A new method for scalable and reliable multicast system for mobile networks

This paper proposes a new method aiming at realizing a scalable and reliable multicast system focused on mobile network. For reliability, retransmission scheme was adopted. The main idea of the proposed method is that network node does take care of error recovery by retransmission instead of a sender or receivers by which conventional methods have been done. Consequently terminal mobility can be dealt with more simple. This paper shows that the proposed method has much better performance compared with existing methods through simulation.
