Mobile Ad Hoc Network

Abstract

As a new generation of wireless communication system, mobile ad-hoc network has developed greatly during the past ten years. Endowed by great mobility, dynamic topology, self-organizing and other unique features, it is commonly used in emergency operations, disaster relief efforts and military networks. However, this new wireless network has lots of technical challenges and potential benefits need to be discovered and conquered. Without a doubt, we will soon be able to see ad-hoc network deployment everywhere in the near future. This thesis first introduces the concept of mobile ad-hoc network including its main features, network structure and applications. Then, it focuses on one of the key issues of the ad-hoc network---routing. Finally, on-demand routing protocol (AODV, DSR, TORA) is selected and compared in simulated small-scale networks by using the software OPNET Modeler, aiming to find differences in their performances.
