A Survey on Detection and Prevention of Black Hole Attack in MANET

Abstract Mobile adhoc network (MANET) is a collection of wireless mobile nodes and use the wireless connections to connect to the various networks. It doesn’t require any base station. Mantes are prone to various kinds of security attacks as black hole, worm hole, gray hole and Man in middle attack. Possible and common attack in adhoc network is black hole attack. In black hole attack malicious node provides fake routing information by advertising itself as having shortest path to destination and then drops the packets later. In this work the survey is considered on the various methods to detect and prevent black hole attack in MANET.
