  • Apparatus and method of performing discovery based on priority level in distributed network, and method of determining discovery back-off time
    Patent number: 9009248
    Abstract: 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.
