چکیده
Wireless Sensor Network (WSN) is an emerging technology that shows great promise for various futuristic applications both for mass public and military. These small, low-cost, low-powers, multifunctional sensor nodes can communicate in short distances. There is currently enormous research potential in the field of wireless sensor network security. The major challenge for employing any efficient security scheme in wireless sensor networks is created by the size of sensors, consequently the processing power, memory and type of tasks expected from the sensors. Among various attacks in wireless sensor networks, In a wormhole attack, a pair of attackers forms ‘tunnels’ to transfer the data packets and replays them into the network. This paper provides a survey on wormhole attack and its counter measures and a proposed scheme has been described that can detect and prevent wormhole attack in wireless sensor networks. Keywords— Wireless sensor network; Security; Low latency link; Wormhole attacks; Wireless Sensor Node

Recently, underwater Wireless Sensor Networks (UWSNs) attracted the interest of many researchers and the past three decades have held the rapid progress of underwater acoustic communication. One of the major problems in UWSNs is how to transfer data from the mobile node to the base stations and choosing the optimized route for data transmission. Secure routing in UWSNs is necessary for packet d...
متن کاملA two-phase wormhole attack detection scheme in MANETs
Mobile ad-hoc networks (MANETs) have no fixed infrastructure, so all network operations such as routing and packet forwarding are done by the nodes themselves. However, almost all common existing routing protocols basically focus on performance measures regardless of security issues. Since these protocols consider all nodes to be trustworthy, they are prone to serious security threats. Wormhole...
متن کاملUnauthenticated event detection in wireless sensor networks using sensors co-coverage
Wireless Sensor Networks (WSNs) offer inherent packet redundancy since each point within the network area is covered by more than one sensor node. This phenomenon, which is known as sensors co-coverage, is used in this paper to detect unauthenticated events. Unauthenticated event broadcasting in a WSN imposes network congestion, worsens the packet loss rate, and increases the network energy con...

The Wormhole attack is a critical and challenging security threat for wireless sensor networks (WSNs). Although launching a wormhole attack is a relatively trivial task for the attacker, detecting it from an infected WSN is a tough job, because it can be launched from a compromised legitimate node. In recent years, signal processing methods, like the short term Fourier transform (STFT) and wave...
