Introduction
________________________________________________________
MANET stands for Mobile Ad hoc Network. It is a decentralized autonomous wireless system which consists of free nodes. MANET sometimes called mobile mesh network, is a self configurable wireless network. A MANET consists of mobile nodes, a router with multiple hosts and wireless communication devices. The wireless communication devices are transmitters, receivers and smart antennas. These antennas can be of any kind and nodes can be fixed or mobile. The term node referred to as, which are free to move arbitrarily in every direction. These nodes can be a mobile phone, laptop, personal digital assistance, MP3 player and personal computer. These nodes can be located in cars, ships, airplanes or with people having small electronic devices [18]. Nodes can connect each other randomly and forming arbitrary topologies. Nodes communicate to each other and also forward packets to neighbor nodes as a router. The ability of self configuration of these nodes makes them more suitable for urgently required network connection. For example in disaster hit areas where there is no communication infrastructure. It is greatly desired to have a quick communication infrastructure. MANET is the quick remedy for any disaster situation. MANET is a spontaneous network. It is useful when dealing with wireless devices in which some of the devices are part of the network only for the duration of a communication session. The MANET working group (WG) within the Internet Engineering Task Force (IETF) works specifically on developing IP routing protocols topologies. To improve mobile routing and interface definition standards for use within the Internet protocol suite [18].
Aims and Objectives
There are two basic groups of routing protocols, Proactive MANET protocol (PMP), Reactive MANET Protocol (RMP), and whereas the third one is derived from both of these and called as Hybrid MANET Protocol. The Proactive MANET protocol is generally called table driven protocol and it detects the network layout periodically. It tries to maintain the routing table at every node which is used to detect a most feasible route to the destination from the source with less delay.
Research Question
Our goal in this master thesis is to evaluate the performance of Proactive and Reactive MANET protocols. These protocols have different behaviors with respect to wireless routing perspective. The main problem is to choose the reliable, efficient and correct routing protocol for MANET. The main questions arise for the evaluation of these problems.
First question is which routing protocol provides a better performance in Mobile Ad hoc Networks? This will give the overall performance of each routing protocol. Sec question is what factors influence the performance of these routing protocols? Finally we address the main key differences in these routing protocols. To answer all these questions, we will model some of MANET scenarios with different parameters.
Thesis structure
The thesis is mainly divided into five chapters. Chapter 1 introduces the topic with the detailed discussion of MANET along with the problem statement. Chapter 2 presents the background of our work and types of wireless networks and some part of related work with few examples. Chapter 3 gives full theoretical background and concepts of the ad hoc mobile network routing protocols i.e. reactive MANET protocols and proactive MANET protocols. Chapter 4 is about the performance metrics:
Related work
Extensive research work has been done in the field of MANET routing protocols. Different routing protocols were simulated in different kind of simulators. Here we will discuss different research papers about MANET routing protocols performance. In this thesis work we will simulate three MANET routing protocols in the OPNET modeler 14.5 such as AODV, DSR and OLSR against three different parameters i.e. delay, network load and throughput. The protocols best in the network delay must be the finest in the network throughput. Below we will study now different simulators with different routing protocols and their performance evaluation.
