Performance Analysis of a Multicast Protocol for Wireless Environments

This paper presents a performance study, using both analytical modeling and simulation techniques, of a new end-to-end reliable multicast protocol for use in environments with wireless access. The proposed protocol, known as the Reliable Mobile Multicast protocol (RM2), divides a multicast tree into sub-trees where subcasting is applied within these...

A Reliable Subcasting Protocol for Wireless Environments

This paper presents an end-to-end reliable multicast protocol for use in environments with wireless access. It divides a multicast tree into sub-trees where subcasting within these smaller regions is applied using a tree of Retransmission Servers RSs. RM2 is receiver oriented in that the transmitter does not need to know...
