Evading Flooding Attack in MANET Using Node Authentication

Anup A. Wanjari, Vidya Dhamdhere

Abstract: MANET is becoming wide range application as its more abilities and less cost compare to wired network. We should provide security as MANET is of inherent nature. Attack of flooding is belonging to DOS attacks. Attack of flooding disturbs performance by generating the floods of request packets. It blocks the original data packet, which supposed to travel to destination. It weakens the MANET by consuming power batteries space and the bandwidth. Malicious node flooded the hello packets continuously. So the next node cannot send packets to destination. In this case one of neighbor send the error packet to source and source again start the rout discovery function. SO the hello interval value updated and informs other node securely. This process will avoid attack of flooding considerably. This process calculates packet delay, packet delivery ratio, throughput etc. Algorithm achieved by the AODV and will get test in ad hoc network. It will decrees control overhead by 2 %.

Keywords: AODV protocol, Detection of malicious node, Network authentication, SHA-1 Algorithm
