Mitigation of Black Hole and Grey Hole Attack In Mobile Ad hoc Networks
Amanpreet Kaur, Manjot Kaur Sidhu · 2014
Wireless networks are gaining popularity to its peak today. Mobile Ad hoc Networks called MANETs are self-configuring wireless networks and it is without any centralized control made by mobile nodes. Nodes can act as both routers and hosts. The dynamic topology of MANETs allows nodes to join and leave the network at any point of time. So, it is vulnerable to various kinds of attacks like Active attack, Passive attack, Internal attack, External attack, Black hole and grey hole attack. Previouswork is done on security issues in MANET were based on reactive routing protocol example: Ad-Hoc On Demand Distance Vector (AODV). Various kinds of attacks were studied earlier, and their effects were elaborated by stating how these attacks disrupt the performance of MANET. In this paper, we present a review on number of techniques that helps to mitigate black hole and grey hole attack that effect the performance of MANET.
