Critical Review of Techniques for Detection and Mitigation of Co-operative Blackhole Attack in MANET

Abstract

© 2018 SERSC Australia. Mobile Ad-hoc NETwork can be stated as a self configuring network that is infrastructure-less and communication happens in multi-hop manner. This dynamic nature of MANET and lack of infrastructure makes it vulnerable to many types of attacks; both routing and security. Out of all these attacks a variation of packet drop attack known as co-operative Blackhole attack proves to be a bottleneck in MANET. In this paper, we have reviewed many existing solutions that are useful in mitigation and detection of cooperative Blackhole attack. Co-operative Blackhole involves two or more malicious nodes working together to perform packet drop. We have provided a detail on these mechanisms involving the methodology and algorithms followed in the mechanisms, simulation and their conclusive result in brief and their critical review for drawbacks and advantages. A comparison is drawn and finally, the areas are identified in the field of mitigation of cooperative Blackhole attack on which the future research should be focussed.
