MANET Study And Analysis For Secured Data Communication Using Soft Computing Techniques

Abstract

The communication system will conjoin both infrastructure wireless networks and the newlineinfrastructure less wireless networks, commonly known as Mobile Ad Hoc Networks newline(MANETs). Each node in an Ad hoc network acts both as a host and a router and newlinetherefore is willing to forward packets for other nodes; a routing protocol is required newlinefor this purpose. MANETs along with its special features has several challenges and newlineissues those need to be considered. Routing in MANETs is one of such issue. newlineThe Ad Hoc network routing protocols can be broadly classified into two classes: newlineProactive routing protocols (or table-driven routing protocols) and Reactive routing newlineprotocols (or On-demand routing protocols). The primary objective of this thesis is to newlinedo comparative investigation of the performance of routing protocols in a simulated newlineenvironment against varying network parameters and traffic to provide a qualitative newlineassessment of applicability of protocols in different scenarios. The performance newlinedifferentials are analyzed using varying node mobility, network size, maximum speed, newlinetraffic load and data rate. The evaluations are done by means of simulations using NS- newline2 network simulator. newlineThis thesis begins with a brief introduction about the routing, routing algorithms, newlineclassification of routing protocols. A brief introduction of the Mobile Ad hoc network newlineis provided concentrating mainly on the characteristics, applications and routing issues newlinein MANETs. The problem statement has also been identified. newlineIn the first chapter, I have discussed some background information about the Mobile newlinead hoc networks (MANETS) are self-created and self-organized by a collection of newlinemobile nodes, interconnected by multi-hop wireless paths in a strictly peer to peer newlinefashion. DSR (Dynamic Source Routing) is an on-demand routing protocol for newlinewireless ad hoc networks that floods route requests when the route is needed. Route newlinecaches in intermediate mobile node on DSR are used to reduce flooding of route newlinerequests, but with the increase in network size, node mobi
