Introduction to WiSS (1)  WiSS: Video multicasting application in ad-hoc networks  Multicast http://en.wikipedia.org/wiki/Multicasting

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 open media at the client.

Hardware/Software Requirements  VLC media player  Java & Java Packages -DatagramPacket -DatagramSocket -MulticastSocket
