Introduction to WiSS (2)

 Features

WiSS done via User Datagram Protocol(UDP)

• to prevent congestion
• received signal
• Thread

and Real-time Transport Protocol(RTP) For Multicast; Establishing Different Multicast Groups in the Same Ad-Hoc Network Quality Problem in Multicast -RTP vs. UDP

• Also in VLC

How does WiSS work?

 Server casts a media only to clients who desire

to watch the media

 Every client can be also a server at the same

time

 A client, who is not in a Multicast Group, can

join the Multicast Group at the middle of a casting session

Future Extension

 Java Media Framework (JMF) in RTP

based server-client communication

 JMStudio, integrated with WiSS GUI, are used to

• pen media at the client.
