Special issue on last advances on QoS and security in wireless networks

In recent years, wireless and mobile communication systems have become increasingly popular as the advance of hardware technologies makes the implementation of novel communication technologies feasible. With growing demand of software downloading and mobile multimedia services, the quality of service (QoS) provisioning and the management of network security have been critical in determining the success of future generation wireless communications. This special issue includes cutting-edge research achievements on the provisioning of QoS and security in wireless and mobile networks. The included papers present new research related to theory or practice of all aspects of security issues in ad hoc and sensor networks and QoS provisioning.
