Abstract

Some reliable multicast protocols are based on the retransmission tree that is used for the packet retransmission through the tree. In the mobile environment, the retransmission tree should be configured dynamically. The tree should be compact so that the efficient retransmission is achieved, and the link of the tree should be balanced so that the retransmission load is balanced. Although the tree is statically configurable by using the all delay information between nodes in the multicast group, the cost is high and inapplicable to the mobile environment in which the reconfiguration is frequent. In this paper, we propose a simple configuration algorithm of the retransmission tree in the mobile environment.
