Wormhole Attack Detection in Wireless Sensor Networks
The nature of wireless ad hoc and sensor networks make them very attractive to attackers. One of the most popular and serious attacks in wireless ad hoc networks is wormhole attack and most proposed protocols to defend against this attack used positioning devices, synchronized clocks, or directional antennas. This paper analyzes the nature of wormhole attack and existing methods of defending me...
متن کاملMachine Learning Techniques for Wormhole Attack Detection Techniques in Wireless Sensor Networks
The wormhole attack in Wireless sensor networks (WSNs) decreases the network performance by dropping the No. of Packets. Many techniques have been proposed to so far reduce the impact of the wormhole attack by detecting and preventing it. But, related work indicates that no technique is perfect for every kind of circumstances of WSNs. Among the existing techniques, Watchdog technique has better...
متن کاملRouting Hole Handling Techniques for Wireless Sensor Networks: A Review
A Wireless Sensor Network consists of several tiny devices which have the capability to sense and compute the environmental phenomenon. These sensor nodes are deployed in remote areas without any physical protections. A Wireless Sensor Network can have various types of anomalies due to some random deployment of nodes, obstruction and physical destructions. These anomalies can diminish the sensi...
متن کاملA Wireless Sensor Networks Test-bed for the Wormhole Attack
In some applications, wireless sensor devices must be secured, especially when the captured information is valuable and sensitive. The wormhole attack is a significant type of security attack that can damage wireless sensor networks if they go undetected. It occurs when the attacker records packets at one point of the network, and then passes them into a different node. This node then injects t...
متن کاملAn efficient wormhole attack detection method in wireless sensor networks
Wireless sensor networks are now widely used in many areas, such as military, environmental, health and commercial applications. In these environments, security issues are extremely important since a successful attack can cause great damage, even threatening human life. However, due to the open nature of wireless communication, WSNs are liable to be threatened by various attacks, especially des...
