Achieving High Reliability in SAODV by Decreasing False Positive Blackhole Detection Rate in MANET

A MANET is grouping of freely movable nodes or autonomous nodes which are free to join or leave the wireless network without any central control. due to this decentralised management there is security violence in wireless network due to various attacks like grayhole, blackhole, overflow routing table attack, DOS attacks. but here we discuss blackhole attack in MANET which occurs due to malicious nodes in network. to avoid this attack we implement AODV protocol which is less reliable again black hole attack. To overcome the reliability issues in MANET. In this work we achieve the high reliability in SAODV protocol. In this work to decrease false positive detection of blackhole node in SAODV we modified the SAODV protocol. After the modification we achieve the higher reliability in MANET.
