Analysis of Different Propagation Model for IPSec-LANMAR Routing Protocol to Secure Network Layer for MANET in Emergency Area Environment
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.
