Threshold based scheme for isolation of Wormhole Attack in WSN
Wireless Sensor Network, WSN Security, Wormhole Attack, Availability.
Out of many attacks in wireless sensor network, the wormhole attack is pretty dangerous one as it is launched using two pairs of malicious nodes with create a tunnel by skipping few nodes in between source and destination node. The existing scheme considers the wormhole attacks when there are no intermediate nodes present between destinations. This technique is suitable for scenarios where the path length between source and destination is two hops only. This scheme cannot be used for networks with layer hops between source and destination node. In this research work, we are proposing a threshold based scheme for the detection and isolation of malicious nodes in the network. The malicious nodes are responsible to trigger wormhole attack in the network. As per hop delay is already calculated in the network and node which is increasing the per hop delay than defined value is detected as the malicious node. When the malicious node is detected from the network then the source node will send alert message to each node in the network. When the node receives the alert message, it will remove the malicious node from the path. The technique is efficient in terms of complexity and also various congestion values are included for the detection of malicious nodes. In this phase, the malicious nodes get isolated from the network with the approach of multipath routing. The sensor nodes which increase per hop delay is detected as the malicious nodes. The proposed technique is implemented in NS2 and simulation results shows that proposed technique performs well as compared to other techniques.
