Mitigation of DOS Attacks on Video Trafficin Wireless Networks for better QoS

Security in wireless computer networks is of great importance because wireless networks are always thought to be as more vulnerable to various types of attacks than ordinary wired networks. This vulnerability is due to the nature of wireless networks that rely on using a wireless shared medium. Video is becoming a more popular type of data being transported in contemporary networks, especially with the advent of many emergent Internet and Mobile applications. To achieve user satisfaction, the transmission of video must comply with a number of quality of service (QoS) requirements. However, network attacks affect in some way or another these requirements. In this paper, we study the benefits of a selected solution to the denial of service (DOS)attackto provide betterQoS of video, which leads to improved performance of various wireless networks.
