DSDV, AODV & DSR Routing Protocols in MANET Using NS2 –A Performance Comparison

Mobile Ad-Hoc network is a collection of wireless: mobile (hosts) which forms a temporary network without the help of any centralized administration. It is a dynamic network not characterized by any presence of preset communications. In such a type of networking, the nodes which are connected act like a router that discovers as well as maintains the paths to other nodes ahead in the system. In MANET, nodes are able to move and coordinate with their neighboring nodes. Connections in the network can change dynamically due to mobile network. Nodes can be removed or included as required. The proposed work compares routing protocols DSDV, AODV and DSR in Mobile Ad-Hoc network by means of network simulator-NS2. Metrics such as proportion of packet delivery, throughput and end-end delay take part in performance analysis.
