Among the schemes, proposed in the literature to solve the route optimization problem in NEtwork MObility (NEMO), the prefix delegation-based schemes perform better than other schemes. Depending on the way the prefix are delegated, the prefix delegation-based schemes result in difference in performance under different speed at various distance from the home network (network to which mobile network usually belongs). Therefore, there is a need to evaluate the performance of individual prefix delegation-based scheme to find an appropriate scheme based on speed and distance from home network. In this paper, the authors identify the differences of the prefix delegation-based schemes using simulation. Results reveal that performance of the schemes depends on speed of the network and distance from home network.
