A mobile ad hoc network (MANET) is a collection of mobile nodes dynamically forming temporary network without the use of
any existing network infrastructure or centralized administration. Due to the mobility of the nodes, as well as the continual arrival and departure of nodes, the topology of the network changes constantly. To manage the transmission, routing
protocols are needed. Therefore analyzing performance of the protocols becomes crucial to finding efficient routing protocols. In this work, we show a systematic procedure of using Taguchi parameter design in analyzing Destination Sequence Distance Vector (DSDV) routing protocol performance. Using orthogonal arrays and signal-to-noise (S/N) ratios we determine the most factor influence and the best combination of factor levels. This paper evaluates the impact of terrain size, node speed, network size and pause time on the data
delivery. The study indicated that a maximum ratio of data delivery could be obtained with terrain size of 150m x 150m, node speed of 1 m/s, network size of 200 nodes and pause time of 10 seconds.
