Abstract:
Random motion is often used in evaluating performance of Mobile Ad hoc Networks (MANETs). Mobility pattern of nodes significantly affects performance of MANETs. In the simulation of large mobile networks, automated movement generators are used, such as the setdest utility in ns2. In this paper, we investigate the modifications to the standard setdest generator that specifies the motions along straight-line paths. We propose and implement a new method for movement generation for the ns2 simulator that specifies the node movements along curved paths generated using simple fractals. The new generator was successfully tested with the ns2 simulator. The results show that, in the random way point motion, only the node speed significantly affects MANET performance, and not the shape of the individual path segments taken by a node.
