K.Sivagurunathan, K.Manojkumar, D.Sounder, Midhun Sebastian

Mobile Ad hoc Network (MANET) is an autonomous system which consists of a collection of selfconfigurable mobile node connected through wireless links. This kind of network is also known as infrastructure less networks. These networks have no centralized administration. Security is a major issue in MANET. Black hole attack and wormhole attack are the most severe attacks those occur in MANET. It is difficult to detect those attacks. In this paper, we analyze the nature of black hole attack and wormhole attack in mobile ad hoc network. Analyzing the attacks, we propose a mechanism called Advanced OLSR (AOLSR) protocol is acts as the proactive routing protocol as its nature. The experiment results show that our protocol achieve routing security with 22% increase in packet delivery ratio, 27% reduction in packet loss rate, 42% increase in throughput and 69% reduction in packet end to end delay than standard OLSR.
