  6. 5. Security and Performance Analysis of Topology-Based Intrusion Detection System in Ad Hoc Networks

    University essay from Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

    Author : UMUNNA CHRISTIAN CHEZZ CHETACHI; [2009]
    Keywords : Ad-hoc networks; cluster topology; Intrusion detection system; jammer attack Security;

    Abstract : As Wireless ad-hoc Networks are becoming an increasingly emerging technology taking a centre stage in exciting research areas which has attracted many research attentions in communication systems, the need for efficient intrusion detection techniques to enhance network security and privacy has gained significant prominence. Intrusion detection systems(IDS) in ad- hoc networks provides an effective method to improve the security, energy efficiency of transmission nodes allowing better spatial reuse of the wireless channel and control over network resources in order to optimize node security and the transmit power thereby maintaining network connectivity.
