Analysis Performance of Different Routing Protocols for MANETs using NS2 Simulator

Abstract: To put it simply, a Mobile Ad-Hoc Network (MANET) is indeed a network of wireless mobile hosts that have formed temporarily without the use of any dedicated infrastructure or centralized administration. The network's nodes are selforganizing & self-configuring because of their mobility. The hosts also serve as routers. Their job is to route information to and from other network nodes. Routing protocols are essential in MANETs because they determine the best ways to get from one node to another. Any ad hoc network's routing protocol should be designed with the ever-evolving topology in mind. For this reason, it is important to set up a path between any two nodes that uses as little bandwidth as possible and as few hops as possible in the routing process. Due to the transient and ever-changing nature of mobile ad hoc networks, designing suitable routing protocols is difficult. For MANETs, routing protocols can be either proactive or reactive. Features and difficulties of MANETs are discussed in this work. Furthermore, both proactive and reactive routing systems, as described earlier, are discussed in detail. Additionally, DSDV, DSR, and AODV are compared with one another in terms of attributes and performance. Finally, certain articles that have dealt with routing in MANET are critically examined.
