  1. EE436 CS422 Wireless Networking Technologies and Aplications Video Multicasting via ad-hoc Network Group 5Ali KaradumanMehmet KopanOnur ÖzbekM.Burak ŞenolInstructors Ezhan Karaşan & İbrahim Körpeoğlu 14/05/2010

  2. 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

  4. 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

  5. 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.

  6. Hardware/Software Requirements • VLC media player • Java & Java Packages -DatagramPacket -DatagramSocket -MulticastSocket
