RESERVATION DIVERSITY METHOD OF DISTRIBUTION AND REPLICATION PROTOCOL BASED ON COOPERATION RELAY COMMUNICATION

摘要

PURPOSE: A DRP(Distribution and Replication Protocol) reservation diversity method based on cooperative relay communication is provided to maintain reserved resources by reserving an indirect link which passes through a relay device. CONSTITUTION: If a first indirect path and a second indirect path are able to be reserved, a reservation subject node transmits a reservation detailed state code to a relay node(S44). The relay node transmits the set reservation detailed state code by notifying a relay state to a reservation target node. The reservation subject node transmits the detailed reservation state code to the reservation target node. The reservation subject node receives the set detailed reservation state code. The reservation subject node transmits data via a direct path which is arranged to the reservation target node(S46).
