Abstract
Byzantine attacks signify a risk to Mobile Ad Hoc Networks (MANETs). One of the efficient routing protocols used to mitigate such attacks in MANETs is the On-Demand Secure Byzantine Routing protocol (ODSBR). In this paper, we present the Modified ODSBR (MODSBR) where several enhancements for the performance and security of ODSBR are implemented. The first of these enhancements is enabling route caching in an elegant way that causes a notable decrease
in the routing overhead. The central clustered link weight management (CLWM) is a secure technique utilized by MODSBR to detect malicious nodes through a set of management nodes (MN). The effect of the proposed enhancements is evaluated with respect to different types of Byzantine attacks. Simulation experiments show that MODSBR outperforms ODSBR by an average 23% decrease in routing overhead and a 10 % increase in the delivery ratio for different mobility values.
