| Summary: | There are two approaches to handle the convergence of mobile sub-networks in the Personal Distributed Environment (PDE). In order to make decision which approach to be used in the PDE, a simulation model was developed to compare the approaches. Based on the simulation model and also analytical studies, performance evaluations were carried out on both approaches. This study will start with the introduction of the PDE concept and followed by the overview of the protocol used to support network mobility in PDE. The explanation of the simulation model and its environment will then follows. This is then followed by the explanation on the implementation of both approaches in the simulation model. The de-convergence of the sub-networks using both approaches will also be discussed. This will then be followed by the discussion on the metrics used to carry out the performance evaluation together with its derivation. The results from the evaluations will then be presented. At the end of this study, the most suitable convergence approach of mobile sub-networks in the PDE will be determined. © 2009 Asian Network for Scientific Information.
