Performance Analysis of Routing Protocols Using Various Parameters in MANET Scenario

ABSTRACT A MANET is a type of adhoc network that can change locations and configure itself on the fly. Because MANETS are mobile, they use wireless connections to connect to various networks. MANET is useful when infrastructure not available, impractical, or expensive. Based on the routing information update mechanism routing protocols can be classified into three major categories:-Proactive, Reactive, Hybrid protocols. Such networks can be deployed anywhere and at any time or the fly. Because of the dynamic nature of MANETs, they are typically not very secure, so it is important to be cautious what data is sent over a MANET. Routing in adhoc-networks has been a challenging task ever since the wireless networks came into existence. The major reason for this is the constant change in network topology because of high degree of node mobility. A number of protocols have been developed for accomplish this task. The objective of the proposed work is to study the Table driven (Proactive) ProtocolsDSDV and Reactive Protocol-AODV protocol performance on the basis of Cumulative sum of no. of all generated packets, Throughput of dropping packets, Packet Size Vs. Average throughput of sending packets, Packet Size Vs. Average throughput of receiving packets, Throughput of receiving bits Vs. Maximal Simulation processing time. Output results are compared using network simulator-2(NS2) between DSDV and AODV.
