【 摘 要 】
Problem statement: In Mobile Ad hoc Network (MANET), both the routing layer and theMedium Access Control (MAC) layer are vulnerable to several attacks. There are very few techniquesto detect and isolate the attacks of both these layers simultaneously. In this study, we developed acombined solution for routing and MAC layer attacks. Approach: Our approach, makes use of threetechniques simultaneously which consists of a cumulative frequency based detection technique fordetecting MAC layers attacks, data forwarding behavior based detection technique for detecting packetdrops and message authentication code based technique for packet modification. Results: Ourcombined solution presents a reputation value for detecting the malicious nodes and isolates them fromfurther network participation till its revocation. Our approach periodically checks all nodes, includingthe isolated nodes, at regular time period λ. A node which recovers from its misbehaving condition isrevoked to its normal condition after the time period λ. Conclusion/Recommendations: Bysimulation results, we show that our combined solution provides more security by increased packetdelivery ratio and reduced packet drops. We also shown that our approach has less overhead comparedto the existing technique.
