Performance Evaluation Of Ad Hoc Wireless Networks

ABSTRACT : Mobile wireless ad hoc networks represent an important tool and technology to provide data communication in places where wired networks are not available. An ad hoc network is composed of mobile nodes without any infrastructure. Mobile nodes self organize themselves to form a network over radio links. Multicasting, which is the transmission of packets or data between a single sender and multiple receivers on a network, is used as a mode of transmitting information between these mobile nodes. In an ad hoc network, the benefits of using multicasting is that it is more bandwidth efficient than unicasting. In this thesis, a survey on some existing experimental studies and the performance metrics measured have been mentioned. Secondly, a prototype application-layer test bed program is implemented to investigate routing and how data is transmitted in wireless ad hoc networks. Thirdly, various experiments were performed in the indoor and outdoor environment varying distances and data sizes of packets. The results of this study show the actual performance of mobile wireless networks putting into consideration all natural effects that generally affect the wireless networks.
