8 ◾ Security for Multihop Wireless Networks
between the nodes really exists. A different issue is the attackers’ subsequent action
over the traffic to which they have access (e.g., dropping, modification).
Another diversification step in studying attack types in MANETs concerns
those research works that analyze attacks against certain specific protocols, as is
the case of attacks targeting certain routing protocols, such as AODV and OLSR
[8,9]. In this situation, analyzing general features that characterizes the attacks are
completely avoided; their specific causes and effects over the network services are
instead investigated (e.g., faking/flooding/creating RREP (route reply), RREQ
(route request), HELLO, and TC (topology control) packets).
