Performance of Prefix Delegation-Based Route Optimization Schemes for NEMO

A number of prefix delegation-based schemes have been proposed in the literature to solve the route optimization problem in NEMO, where a group of hosts move together as a mobile network. The route optimization solutions generate different amounts of overheads that depend on the characteristics of the mobile network and mobility parameters. The overheads limit performance, giving rise to the need to carry out a comparative performance evaluation of the schemes to aid in the selection of a scheme; currently there is no tool which can aid in the selection. The objective of this paper is to develop analytical models to allow comparison among the schemes, and selection of an appropriate scheme for a given mobility scenario and mobile network characteristics. Results show that a single scheme does not suit all mobility scenarios and network characteristics. Selection of a scheme should, therefore, consider adaptation to the scenario and characteristics. The schemes could also be extended to dynamically adapt to changing scenario and characteristics.
