Traffic demands in mobile networks are expected to grow substantially in the next years, both in terms of total traffic volume and of bit-rate required by individual users. It is generally agreed that the only possible solution to overcome the current limitations is to deploy very dense and heterogeneous wireless networks, which we call DenseNets. However,(More)
Telecommunications networks are undergoing major changes so as to meet the requirements of the next generation of users and services, which create a need for a general revised architectural approach rather than a series of local and incremental technology updates. This is especially manifest in mobile broadband wireless access, where a major traffic(More)
IP mobility management has a key role in wireless networking and mobile Internet. The existing IP mobility protocols are deployed generally in a centralized manner. All the data traffic passes through a centralized entity and all the bindings are managed at this entity as well. Recently, various efforts from both industry and academia are being performed on(More)
In this paper, we investigate the resource management and scheduling issues for the future UWB-based high-rate WPAN systems. Based on a distributed management architecture, we propose a novel multiple access scheme in the context of multiuser channel and time allocation for the UWB applications. Using a self-learning and managing approach, the distributed(More)
Recently, various efforts are being conducted on specifying Distributed Mobility Management (DMM). DMM aims at eliminating the limitations of current mobility protocols in order to cope with the rapid growth in mobile data traffic. However, the DMM schemes face generally the location management issue. In this paper, we propose a location management approach(More)
