Resources and mobility management in wireless networks

The advent of pervasive wireless communication technologies and the deployment of heterogeneous communication systems and architectures, from cellular communication systems to sensors and ad hoc networks, have fostered the research community to deal with the limitations and new assumptions of the wireless and mobile communication systems. The main limitations typically involve the resources like battery energy, computation and bandwidth. The new assumptions include the unprecedented dynamics caused by mobility, heterogeneity, variable channel conditions, the traffic characterization of new emerging applications and the open, distributed management architecture of wireless communication systems like the ad hoc and wireless sensor networks. This special issue brings together eight contributions on proposals for the resources management and mobility management in wireless networks, from different viewpoints, including QoS support, dynamic channel allocation, fault-tolerance, power saving and power efficiency, clustering and security issues. The papers have been selected from a total of more than 40 submitted papers, due to their originality and contribution to the field of wireless communications and mobile computing, with a particular emphasis on resources and mobility management in wireless networks - the theme of this special issue.
