wireless network in which some nodes are decentralized as well as self-organized
in a wireless local area network. In recent years, insider threats increasingly
damage the works not only in computer information systems, but also many
wireless communications systems e.g. WANETs. We must take into consideration
that the majority of insider threats come from users who are fully authorized
to use the WANET systems they are accessing. Due to these kinds of
situations, a Cooperative Trust Bit-Map Routing Protocol (CTBRP) using an
n-Bits Cooperative Trust Bit-Map Routing Table (n-CTBRT) is proposed to be
used against insider threats in WANETs. This CTBRP proposes using a Generic
Algorithm in this paper for establishing cooperative evaluating trust values.
Each node evaluates her/his neighboring nodes in order to reduce the untrusted
routes. Thus, it could reduce the damage away from the insider threats in a
WANET. This approach is one of behavioral-based techniques. In fact, the
compromised nodes or selfish nodes or non-honest nodes will be evaluated as
having low trust values or scores. Once a relay node had been compromised or
damaged by insider threats in this WANET, the communication system will use
this approach to find out about it according to its abnormal behaviors.
Therefore, the proposed routing protocol in the WANET could evaluate the
wrongful behaviors of the compromised node or a selfish node efficiently in
order to prevent InTs. Keywords: cooperative
