Integrated Context-Based Mitigation Framework for Enforcing Security against Rendezvous Point Attack in MANETs

Reliable communication in ad hoc networks necessitates mobile nodes to synchronize among themselves for cooperation. The cooperation in ad hoc networks is enforced through the implementation of encryption algorithms and intrusion detection systems. Most of the intrusion detection and encryption algorithms are not effective enough to address the extent to which a participative mobile node may trust other interacting mobile nodes for data forwarding. The existing mitigation frameworks consider packet forwarding capability as the single parameter for calculating trust values which cannot be appropriate for computing the accurate trust factor as reliable nodes are highly impacted by data rate, throughput, delay and energy consumption. An Integrated Context-based Mitigation Framework (ICMF) is proposed for facilitating effective mitigation of rendezvous point misbehavior and for enhancing the performance of the network. This proposed ICMF framework facilitates rendezvous point misbehavior detection by determining Grey theory Inspired Discriminating Factor (GTIDF) that is contextually derived from multiple factors including data rate, throughput, delay and energy consumptions using the benefits of the Grey theory. From the simulation results of the proposed ICMF framework, improved root node attackers survivability rate and root node attackers categorization rate are inferred when compared to the benchmarked baseline mitigation frameworks.
