used to demonstrate that overhead function increases with mobility, and these derivatives will be

applied in the mathematical analysis in the rest of the section.

e routing overhead increases with node mobility due to the extra route discovery transac-

tions generated in reactive protocols and the route updates required in proactive routing proto-

cols. We expect that the routing overhead of proactive routing protocols increases more than the

routing overhead of reactive protocols, bec ...
