In wireless ad hoc networks mobile stations or nodes are free to move around. The transmission range of the nodes is fixed in Mobile Ad hoc NETworks (MANETs) whereas the network topology changes in a different fashion. Due to dynamic nature of network topology some of the network links are destroyed while some new links are established. The routing protocols developed for wired networks cannot be used efficiently for wireless networks. For wireless ad hoc networks there are a few new routing protocols suitable for the dynamically changing ad hoc wireless environment. In this paper the authors compare the performance of two on-demand routing protocols (AODV and DSR) in terms of QoS parameters such as throughput, minimum, maximum & average delay and packet delivery ratio.
