-Layer Mapping, Dynamic Adaptive Cross-layer mapping mechanism and the static mapping algorithm.
