This paper presents a framework for representing and distributing access control policies in distributed heterogeneous systems. Access control polices follows the RBAC (Role Based...
Due to node mobility and limitations on bandwidth availability in wireless channels, there exist unique challenges towards achieving efficient and effective information access in ...
It is a challenging task to provide Quality of Service (QoS) control for a shared high-speed downlink packet access (HSDPA) wireless channel. In this paper, we first propose a ne...
The intent of peer data management systems (PDMS) is to share as much data as possible. However, in many applications leveraging sensitive data, users demand adequate mechanisms to...
