  • 摘要: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. In this work, 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 nodes 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.
