Abstract—Mobile ad hoc network (MANET) is a group of mobile nodes communicating through wireless channels without the necessity of any pre-established network infrastructure or centralized administration. Because of the limited transmission range of wireless nodes, multiple hops may be needed for effective communication across the network. Consequently, many routing algorithms have come into existence to satisfy the needs of communication in such networks. Researchers have conducted many experiments/simulations comparing the performance of these routing protocols under various conditions and constraints. One question that arises is how scalability and mobility of nodes together, affects the performance of routing protocols. This paper addresses the question by simulating two routing protocols AODV and DSR using QualNet and was compared in terms of throughput and average end-to-end delay. Simulation results illustrate that the throughput of DSR increases as compared to AODV with the increase in number of nodes and pause time, whereas average delay for AODV decreases with mobility and scalability.
