RISM -- Reputation Based Intrusion Detection System for Mobile Ad hoc Networks
This addresses security vulnerabilities in mobile ad hoc networks, which are critical for applications like military or disaster response, but it is incremental as it builds on existing routing protocols.
The paper tackles intrusion detection in mobile ad hoc networks by combining an IDS with a routing protocol, using a reputation-based approach inspired by human behavior, and it outperforms normal DSR with up to 50% malicious nodes, showing improvements in packet delivery ratio and routing overhead.
This paper proposes a combination of an Intrusion Detection System with a routing protocol to strengthen the defense of a Mobile Ad hoc Network. Our system is Socially Inspired, since we use the new paradigm of Reputation inherited from human behavior. The proposed IDS also has a unique characteristic of being Semi-distributed, since it neither distributes its Observation results globally nor keeps them entirely locally; however, managing to communicate this vital information without accretion of the network traffic. This innovative approach also avoids void assumptions and complex calculations for calculating and maintaining trust values used to estimate the reliability of other nodes observations. A robust Path Manager and Monitor system and Redemption and Fading concepts are other salient features of this design. The design has shown to outperform normal DSR in terms of Packet Delivery Ratio and Routing Overhead even when up to half of nodes in the network behave as malicious.
