A Hop-Count Analysis Scheme for Avoiding Wormhole Attacks in MANET
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-...
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 ...
متن کاملA Study on Wormhole Attacks in MANET
An Ad-hoc network is a self-organized network, without a central coordinator, and which frequently changes its topology. In this paper, we have analyzed the performance of Mobile Ad-hoc Networks (MANET) under wormhole attack. Multiple QoS parameters have been considered here such as throughput, delay, packet delivery ratio, node energy and node density. The NS2 network simulator has been used a...
متن کاملAvoiding Wormhole Attack in MANET using Statistical Analysis Approach
MANET is a collection of mobile hosts with wireless network interfaces that form a temporary network without any fixed infrastructure or centralized administration. MANET is infrastructure-less, lack of centralized monitoring and dynamic changing network topology. MANET is highly vulnerable to attack due to open error prone shared wireless medium. In this paper, we proposed an algorithm for avo...
متن کاملDetecting Wormhole Attacks in Wireless Sensor Networks Using Hop Count Analysis
The wormhole attack is a severe threat to wireless sensor networks. Most existing countermeasures for detecting and locating wormhole links either require extra hardware or are too complex for the inherently capability-constrained sensor nodes. Actually, wormhole links can enormously change the original sensor network topology. In this paper, we introduce the HCA4DW mechanism for detecting and ...
