Analysis of security attacks in AODV

An ad hoc network is a collection of mobile devices that communicate in a self-organized way using wireless network interfaces without neither centralized administration nor fixed infrastructure. In such a network, nodes must cooperate with each other so as to extend their transmission range to reach distant nodes. This cooperation requires a specific ad hoc routing protocol to establish and maintain routes between nodes. Ad hoc routing protocols are based on mutual trust between collaborating nodes and suppose a correct behavior. As a result, these networks are particularly vulnerable to various security threats. , and therefore, security is a more significant issue than infrastructure-based wireless networks. In this paper, we present security analysis of the Ad hoc On-demand Distance Vector (AODV) routing protocol to identify all possible security threats that can target its algorithm, such as resources depletion, blackhole, wormhole and rushing attacks.
