LDAC: A localized and decentralized algorithm for efficiently countering wormholes in mobile wireless networks
作者：
Highlights：
• We consider the case of wormholes in which an adversary uses secret links to establish false neighbor relationships between distant nodes.
• LDAC is localized and works by looking for simple evidence that no attack is taking place, using only connectivity information.
• Our approach also accounts for mobile wireless networks with dynamic links and high degree of association and de-association between the nodes.
• LDAC always prevents the establishment of wormholes, while simulations show that the rate of false positives is kept very small.
• It is very easy to be implemented in practice, even in resource constrained devices such as sensor nodes.
