We analyze a new wormhole routing scheme, which we call the wormhole deflection with virtual channels (abbreviated WDVC) scheme, that combines wormhole routing with virtual channels and deflection routing to provide efficient lossless communication. We use new analytical models to analyze the performance of the WDVC scheme for the Manhattan Street (MS) network topology. In particular, we examin...

The switching scheme of a point-to-point network determines how packets flow through each node, and is a primary element in determining the networks performance. In this paper, we present and evaluate a new switching scheme called hybrid switching. Hybrid switching dynamically combines both virtual cut-through and wormhole switching to provide higher achievable throughput than wormhole alone, w...

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...

Traversal time and hop count analysis (TTHCA) is a recent wormhole detection algorithm for mobile ad hoc networks (MANET) which provides enhanced detection performance against all wormhole attack variants and network types. TTHCA involves each node measuring the processing time of routing packets during the route discovery process and then delivering the measurements to the source node. In a pa...

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...

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 ...

As demand increases for ubiquitous network facilities, infrastructure-less and self-configuring systems like Mobile Ad hoc Networks (MANET) are gaining popularity. MANET routing security however, is one of the most significant challenges to wide scale adoption, with wormhole attacks being an especially severe MANET routing threat. This is because wormholes are able to disrupt a major component ...

As Mobile Ad-hoc network is infrastructure less network in which every node can take part in data transmission and reception process. Various kinds of attacks have been arises in the network during transmission, which affects on the performance of the network. Wormhole attack is one attack from them which is created by collaborative attackers. Different techniques have developed to detect & pre...

Network security is an important criteria for wired and wireless communication. The advancement in wireless technologies and the high availability of wireless equipment in everyday devices is a factor in the success of infrastructure-less networks. MANETs are becoming more and more common due to their ease of deployment. The high availability of such networks and the lack in security measures o...

The nature of wireless ad hoc and sensor networks make them very attractive to attackers. One of the most popular and serious attack in wireless ad hoc networks is wormhole attacks 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 mec...
