Abstract
Today the world is moving towards wireless system. Wireless networks are gaining popularity to its peak today, as the users want wireless connectivity irrespective of their geographic position. In these networks, devices are used as nodes. Recently many researchers have been done their work on MANET. In this work nodes have been used as devices and based on comparison between three mostly used routing protocols Ad hoc on demand distance Vector routing protocol (AODV), Dynamic source routing protocol (DSR) and Destination sequence based distance vector routing protocol (DSDV) in MANET scenario with 20 nodes, 60 nodes and 100 nodes with different mobility which are 5m/sec, 10m/sec and 15m/sec and performance has been calculated on the basis of Residual energy, packet delivery ratio, throughput and end to end delay with different environment. The tool chosen for this work is NETWORK SIMULATOR (NS2).
