Empirical Performance Evaluation of Reactive Routing Protocols for Wireless Ad hoc Networks in Adversarial Environment

Researchers have already shown the way, how to improve and compare the existing MANET routing protocols that help us to understand the basic feature and functionality of the various routing protocols. However, while these routing protocols have been proposed from different research groups in the literature, which shows the existing routing protocols, are not consistent to common framework to evaluate its performance. Moreover, these protocols are vulnerable to many collaborative attacks, due to its cooperative nature of routing algorithms. Hence, it is difficult for one to choose a proper routing protocol for a given application; therefore, we initially study and review to compare the different existing routing protocols in adversarial environment with varying traffic and mobility simulation scenarios. This paper addresses the comparison of various reactive routing protocols in adversarial environment. To achieve this, we had investigated with widely used NS-2 simulators for fair comparisons of different routing protocols. Furthermore, we also develop a collaborative adversary model for these existing routing protocols that can interfere with communications to subvert the normal operation of the network. Specifically, Our extensive simulation results shows the relative quantitative analysis for comparing the performance of reactive routing protocols such as AODV, DSR under adversarial environments with varying traffic and mobility simulation scenarios. Moreover, the performance of these protocols is measured with the various metrics such as throughput, end-to-end delay, packet delivery ratio, and routing overhead.
