Reactive routing protocols like Ad Hoc On-Demand Distance Vector Routing
(AODV) and Dynamic Source Routing (DSR)in Ad-Hoc Wireless Networks which are
used in Mobile and Ad Hoc Networks (MANETs) work by flooding the network with
control packets. There is generally a limit on the number of these packets that
can be generated or forwarded. But a malicious node can disregard this limit
and flood the network with fake control packets. These packets hog the limited
bandwidth and processing power of genuine nodes in the network while being
forwarded.
