— In this paper, we study cross-layer design for rate control in multihop wireless networks. In our previous work, we have developed an optimal cross-layered rate control scheme ...
In virtual environments, head pose and/or eye-gaze estimation can be employed to improve the visual experience of the user by enabling adaptive level of detail during rendering. In...
Timelines are recurrently used to design visualization techniques of temporal data. In this paper, we present our perspective wall timeline to visualize temporal values. We illust...
We consider the fundamental problem of authenticated group key exchange among n parties within a larger and insecure public network. A number of solutions to this problem have bee...
It is a widely held belief among designers of social tagging systems that tag clouds represent a useful tool for navigation. This is evident in, for example, the increasing number ...
