Ad hoc networks can be rapidly deployed and reconfigured. Hence, they are very appealing as they can be tailored to lots of applications. Due to their features they are vulnerable to attacks. A particularly severe security attack, called the wormhole attack, has been introduced in the context of ad-hoc networks. During the attack a malicious node captures packets from one location in the network,...
Building trust has been recognized as a new security approach for wireless distributed networks. In the paper, we try to provide a completely new view by building trust territory in ad hoc networks. The concept of trust territory is addressed and the approach to build trust territory is also discussed. A trust territory contains all nodes trusted by the node. It is considered secure to communicate...
Trust is one of the basic assumptions that we use in every day life. In ad hoc networks, routing protocols implement trust implicitly between the nodes of the network. Unfortunately, the implicit trust relations are not used by nodes whereas the attacks on ad hoc routing protocols precisely lead to the violation of at least one of these trust relations.In this paper, we demonstrate that a node can...
Secure and efficient communication among a set of mobile node is one of the most important research subjects in ad hoc wireless networks. Due to the resource scarcity in ad hoc networks, traditional key management protocol cannot be effectively applied to such decentralized networks. After study different strategies, in this paper the trust evaluation based clustering technique is employed to propose...
Mobile ad hoc network (MANET) faces serious security threat due to lack of consideration of security in design and inherent weaknesses. Anomaly detection techniques as well as preventive measures are in urgent need to protect ad hoc network. We propose an innovative anomaly detection technique based on temporal analysis of routing activities. Our approach uses data mining techniques to discover the...
