ABSTRACT

As for overlay multicast which provides media streaming, it should cope with dynamic changes in nodes rapidly, and requires methods for error-recovery that take into data bandwidth that each node can process and time during which the node stay on the system. Therefore, this paper uses the characteristics of Bandwidth-Ordered Tree and Time-Ordered Tree for constructing a stable tree in a dynamic environment, and suggests Stay-Time Tree that has Stay Index for efficient error recovery. This algorithm is a method that forms the recovery group, considering the characteristics and time during which each of nodes stays on the system, so that it may be applied to wire & wireless P2P network in an integrated manner. It was found that recovery using this method improved communication reliability about 20%, compared to the existing method.
