Performance Comparison of Routing Protocols Based on Different Models in Mobile Adhoc Network
Aditi Agrawal, Rajeev Paulus, Alok Singh · 2012
(MANET) are no infrastructure, no centralized administration and self-configuring networks. The primary motivation of MANET deployment is to increase portability, flexibility and mobility but, mobility causes an unpredictable change in topology and makes routing more difficult. Efficient dynamic routing is a research challenge in such networks. In this paper we have evaluated the performance of three protocols namely AODV (Adhoc On demand Distance Vector routing), DSR (Dynamic Source Routing) reactive routing protocol and DSDV(Destination Sequenced Distance Vector) routing which is a proactive routing protocol on the basis of packet delivery ratio and normalized routing overhead using NS-2 simulator. Four different models are created by changing few parameters of traffic generator file and scenario file like pause time, speed of mobile nodes, network size and number of maximum connections and the results demonstrate that the difference in the mechanism of routing protocols lead to specific performance variation. The selection of an efficient routing protocol thus depends on different parameters of the MANET.
