A Hop-Count Analysis Scheme for Avoiding Wormhole Attacks in MANET
نویسندگان
چکیده
MANET, due to the nature of wireless transmission, has more security issues compared to wired environments. A specific type of attack, the Wormhole attack does not require exploiting any nodes in the network and can interfere with the route establishment process. Instead of detecting wormholes from the role of administrators as in previous methods, we implement a new protocol, MHA, using a hop-count analysis from the viewpoint of users without any special environment assumptions. We also discuss previous works which require the role of administrator and their reliance on impractical assumptions, thus showing the advantages of MHA.

Mobile Ad hoc Networks (MANET) are vulnerable to both active and passive attacks. The wormhole attack is one of the most severe security attacks in wireless ad hoc networks, an attack that can be mounted on a wide range of wireless network protocols without compromising any cryptographic quantity or network node. In Wormhole attacks, one malicious node tunnels packets from its location to the ...
متن کاملA New MANET Wormhole Detection Algorithm Based on Traversal Time and Hop Count Analysis
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 ...

Wormhole attack is considered one of the most threatening security attacks for mobile ad hoc networks (MANET). In a wormhole attack, a tunnel is setup in advance between two colluders. The colluders record packets at one location and forward them through the tunnel to another location in the network. Depending on whether or not the colluders are participating in the network functions, the wormh...

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...
متن کاملA Simple Algorithm for Detection and Removal of Wormhole Attacks for Secure Routing In Ad Hoc Wireless Networks
The infrastructure of a Mobile Ad hoc Network (MANET) has no routers for routing, and all nodes must share the same routing protocol to assist each other when transmitting messages. However, almost all common routing protocols at present consider performance as first priority, and have little defense capability against the malicious nodes. Many researches have proposed various protocols of high...
