Mobile Ad Hoc Network is a complex system which comprises of dynamic, self-configured, distributed in manner wireless mobile nodes allowing people and wireless devices to communicate seamlessly without the need of any pre-existing infrastructure. It is an evolutionary research area which is growing in interest day by day. This book aims to enlighten the arena of MANET; routing protocols, classification, and simulation. This book also demonstrates the simulation environment for most promising AODV and DSDV protocol and evaluate their performance on the basis of various network parameters.
