We study the problem of providing a sensor with an accurate estimate of the time, from a novel perspective which is complementary to the well-studied clock synchronization problem....
In wireless sensor networks (WSNs), sensor nodes are typically subjected to energy constraints and often prone to topology changes. While duty cycling has been widely used for ener...
Authenticating mobile computing users can require a significant amount of processing and communications resources— particularly when protocols based on public key encryption are...
Web services are becoming more and more pervasive and are used by a number of information system clients. However, mobile clients still have limited computing and network resource...
We extend previous work on texture mapping video streams into virtual environments by introducing awareness driven video QoS. This uses movements within a shared virtual world to ...
