Ad Hoc Network Essay
ABSTRACT
Ad-hoc networks have opened a new dimension in wireless networks. It allows wireless nodes to communicate in absence of centralized support. It doesn‟t always follow any fixed infrastructure due to high mobility of nodes and multipath propagations. It is highly deployable, self configurable and has dynamically changing topologies. It may connect hundreds to thousands of mobile nodes. Routing protocols of mobile ad-hoc networks differ from the existing internet protocols which are designed for the fixed structure based wireless networks. MANET protocols have to face high challenges due to dynamically changing of topologies, low transmission power and asymmetric links. Due to link instability, node mobility and frequently changing topologies routing becomes one of the core issues in MANETs. A suitable and effective routing mechanism helps to extend the successful deployment of mobile ad-hoc networks. Currently existent routing protocols provide routing solutions up to a certain level and most of them are designed and implemented in small areas. Many researchers are still working on the developments of MANET routing protocols. In our thesis, we are going to concentrate on DSDV , AODV , TORA, LDR and ZRP routing.

1.1 INTRODUCTION TO MANET
Wireless networks are playing a major role in the area of communication. Now we are using wireless networks in military applications, industrial applications and even in personal area networks. Previously, the main difference between wireless and wired networks was only in communication channel. There exist physical medium in wired networks, while on the other side physical medium doesn‟t exist on the wireless networks. Wireless networks became very popular in different applications considering the following factors: ease of installation, reliability, cost, bandwidth, total required power, security and performance of network [3].
