Efficient Joining and Leaving for Receiver Driven Multicast Congestion Control

Multimedia applications such as video conferencing, multiparty video games, military applications news feeds, video-audio transmission and IP TV etc. are today and next generation demand in user life. Multicast communication is better than broadcast and unicast as communication scheme to handle above stated application. Multicast is one to group communication whereas everyone knows the multicast group address and uses the UDP protocol. So, it suffers with flooding or congestion problem. Many research groups have proposed the mechanism to control the congestion in multicast. The congestion control schemes are based on source driven, receiver driven and hybrid.
