In this paper, the authors propose an adaptive hello messaging scheme for neighbor discovery by effectively suppressing unnecessary hello messages. The proposed scheme dynamically adjusts Hello intervals, and does not increase the risk that a sender will transmit a packet through a broken link that has not been detected by Hello messaging; they call this the Probability of Failure of Detection of an unavailable link (PFD). To estimate this risk, they exploit an average event interval, that is, an average time gap between two consecutive events (i.e., sending or receiving a data packet) on a node.
