Fine doted line is for OLSR, fine dashed line is for AODV

Link duration is defined as the time period that two nodes are in the transmission range. Long-lived link increases network stability.

-The mobility is defined as the relative speed between two nodes.
-The number of link breaks have nearly linear relationship with node mobility
-PDR decreases as mobility increases.

The number of link breaks: measurement for the metric is simple for routing protocols that maintain routing table, because it can be calculated by comparing node degree at time interval. The upper graphs are examples that showing the node degree that three nodes monitored at different simulation time with different mobility, For routing protocol such as DSR, which does not maintain the routing table, still can estimate the metric by monitoring the node degree in its routing cash. The left graph is an example by comparison the real node degree with the from the its route cache.
