Abstract: Mobile Adhoc network (MANET) is a wireless network. It is collection of different mobile nodes. The basic characteristics of MANET are dynamic topology and lack of centralization. Due to these characteristics MANETs are vulnerable to many attacks. Black hole attack is one of the attacks, which is performed on network layer. In black hole attack, malicious nodes disrupt transmission of data by sending false routing information. There are two types of black hole 5attacks. Single and collaborative. Single black hole attack has one malicious node, which can act as node with highest sequence number. Source node will follow malicious node’s path by assuming correct route. Collaborative black hole attack has more than one malicious node. In this attack, one malicious node receives packet and send to another malicious node. Detection and prevention of black hole attack is very challenging task. In this paper, our propose solution EBAODV (Enhance Black hole AODV) is presented. Many researchers have invented detection and prevention schemes of black hole attack. The comparative study of many researchers is also presented in this paper. Our solution EBAODV, focus on leader nodes. Leader nodes are used to detect black hole attack and prevent it by sending block table of malicious nodes.
