In this paper, the authors compared single path and multipath routing protocols over mobile ad hoc wireless networks using ns-2 simulator. Simulation results are presented by varying number of source, pause time and node mobility. Multipath routing protocols for MANETs main objectives are to provide reliable communication and to ensure load balancing as well as to improve Quality of Service (QoS) of MANETs. The main objectives of MANET are providing a solution to the user connected anytime, anywhere to a network. This kind of network is spontaneous, self-organized and self-maintained. The primary challenge of routing in such an environment is to cope with node mobility, which leads to frequently changing network topology.
