Performance Comparison of AODV, DSDV and DSR Protocols in Mobile Networks using NS-2

Background/Objective: To ensure about which protocol is best for mobile networks by comparing the performances of DSR, DSDV and AODV protocols using NS-2. Method/Statistical Analysis: The functionalities of the three protocols have been compared by the three performance metrics such as Packet Delivery Ratio, Control Overhead and End to End Delay for the changing scenario. Findings: By comparing the packet delivery, it is clear that DSDV protocol is not good but, by comparing the control overhead, DSDV has very high control overhead than DSR and AODV protocols. AODV protocol performs well in some cases but considering the overall performances, DSR performs good than AODV protocol. Improvements/Applications: The protocols design will be improved to adapt themselves for all the changing scenario of the networks and this will be helpful in many applications such as military applications, emergency rescue operations, exploration missions etc.
