A Secure Intrusion-Detection System Using Enhanced Adaptive Acknowledgement for MANETS

Mobile ad hoc Networks (shortly called as MANETs) are of increasing interest for various sets of applications. Instead of using any centralized infrastructure, nodes in MANET cooperate with one another to provide networking during their movements. Such capability is essential for some special scenarios like battlefield or emergency field work wherever preexisting or centralized communication infrastructures are not offered. MANET on the battlefield will offer various services to support different missions such as enemy situation, battlefield map, etc. Such applications place increasing demands on reliable transport and persistent sessions. EAACK is capable of detecting malicious nodes despite the existence of false scheme report and compared it against alternative widespread mechanisms in many situations through simulation. The results will demonstrate positive performances against Watchdog, TWOACK and AACK within the cases of receiver collision, restricted transmission power and false misbehavior report, packet delivery Ratio. IDDSA demonstrates higher malicious- behavior-detection rates in certain circumstances while does not greatly have an effect on the network performances.
