Abstract
Ad-hoc Wireless Sensor Networks usage spreading rapidly due to their flexibility to provide communication in unattended and hostile environment like military target tracking and weather prediction, without fixed infrastructure to provide communication. In Ad-hoc Wireless Sensor Networks nodes are communicate while moving. Since lack of physical security, it easily prone to security attacks. The network suffers from various attacks such as wormhole, black hole, and selective forwarding attack. Selective forwarding attack is a severe threat enables a compromised node behaves like normal node and may drops packets selectively. It deteriorates the performance of networks and integrity of information. Due to resource limitations of sensor nodes, it is not feasible to use conventional security solutions, which requires complex computations and more memory. Due to nodes mobility, it is a challenging task to detect selective forwarding attacks in Ad-hoc Wireless Sensor Networks. In this paper, we discuss some of the authentication strategies and detection techniques to defend and defeat against selective forwarding attacks.
