An ad hoc network is a collection of mobile stations forming a temporary network without the aid of any centralized coordinator. Internal threats due to changes in the node behavior that target the routing discovery or maintenance phase of the routing protocol (CA-AOMDV) which applies a preemptive handoff strategy to maintain reliable connections by exploiting channel state information. Using the same information, paths can be reused when they become available again, rather than being discarded. And security challenges can however lead to insecure communication in MANETS.
