Abstract
Mobile ad hoc networks (MANETs) consist of a collection of
wireless mobile nodes, which dynamically exchange data among
themselves without the reliance of a fixed base station. It have
potential use in a wide variety of disparate situations such as
responses to hurricane, tsunami, earthquake, emergency relief,
terrorism and military operations. Inthiswork, investigations on
the behavior of IPSec-LANMAR routing protocol with propagation
models that take into account two main characteristics of the
wireless channel - path loss and shadowing is presented.
The choice of radio propagation models with IPSec-LANMAR
also has a strong impact on the performance of a protocol
because the propagation model determines the number of
lodes within one collision domain, an important input for
contention and interference. This, in turn, has a direct effect
on a node’s ability to transmit a packet to another node and
it provide security services for both routing information and
data message at network layer. The simulation result shows
that Free space propagation model with IPSec-LANMAR routing
protocol outperforms compared to Two ray propagation model
and Shadowing model in emergency area environment and
the experiments are carried out using the simulator Qualnet
version 5 also the performance of propagation models with
IPSec-LANMAR for MANETs is compared based on different
parameter metrics.
