The wireless sensor networks are prone to various attacks; this is primarily due to the fact that these networks once deployed are left unattended. So any attacker with the intention of stealing the information from the network can compromise any node and gain access to the data being propagated in the network. Various attacks possible are black hole attack, wormhole attack, Sybil attack, clone...

Due to dynamic topology and non-wired infrastructure of Wireless Sensor Networks (WSN), they are prone to attacks. Wormhole attack is one of the most popular and serious attack in WSNs. In Wormhole attack two or more malicious nodes makes a covert channel which attracts the traffic towards itself by depicting a low latency link and then start dropping and replaying packets in the multi-path rou...

Wormhole attack is a type of replay attack in wireless networks that has serious consequences and is hard to defend against. This is because the attacker does not need to modify packets or compromise wireless nodes. This paper introduces Wormeros, a new framework to detect wormhole attacks in wireless networks. The framework contains two phases namely suspicion and confirmation. Our solution do...

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...

In ad hoc networks, malicious nodes can carry wormhole attacks to fabricate a false scenario on neighbour relations among mobile nodes. The attacks threaten the safety of ad hoc routing protocols and some security enhancements. In the wormhole attack, an attacker records packets (or bits) at one location in the network, tunnels them (possibly selectively) to another location, and retransmits th...

Wireless Sensor Network platforms are less expensive and more powerful having tiny electronic devices called Motes (sensor nodes). Wireless sensor networks enhance its popularity in military and health centric research areas; now it is also popular in industrial area. This paper describes the security requirements as WSNs are easily prone to more attacks than wired networks. This paper studies ...

Wireless networking relies on a fundamental building block, neighbor discovery (ND). However, the nature of wireless communications makes attacks against ND easy: an adversary can simply replay or relay (wormhole) packets across the network and mislead disconnected nodes they communicate directly. Such attacks can compromise the overlying protocols and applications. Proposals in the literature ...

As mobile ad hoc network applications are deployed, security emerges as a central requirement. In this paper, we introduce the wormhole attack, a severe attack against ad hoc routing protocols that is particularly challenging to defend against. We show how an attacker can use the wormhole attack to cripple a range of ad hoc network routing protocols. In the wormhole attack, an attacker records ...

Security emerges as a central requirementas mobile ad hoc network applications are deployed. In this paper, we introduce the wormhole attack, a severe attack in ad hoc networks that is particularly challenging to defend against. Wormhole attacks enable an attacker with limited resources and no cryptographic material to wreak havoc on wireless networks. It is possible even if the attacker has no...
