A Study of Routing Protocols Based on Different Models in MANET
Satyam Kumar Sainy, Ravi Rai Chaudhary · 2015
The main characteristics of Mobile Adhoc NETwork (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 study we have chosen three routing protocols namely AODV (Adhoc On demand Distance Vector routing), DSR (Dynamic Source Routing) and LAR1 routing protocol on the basis of packet delivery ratio, routing overhead, average end-to-end delay and Number of Hope Count using Glomosim simulator. Three different models are created by changing few parameters of traffic generator file and scenario file like pause time, speed of mobile nodes and network size. The selection of an efficient routing protocol thus depends on different parameters of the MANET.
