Experimental security analysis for SAODV vs SZRP in Ad-Hoc Networks

Abstract

Ad-hoc network, due to its fundamental characteristics like open environment operation, random topology and capability limitation, is mostly at risk from secuirity point of view. There may be malicious threats during data transmission from one user to another user, which leads to affect the system performance and causing insecurity in data transmission. Many routing protocols consider these secuirity issues as major point of consideration and hence try to overcome the secuirity threats in ad-hoc networks. In this article, a scenario is set up for simulation to evaluate the performance and security issue of two secure routing protocols that are secure ad-hoc on demand vector (SAODV) and secure zone routing protocol (SZRP). In this paper, simulation has been done for number of times with different values of pause time ranging from 0 to 800 seconds for both protocols. And finally, simulation has been done for malicious environment with different numbers of malicious nodes ranging from 2 to 18 nodes for both protocols. Our analysis has been done under two performance metrics-one is packet delivery ratio and second is end to end delay. Experimental results have been obtained using NS-2 (version 2.34) mainly. We have prepared excel graphs from. Tr (trace) files. Based on experimental outcomes paper concluded, that SZRP outperforms SAODV for real time applications. © 2014 IEEE.
