1 b Abstract— In this paper promising technologies and a network architecture are presented for future Optical Packet Switched networks. The overall network concept is presented and the major choices are highlighted and compared with alternative solutions. Both long and shorter term approaches are considered as well as both the WAN and MAN parts of the(More)
Energy consumption has increased considerably in the last years. How to reduce and make energy consumption more efficient in home environments has become of great interest for researchers. This could be achieved by introducing a Home Energy Management System (HEMS) into user residences. This system might allow the user to control the devices in the home(More)
— Future mobile communication systems such as IEEE 802.16 are expected to deliver a variety of multimedia services with diverse QoS requirements. To guarantee the QoS provision, appropriate scheduler architecture and scheduling algorithms have to be carefully designed. In this paper, we propose an adaptive bandwidth distribution algorithm for the aggregate(More)
In this paper, two approaches for Dynamic Bandwidth Allocation in GPON networks are proposed, and validated through simulations in the OPNET modeler. One approach address a Status Reporting scheme, where the bandwidth allocation originates from the client request. The second use a centralized Non Status Reporting scheme. Furthermore, parameters to cope with(More)
The paper aims to introduce an approach that integrates a technique of knowledge engineering (Ontologies) and a technique of quality engineering (Failure Mode and Effects Analysis). An approach will be set up that shows the potentials of combining IT-based systems of knowledge and quality engineering. Particularly with regard to the quality engineering(More)
