Chapter 1 Introduction

In recent decade, the usage as well as popularity of mobile communication has widely increased all around the world. So the devices are becoming more and more compact, the standby time of the batteries are being improved for a longer period and communication protocols are getting more strong and providing more sturdy throughput. Now a days, Wireless Technology has taken over the Wire Communication, thus giving the facility of mobility to the users.

The main idea of mobile ad-hoc networking is to support strong and efficient operation in mobile wireless networks, by introducing the routing functionality into mobile nodes. These kinds of networks can have dynamic, sometimes rapidly-changing, multi-hop topologies which are likely composed of relatively bandwidth constrained wireless links.
Implementation Work:
The work this thesis covers is the modification of the Routing Protocol that is already implemented for mobile wireless networks. The entire implementation has been rewritten as before and in some aspects added. It is now implemented to comply with the RFC describing the protocol and to be as extensible as possible.

In the thesis the Optimized Link State Routing Protocol is implemented and the extension on the routing protocol is also the part of my thesis.

As the space is limited so the background of the technical aspects will not be included in every part of this thesis. I expect that the reader has some basic knowledge of mobile ad hoc networks, UDP/TCP IP networking and C programming.

1.2 Chapter overview:

Chapter 1 is the general Introduction and in Chapter 2, I have given the introduction to Mobile Ad-hoc Networks some basics of wireless data-communication are also introduced in it. I have also included the two routing protocol that are proposed by (IETF). Chapter 3 is for the Core-Functionality of the OLSR. The process of implementing and simulations of OLSR protocol is described in chapter 4. Our proposed model and its extension to OLSR are presented in chapter 5.

Chapter 2 Mobile AD-HOC Networks

The basis on which much of the Wireless Technology works, is known as “Point to Point Communication”. Popular solutions like Global System for Mobile communication (GSM) and Wireless Local Area Network (WLAN), use the same approach in which ‘mobile node’ is used that communicates with centralized Access point. Centralization for configuration and operation is required for these types of networks. Multi-Hop approach is opposite to the model that is mentioned above. In Multi-hop if the end point is out of direction, the nodes can communicate with each other by utilizing the other node as relays of traffic. Multiple nodes are may be involved between the communication of two nodes. Sometimes it happens that a node is not been accessed directly. Data or control packets can be sent from one node to another node through several nodes. These types of networks are called mobile ad hoc networks.

The multi-hop model is used by Mobile ad-hoc networks (MANET). Mobile ad-hoc networks are infrastructure less where the communication between two nodes is accomplished through wireless media. Node mobility is freely allowed as there is no structured media, which translates into a constantly changing network topology.
