Cooperative Gray Hole Attack Detection and Prevention Techniques in MANET: Review
Journal Title: International Journal of Science and Research (IJSR) - Year 2015, Vol 4, Issue 1
Abstract
MANET (Mobile Ad Hoc Network) is a type of ad hoc network that can change locations and configure itself, because of moving of nodes. As MANETs are mobile in nature, they use wireless connections to connect various networks without infrastructure or any centralized administration. Open medium, dynamic topology, distributed cooperation are the characteristics of MANET and hence ad hoc networks are open to different types of security attacks. This paper represents a review of different techniques of gray hole attack detection and prevention on AODV routing protocol. All the techniques are having some advantages and disadvantages. Among all of these techniques, the credit based technique gives better performance in terms of end to end delay, throughput and packet delivery ratio. The results can be improved in different cases under various scenarios like pause time, number of nodes and varying speed of nodes.
