Handling the Convergence of Mobile Sub-networks in a Personal Distributed Environment

A personal distributed environment (PDE) is a personal communications concept designed for future mobile communications. In a single PDE, there exist several subnetworks hosting devices located across the infrastructure, which will inter-work with one another through the coordination of a device management entity (DME). Some of these sub-networks are fixed and some are mobile. One of the issues concerning the mobile sub-networks in a PDE is the convergence and de-convergence of mobile sub-networks. In this paper a comparison is made between two approaches proposed to handle the convergence and de-convergence of mobile sub-networks by use of a detailed simulation model.
