Whenever an ABF has been in the system for more than the time-out interval specified, it is discarded.
A receiving node then determines the time-out for this neighbor which equals the minimum of the neighbors' time-out interval as indicated in the beacon and its own time-out interval calculated from its current speed.
For instance, for the time out of Africa we inferred smaller confidence intervals (36 81 KYA) than those in Gutenkunst et al. (2009) (40 270 KYA).
The time out was set at 3 s, and the intertrial interval was 1.5 s.
In speed-based approach, the beacon interval and neighbor time-out interval are dependent on the speed of node.
However, each node calculates its neighbor time-out interval as a multiple k of the beacon interval.
Nodes send their calculated values of time-out interval in their beacon transmissions.
The former implies that the control operation is activated only when the states enter the certain region which is often pregiven; while the later activates the control only in some finite time intervals; the system evolves freely when the time goes out of those intervals.
Partial correlation coefficients were calculated and regression analysis carried out for the time lag (interval) over which the largest association between these variables was identified.
The result implies that the proposed algorithms can track the variation of the traffic better when shortening the time interval of carrying out the algorithms, which yet increases the overhead of signaling due to the frequent reconfiguration.
It turned out that the time interval in which high temperature and high mechanically induced tensile stresses are acting simultaneously is a major aspect for the damage development.
