Abstract:
1. A discovery method of a hardware network node in a distributed network, comprising: determining a discovery back-off time that is a transmission wait time of a discovery message based on levels of priority of the hardware network node; and transmitting the discovery message using the discovery back-off time; wherein the determining of the discovery back-off time further comprises: calculating an increment of the back-off time in accordance with the number of levels of the priority assigned to the network, calculating a range of the back-off time using the increment of the back-off time and the levels of the priority of the hardware network node, and randomly determining the discovery back-off time within the range of the back-off time; wherein, in the calculating of the range of the back-off time, the range of the back-off time is determined between a lower limit value obtained by multiplying the increment of the back-off time by (n−1) and an upper limit value obtained by multiplying the increment of the back-off time by n, when the number of levels of the priority is n.
