Reliability Modeling of a Cluster Based Distributed Mobile Ad-hoc Network

Abstract

Modelling of a mobile ad-hoc network is a simplest way to represent real life networks for reliability and performance analysis. In this paper, an effort is made to develop a model of ad-hoc network cluster for evaluation of reliability. This model is based on Continuous-Time Markov Chain (CTMC). A mobile ad-hoc network model is especially useful to understand the practical implications and limitations of real world problems. A Cluster based approach is desirable for a large-scale multi-hop Mobile Ad-hoc Networks (MANET) in many future applications. The network models, mobility models and simulators for MANETs are reviewed by identifying their current limitations and future trends. Markov model is being used to solve dynamic system such as MANET. It is a mathematical system consisting of finite number of possible states that undergoes transition from one state to another state. In this paper, we also discuss how Markov�s model is used for estimating the reliability of a distributed ad-hoc network cluster using available tools. This paper also uses simulation scenarios and discusses simulation model design for reliability and performance evaluation of Ad-Hoc network.
