Objectives: To provide characteristics of several routing algorithms by discussing the benefits and limitations in relevance to various metrics namely number of packets send, Packets dropped, delivery ratio and throughput. Methods/Statistical analysis: Some well known network simulators are available like Ns2 (Network Simulator 2), Ns3 (Network Simulator 3), OPNET, OMNeT++, Net Sim, REAL, Q. In order to achieve the objectives we shall be using simulator with the name of “network simulator - NS (version 2.35)” for the practical work. It is well known simulator and is an open source. So one can easily modify and add the new code according to their requirements. Findings: Nodes can be created in wired and wireless media using NS-2.35. These nodes can be assigned properties according to their characteristics and need of traffic. Analysis of routing algorithms has been done for 10, 30 and 40 nodes. From analysis it has been demonstrated that no. of packets dropped in AODV, DSDV, DSR and Want Net are equal to zero. No. of packets send is maximum in Want Net as compared to other routing protocols with whom the comparison has been done like AODV, DSDV and DSR. Delivery ratio is 100% in all the routing protocols AODV, DSDV, DSR and Want Net which are taken in this research paper. Throughput that represents the number of packets which are sent effectively per unit time is maximum in WAntNet as compared to other routing protocols AODV, DSDV and DSR .We have done the simulations using NS 2.35 in order to prove the benefits of WAntNet over the routing protocols that are existing in the literature. Improved performance has been attained through the WAntNet. Application/Improvements: MANET is infrastructure less network which is helpful in allocating information using movable devices. The various applications include Military Sector, Commercial Sector, Data Networks, Emergency Services and Sensor Networks.
