message is sent to the source node. At the time the error message is received, the hop in error is
removed from the host route cache and all routes containing the hop are truncated.
9.3.3 Security in MANETs
In MANETs, security is one of the most important issues because they are more vulnerable to

MANETs is a challenging task mainly because MANETs share an unprotected radio channel, they
lack a central authority and partnership mechanisms for users, and they have limited resources and
physical vulnerabilities [6].
