The main motivation of an attacker is to convince two far away nodes as neighbor nodes using wormhole attack easily without the knowledge of cryptographic primitives. Thus, it can significantly degrade the performance of Wireless Mesh Networks (WMNs). Secure neighbor discovery is a fundamental requirement of network nodes to ensure secure data communication. An adversary that bypass neighbor di...

The wormhole attack sniffs packets in one point in the network, tunnels them through a wired or wireless link to another point to cause severe influence on the localization process or routing process in the network. In this paper, we analyze the impact of the wormhole attack on the localization in wireless sensor networks and we propose a wormhole attack resistant secure localization scheme. Th...

The open nature of wireless communication channels, lack of infrastructure and fast deployment practices make vulnerable to wide range of routing attacks. One of the most popular attacks is wormhole attack. The transmission time based detection of wormhole attack is proposed and is simulated in Network simulator (ns-2). The detection accuracy of the network is analyzed. The proposed method does...

Wormhole attack is one of the most severe security threats in wireless mesh network that can disrupt majority of routing communications, when strategically placed. At the same time, most of the existing wormhole defence mechanisms are not secure against wormhole attacks that are launched in participation mode. In this paper, we propose WRSR, a wormhole-resistant secure routing algorithm that de...

Today’s Mobile Ad hoc Networks (MANETs) became a popular issue for scientists, and diverse studies have been made to increase the performance of ad hoc networks. In MANET nodes compromise to forward packets for each other communicate beyond their transmission range. The mobile nodes communicate with each other without any infrastructure. As wireless ad-hoc networks lack an infrastructure, they ...

Security issues in mobile adhoc network (MANET) are veiled by various techniques that were introduced in past decade. Owing to decentralized nature of MANET, the security issues cultivates resulting in welcoming various lethal vulnerabilities. Out of all security issues in MANET, wormhole attack is considered one of the most challenging adversarial modules that tremendously affect the communica...

In Mobile Ad hoc Network (MANET) mobile node is responsible for route establishment using wireless link where each node may behave like both as a host and router. MANET encounters number of security threats because of its open entrusted environment, with little security arrangement, security over MANET can be enhance up to some satisfactory level because of its inherent characteristics. Among s...

As mobile ad hoc network applications are deployed, security emerges as a central requirement..Position aided routing protocols can offer a significant performance increase over traditional ad hoc routing protocols. Boundary State Routing (BSR) is a geographic routing protocol which routes the data using the location of the nodes. Geographic routing protocols are known to be particularly suscep...

Wireless sensor networks passes a practical and Economically feasible alternative to manual data association in general and military scenarios, providing a means of surveillance of a region of field and providing warning of any threats. In common wormhole attack, the attacker receives packets in the network, forward them through a wired or wireless association with high-bandwidth low-latency bo...

Wireless Sensor Networks are a Collection of Sensor nodes.Wireless sensor network become so much popular in many fields due to its functionality i.e military, industrial area etc.Security is the important and critical issue in the Wireless networks due to the operating nature of WSNs. This Paper describe the security requirements as WSNs are easily prone more attacks than wired networks. This p...
