Disclosed herein are an apparatus and method for transmitting Node Discovery Messages. The apparatus includes a Medium Access Control layer information collection unit, a Discovery Window Slot calculation unit, a DW size determination unit, a DWS selection unit, and an NDM processing unit. The MAC layer information collection unit collects time slot information for NDMs in a previous round. The DWS calculation unit generates information about the slots of a Discovery Window of a discovery frame in the previous round based on the time slot information. The DW size determination unit determines the size of the DW in a current round based on the information about the slots of the DW. The DWS selection unit selects Discovery Window Slots in the current round based on the size of the DW. The NDM processing unit sends the NDMs during respective times corresponding to the DWSs.

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.

Disclosed herein are an apparatus and method for supporting Quality of Service (QoS) in middleware for Data Distribution Service (DDS). The apparatus includes a QoS policy analysis module, a QoS policy management module, and a QoS policy process module. The QoS policy analysis module extracts a set of QoS policies set up by Data Centric Publish Subscribe (DCPS) and associated with publication/subscription, and analyzes the QoS policies. The QoS policy management module determines the consistency of QoS policies of the DDS, and negotiates QoS policies for DDS communication. The QoS policy process module handles the QoS policies of the DDS.
