Intrusion Secure Algorithm for AODV

Ekta, Nasib Singh Gill

Abstract: A mobile Adhoc network (MANET) is distinguished by their mobile nodes, multihop wireless connectivity, absence of infrastructure, communicating environment and its dynamic topology. In Ad hoc network routing is reactive on-demand philosophy where the routes are established only when required. Whereas stable routing, security and power efficiency are considered the major issues in this field. As far as the Adhoc environment is concerned, the network is accessible to both the legitimate and malicious nodes. Many security models have been proposed to detect these malicious nodes. The proposed approach named malicious node detection IDS is intended to incorporate security aspect on existing protocols. This paper checks the attacks occurring in MANETS and tries to detect those attacks by understanding the situation in case of attack. Scheme has been incorporated on AODV and results have been calculated using NS2.
