Enhancing QoS for Streaming Video Over WLANs
Source: San Diego State University
Recent times have seen a tremendous surge of multimedia traffic over the Wireless Local Area Networks or WLANs. However, the bandwidth intensive multimedia traffic takes the most brunt when a WLAN is overloaded. Longer packet delay, jitter and lower throughput deteriorate the video quality significantly at the receiving end, thus diminishing the user experience. In this paper, the authors implement a new scheme to guarantee Quality of Service (QoS) for resource intensive traffic such as video even in times of resource scarcity in the network. They accomplish this by prioritizing certain (But not all) video packets and ensuring resource allocation to these packets over others.
