Ad Hoc Routing Modeling and Mathematical Analysis ◾ 123
erefore, the routing overhead increases with the number of nodes, as stated in Proposition
5.6, and the proactive routing protocols present higher overhead than reactive protocols, as stated
in (5.7.1). Increasing the number of nodes affects more of the proactive protocols routing overhead,
while increasing the node mobility affects more of the reactive protocols routing overhead. For this
reason, proactive routing protocols are not scalable in large ad hoc networks.
Figure 5.11 shows that the end-to-end packet delay is similar in the case of reactive and proac-
tive routing protocols when ...
