DirCast
DirCast

WiFi multicast suffers from several well-known problems such as low datarate, high losses and unfairness. We designed and prototyped DirCast system to solve many of these problems. DirCast requires no changes to the 802.11 MAC or the wireless APs. Software changes are required on clients only if they wish to participate in multicast sessions. DirCast minimizes the airtime consumed by multicast traffic, while simultaneously improving client experience.
