Investigation of NS-2 movement file generation for a curved path

Abstract

MANET is a decentralized wireless network, having no fixed infrastructure or designated routers. In MANT, mobile nodes move dynamically and follow tracks that determine the mobility pattern in the network. Mobility of mobile nodes significantly affects MANET performance. The simulation of large mobile networks depends on movement generation, such as the Setdest utility in NS-2. In this research, we investigate the standard Setdest generator that specifies the motions along straight-line paths. We propose and implement a new method for movement generation in the NS-2 that specifies the motions along curved paths. The new generator was successfully tested with the NS-2 simulator. From the results we conclude that only the node speed significantly affects MANET performance, and not the shape of the path taken by a node.
