Mobile ad-hoc network (MANET) is an independent system linked by mobile nodes with wireless connections. Because of unavailability of infrastructure, MANET is utilized in several applications i.e. business applications, battlefield and remote regions. As, communication among the nodes is by the insecure wireless connection, security is very significant issue for this kind of networks. MANET is susceptible to attacks i.e. Gray hole attack, Black hole attack, Sybil attack, wormhole attack and Route table modification attack. Black hole attack has critical effect on delivery ratio and routing of packets. To secure from Black hole attack, a techniques i.e. intrusion detection system, trust based routing, Data Routing Information table (DR!) and sequence number comparison has been suggested. Trust based On Demand routing method identifies and reduces the risks by harmful node in the route. This paper offers a review of preventing and detecting Black hole attack utilizing trust management method in MANET.
