Security issues in MANET are a testing assignment these days. Because of its dynamic nature MANET are more vulnerable to attacks. Especially, a blackhole attack refers to an attack by malicious nodes which forcibly acquires the route from a source to destination by falsely reporting the shortest hop count to reach the destination node. Selective blackhole attack is a special kind of blackhole attack where malicious nodes drop the data packets selectively. If selective blackhole attack exists in a network and if a node tends to acts with malicious behavior IDS technique is implemented to maintain the reliability. This technique increases the efficiency of the network. This study proposed a modified routing protocol called Enhanced OLSR (EOLSR) that uses Avoidance of Blackhole Attack (ABHA) algorithm to detect and isolate the blackhole node thereby maintaining the reliability of the network.
