In the vision of ubiquitous computing, there are billions of context sources that continuously publish their contextual information, and even more user agents that search for and ...
When analyzing dissemination protocols in mobile adhoc networks the underlying mobility model is an important factor because it strongly influences the performance of these protoc...
We investigate the theoretical limits of positioning algorithms. In particular, we study scenarios where the nodes do not receive anchors directly (multi-hop) and where no physica...
To allow for an efficient usage of a device in pervasive computing environments, reliable and yet convenient user access is an important requirement. The problem becomes more comp...
Energy-aware algorithms have proven to be a crucial part of sensor network applications, especially if they are required to operate for extended periods of time. Among these, effic...
