A Novel Approach for the Reliability Analysis of Flow Networks, Manets and Vanets

Abstract

This dissertation will review the existing methods for the analysis of network reliability. Additionally, it reviews the literature in the areas related to Adhoc networking, wireless networking and reliability optimization. An extensive review has been done to identify the current drawbacks in analyzing the Network reliability. Moreover, this research presents suitable methods and potential results to solve many real life problems. The main objective of this dissertation is on executing reliability of MSFN and MIN. This manuscript demonstrates an inclusive approach for analyzing certain reliability models, discussions on real life application of stochastic models that diverse the areas like Stochastic Flow Networks (SFN), Mobile Adhoc Networks (MANET), and Vehicular Adhoc Networks (VANET). The ultimate aim is to offer a Mathematical model to realize a highly reliable network that still conforms to other constraints like time and cost towards the system's development. Organization of this dissertation is as follows. Introduction to this research field is done in Chapter 1. Chapter 2 models an algorithm to pertain the reliability evaluation of a MSFN. The problem accounted in this chapter is on executing the reliability of a MSS using Minimal path (MP) algorithm. The problem modelled here analyse the reliability of the system while sending d amount of data through m number of MPs simultaneously under both time and budget constraints. Chapter 3 expounds the assessment of MANET reliability using the Universal Generating Function Technique (UGFT) subject to the constraints minimum cost and time . The different physical nature and different types of elements interaction of the MANET are modelled by constructing UGFs, which are used to describe the probability distributions of successful delivery between source and target. The communication within the network is addressed by the path UGF. . Chapter 4 focuses the assessment of MANET by considering the Cluster Head Gateway Routing (CHGR) protocol. Chapter 5 discusses the novelty algorithm for performance assessment of a MANET using weighted Universal Generating Function Technique (WUGFT). This work introduces a novelty approach based on Weighted Universal Generating Function which will reduce the computation burden in achieving the reliability of a MANET. The emphasis in Chapter 6 is on enhancing the MANET reliability using Reliable Cluster Forming Protocol (RCPF). Cluster formation and execution of link reliability is formulated using a novelty algorithm based on UGFT. A simulation environment using Network Simulator-2 (NS-2) has also been done. Chapter 7 aims to execute the VANET reliability using the UGFT. VANET is a subset of MANET where the moving vehicles are considered as nodes to make a communication between vehicles. The primary goal of VANET is to disseminate road safety messages including vehicles current speed, location, traffic alert messages, drivers behaviours etc. in an efficient manner. Chapter 8 is intended to provide a reliable path discovery in vehicular adhoc network using RCPF. This chapter integrates the performance of RCFP in VANET domain. It implements RCFP in five phases namely identifying neighbouring nodes, calculation of combined weight, cluster formation, achieving the connectivity among clusters and routing.
