Detection and mitigation of node replication with pulse delay attacks in wireless sensor network

A Localization Technique in Wireless Sensor Network based on Angle of Arrival

“…We assume that all sensor nodes are capable to detect angle of incident signal from neighboring sensor nodes. This approach is helpful to achieve much better localization coverage in comparison to last existing approach in [10]. This type of efforts can increase security of wireless sensor networks.…”

“…Where as in [10] server recognizes the pulse-delay attack [11] and malicious node in WSN. In routing algorithm [10,12] is used to overcome the node replication attack and pulse delay attack.…”

“…In routing algorithm [10,12] is used to overcome the node replication attack and pulse delay attack. This algorithm detects the replicated node and finds the message delay in transmission between two nodes.…”

“…In the routing algorithm [10] all types of attacks in wireless sensor network are discussed with their effects. the proposed algorithm [8] isto overcome the node replication attack.…”

“…The algorithm for node replication attack [10] typically focus on the detection of replicated based on the arrival time of sensor node in the network but in this paper we assign a position based on angle of arrival of localization for all sensor nodes. It explains that each and every sensor node has its own place in the network so any mobile replicated node will not be able to communicate with any sensor node and interfere in the transmission of sensor nodes.…”
