PERFORMANCE EVALUATION OF ROUTING PROTOCOLS IN MANET

Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile hosts forming a temporary network without the aid of any stand-alone infrastructure or centralized administration. The primary goal of any ad-hoc network routing protocol is to meet the challenges of the dynamically changing topology. The design of these routing protocols is challenging due to the mobility and the dynamic nature of the mobile adhoc networks. In this study, the MANET characteristics and challenges are highlighted. A comparative analysis has been carried out among three protocols DSR, DSDV and AOVD in terms of network parameters which based on the specific simulation setting such as size of network nodes (100, 150, and 200). The findings indicate that AOVD protocol works more efficient than the others in varying node density in term of packet loss, Normalized routing load (NLR), and Packet delivery ratio ( PDR). According to the examined parameters, AODV shows more efficiency in comparison with DSR and DSDV in term of large scale of network. However, DSR shows a worst efficiency in comparison due to the huge number of loss-packet in contrary with the packet delivery which is very low amount.
