Disclosed herein are an apparatus and method for discovering a communication entity. The apparatus for discovering a communication entity includes a list generation unit for generating a list of connection target Data Readers (DRs), a counter generation unit for generating a counter including information about a number of the connection target DRs, and a discovery message communication unit for establishing communication connections to the connection target DRs based on the list and the counter. The discovery message communication unit includes a transmission unit for transmitting a DR discovery message including data topic information or possible service quality information to each of the connection target DRs, and a reception unit for receiving a Data Writer (DW) discovery message including data topic information or possible service quality information from each of the connection target DRs.

Method and apparatus for discovering communication entity

Provided are a network node and a method of performing discovery, which may stably perform discovery without delay or crash of a network at the time of initial discovery in a large-scale network. The network node operated in a distributed network includes a discovery performing unit that determines a discovery back-off time that is a transmission wait time of a discovery message based on levels of priority of the network node, and a communication unit that transmits the discovery message using the discovery back-off time.
