This paper shows that two well-known spatial and temporal mobility metrics for Mobile Ad hoc NETworks (MANETs) have drawbacks, possibly leading to invalid results. Based on the concept of spatial dependence in the absence of movement among mobile nodes, the authors propose mobility metrics able to promptly capture spatial and temporal dependence among mobile nodes. Through simulation, they compared the proposed metrics over a diversified set of synthetic mobility models. The results revealed that their spatial metrics can capture spatial dependence in scenarios having different levels of node pause time.
