Performance Analysis and Evaluation of Routing Protocols for Mobile Adhoc Networks

MANET is a self-ruling assortment of dispersed mobile users. Every host that exists in MANET bear packets for other available hosts and work itself as a source and sink and thus works as a router as well. In MANET, every node action as a router and an end node which may either be a source or destination. Thus, it may happen that the breakdown of some node's operation can enormously crimp the shooting of the network and also influence the elemental opportunity of the network. The present paper compares and simulates significant attributes of one proactive protocol (DSDV) and three reactive protocols (AODV, DSR, TORA) on the criteria of various performance metrics viz. throughput, PDR, nodal delay, scalability, overhead, energy consumption etc. Our simulations demonstrate that proactive protocol (AODV) is best suitable for energy consumption and scalability. AODV has low PDR and steep routing overhead although good throughput and less nodal delay.
