Apparatus and method for transmitting data based on cooperation of member nodes belonging to multicast group

摘要

Methods and apparatuses for transmitting data based on cooperation of member nodes belonging to a multicast group is provided. The method may include transmitting multicast packets through a first communication network to member nodes belonging to a multicast group and the member nodes receiving the same multicast packets; and retransmitting the multicast packets upon determination that no member node has completed reception of the multicast packets.

1. A method of transmitting data, the method comprising:
receiving, at a member node of a multicast group, multicast packets from a base station through a first communication network; generating a first network coding packet using the multicast packets based on an error generation rate in the multicast packets; transmitting the first network coding packet to other member nodes of the multicast group through a second communication network; determining the error generation rate in the multicast packets; and collecting the multicast packets received from the base station and a second network coding packet received from the other member nodes in response to the error generation rate being greater than or equal to a predetermined threshold value.
