In current research self-security management is of high interest. Wireless Ad hoc networks use mobile nodes to enable communication outside wireless communication zone. Attacks on wireless ad hoc network routing protocols disrupt network performance and reliability. In active black hole attacks on wireless networks; malicious nodes advertise the shortest path through the, between source and destination,...
In mobile ad hoc networks the nodes are dynamically changing and they have a fully decentralized topology. Hence, security is hard to achieve due to the dynamic nature of the relationships between the participating nodes as well as the vulnerabilities and limitations of the wireless transmissions medium. We proposed a novel agent based framework to monitor, detect, and isolate misbehaving nodes in...
Traditional routing protocols deployed to provide communication among mobile nodes in wireless ad hoc networks (MANET) assume a trust and collaborating environment inside the network. However, this assumption is not always true and a hostile or unprotected environment can seriously affect the protocol and network performance. In this work two kinds of approaches are applied to a well-known routing...
A mobile ad hoc network is a collection of wireless nodes without any existing network infrastructure or centralized administration. It applies some special routing protocols, e.g. AODV, having the ability to forward the packets in dynamic network topology. The existing routing protocols can be divided into unsecure and secure protocols. They could not address all possible attacks aiming the disruption...
