Prevention of Routing Attack in Mobile Ad-Hoc Networks: A comparative study
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2012, Vol 1, Issue 5
Abstract
Mobile ad hoc networks (MANET) is a wireless network where nodes work in standalone fashion. The MANET faces various security challenges due to the environment in which it is deployed. The nodes of mobile ad hoc networks are thus susceptible to compromise. The networks are particularly vulnerable to denial of service (DOS) attacks launched through compromised nodes or intruders. One of the major attacks on MANET is denial of service (DOS) attack, which is caused by intruders or malicious nodes. The Flooding attack is one of the DOS attack against on demand routing protocols. In this attack a malicious attack broadcast bulk route request (RREQ) so that all links get overloaded and all bandwidth is consumed. The intruder broadcasts mass Route Request packets to exhaust the communication bandwidth and node resource so that the valid communication cannot be kept. When the intruder broadcasts exceeding packets of Route Request, the immediate neighbors of the intruder record the rate of Route Request. Once the threshold is exceeded, nodes deny any future request packets from the intruder To encounter this attack this paper suggests a mechanism where a node is either member or guest’s based on the trust value and their relationships with their neighboring nodes. RREQ received from members are accepted and RREQ from guest are accepted only after integrity check of the packet and forwarded to other neighbors. The results of our implementation show FAP can prevent the Ad Hoc Flooding attack efficiently.
