Wireless networks have become popular in recent years. A number of places such as hotels, airports, coffee shops, offices and increasingly, private homes are equipped with wireless hotspots and access points. Wireless networks are emerging as an alternative to wired networks, and as a result, most of applications that are used on wired networks are now common on wireless networks.Transmission of video over wireless networks comes with a number of challenges. In comparison to wired networks, wireless networks have limited bandwidth, because of the fluctuation in channel conditions which may cause the bandwidth of the wireless link to drop. Wireless networks are also characterized by high packet losses. This poses problems especially for compressed video because data loss causes degradation in video quality. Therefore, the necessity of innovative and effective mechanisms to transmit video streams over wireless environments can be felt.
