Performance Comparison of Routing Protocols of MANET in Real World Scenario using NS3

Mobile ad hoc network (MANET) is an autonomous system of portable nodes connected by wireless links without using any need for centralized administration. Due to limited transmission range, each node acts as an end system and acts as a router to transmit the packets to destination hop by hop. MANET has certain characteristics like dynamic topology, limited bandwidth, CPU capacity, storage capacity, link failure and energy constraints, which imposes new demands on routing protocol. Each protocol operates differently in different network scenarios. MANET is not popularly used in every day applications, as all the simulations are done on non-real world scenarios. So this paper presents comparisons of AODV, DSDV and OLSR protocols in a real world scenario. Further, simulations are carried out using ns-3 network simulator.
