Simulation of Cryptographic Algorithms in IPSEC on AD-HOC Networks
This paper focuses on secure data communication between nodes in AdHoc networks by employing
IPSec(Internet Protocol Security). In wireless communication, adhoc network is a new paradigm since which is used for
highly sensitive and emergency operations. Adhoc network is considered a number of mobile nodes that are connected
through wireless interfaces and moves arbitrarily. Ensuring security is one of the main issues due to its infrastructure less
solutions. This research aims for IPSec protocol that provides security for an ad-hoc networking in a various applications.
IPSec incorporates security model i.e. AES (Advanced Encryption Standard) into its framework.In this work, we consider
the problem of incorporating security mechanisms to securing data communication for adhoc networks. We look at AODV
routing protocol (Ad-Hoc On-Demand Distance Vector) in detail and it is used for secure routing. Simulation of IPSec
protocol is simulated using NS-2 simulator. Results from NS-3 simulator is compared with AH, ESP, and AES in terms of
Quality of Service parameters throughput, average processing time and average end-to-end delay.
