—Earlier sensor network MAC protocols focus on energy conservation in low-duty cycle applications, while some recent applications involve real-time high-data-rate signals. This m...
Sketches--data structures for probabilistic, duplicate insensitive counting--are central building blocks of a number of recently proposed network protocols, for example in the con...
Flooding is a growing problem, which affects more than 10% of the UK population. The cost of damage caused by flooding correlates closely with the warning time given before a floo...

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...
Peer-to-peer networks and grids offer promising paradigms for developing efficient distributed systems and applications. Event-based middleware is becoming a core architectural el...
