Due to recent advances in wireless communication technologies, mobile ad hoc networks (MANETs) have become the networks of choice for use in various applications. Unfortunately, this advantage comes with serious security concerns, particularly from a wireless channel prospective, where MANETs may be vulnerable to collaborative wormhole attacks, in particular, packet dropping and message tampering attacks. Recently, two secured routing protocols against these types of attacks (the so-called Highly Secured Approach Method or HSAM and the so-called Securing AODV against Wormhole Attacks in emergency MANET Multimedia Communications or AODV-WADR-AES) were proposed. These schemes are investigated in-depth to identify their weaknesses and a novel secured routing scheme (so-called Timed and Secure Monitoring Implementation against Wormhole Attacks in MANETs or TSMI) is proposed, with the goal to mitigate collaborative wormhole attacks in MANETs while maintaining the performance levels of both the HSAM and AODVWADR- AES schemes. Simulation results are presented to validate the stated goal using various performance metrics.

Mobile Ad hoc Networks (MANET) have been highly vulnerable to attacks due to the dynamic nature of its network infrastructure. Among these attacks, routing attacks have received considerable attention since it could cause the most devastating damage to MANET. Even though there exist several intrusion response techniques to mitigate such critical attacks, existing solutions typically attempt to isolate malicious nodes based on binary or naı¨ve fuzzy response decisions. However, binary responses may result in the unexpected network partition, causing additional damages to the network infrastructure, and naı¨ve fuzzy responses could lead to uncertainty in countering routing attacks in MANET. In this paper, we propose a risk-aware response mechanism to systematically cope with the identified routing attacks. Our risk-aware approach is based on an extended Dempster-Shafer mathematical theory of evidence introducing a notion of importance factors. In addition, our experiments demonstrate the effectiveness of our approach with the consideration of several performance metrics

Secured communication in mobile ad hoc network is a crucial issue due to dynamic nature of the network topology. Due to lack of centralized control, issuing certificates from a centralized certification agent is not possible in ad hoc network. The major problem in providing security services in such infrastructure-less networks is how to manage the cryptographic keys that are needed. In MANET any node may compromise the packet routing functionality by disrupting the route discovery process. These unique characteristics of mobile ad hoc networks such as open network architecture, shared wireless medium, stringent resource constraints and highly dynamic topology cause a number of nontrivial challenges to security design. These challenges make a cause for building multi-fence security solution that achieves both extensive protection and desirable network performance. In particular, the absence of a central authorization facility in an open and distributed communication environment is a major challenge, especially due to the need for cooperative network operation. We propose a novel cluster based security scheme to protect mobile ad hoc network link layer and network layer operations of delivering packet over the multihop wireless channel. The dynamic network topology can be managed efficiently by the proposed cluster based architecture. A well-behaving node becomes a cluster member after the initial trust verification process. The membership validity period of a node depends on how long it has stayed and behaved well. Non-overlapping clusters are created using the dynamic cluster creation algorithm. The cluster construction is fully distributed so efficiency is not degraded by node mobility.
