Simulation of IPSec Protocol in Ad-Hoc Networks

This paper focuses on securing communication between nodes of ad-hoc networks by applying ipsec. ad-hoc network is a collection of mobile nodes that are dynamically and arbitrarily located in such a manner that the interconnections between nodes are capable of changing on a continual basis. the security factor is one of the main issues as no infrastructure-based solutions are applicable in this area. like in all other networks, the routing is one of the most important parts in this network. ad-hoc on-demand distance vector (aodv) routing protocol is the most popular routing protocol in adhoc networks and it is employed in the simulation model. security in ad-hoc network requires both routing security and data communication security. the proposed ipsec implementation model for both authentication header (ah) and encapsulation security payload (esp) is simulated using the ns-2 simulator and results from the ns-2 simulated environment are compared for both authentication header and encapsulating security payload for secure data communication in ad-hoc networks. the main contribution of this paper is to present ipsec as a good solution for ad-hoc network security problems.
