A Review of Blackhole Attack in Mobile Adhoc Network

Mobile ad hoc network (MANET) is used in a wide range of application from civilian usage to military battlefield communications. Using multi-hop communication model, a source node can directly communicate with the destination node without infrastructure. Unfortunately, this feature causes the network vulnerable to various attacks. Security preventions implemented in the traditional wired network are unsuitable for MANET. This paper studies several types of attacks, and then discusses one of the most severe attack in the network, blackhole attack. Furthermore, recent efforts for preventing the blackhole attack are comprehensively discussed. Study of literature indicates that the prevention of the blackhole attack can be categorized into three groups, i.e., Protection based on Cryptography, Protocol Modification, and Intrusion Detection and Counter Measure.
