Abstract

Abstract:Wireless senor network is one of the emerging technologies where it provides various kinds of applications for military and societal purpose.The sensing methodology which is a combination of wireless communication and processing power makes it as one of the powerful technology. Incorporating security into wireless sensor network is one of difficult task due to their limitations. Wireless sensors networks are prone to various kinds of threats.One of the security attacks to wireless sensor network is a black hole attack. In black hole attack, the malicious node will advertise itself stating that it has the shortest route to the destination by exploiting routing protocol. The black hole attack is a kind of denial of service attack. This paper deals with the architecture of sensor network with access point, vulnerabilitiesof adhoc on distance vector routing protocol associated with black hole attack and detection mechanism. To detect black hole attack in the network, authentication mechanism and sensor network with mobile access point using Adhoc On Distance Vector Routing protocol is used.To detect the number of black hole nodes present in the network, fusion rule is used. The fusion rule used in this paper is q-out-of-m rule, which provides good tradeoff between false alarm rate and miss detection rate.
