In this paper the Northrhine-Westphalian metacomputing initiative is described. We start by discussing various general aspects of metacomputing and explain the reasons for founding...
Indoor localization is of great importance for a range of pervasive applications, attracting many research efforts in the past decades. Most radio-based solutions require a proce...
We investigate if WiFi access can be used to augment 3G capacity in mobile environments. We first conduct a detailed study of 3G and WiFi access from moving vehicles, in three dif...
In this paper we present a sensor inter-vehicle communication protocol based on geographical routing. Sensors installed in cars continuously gather important information about: ai...
We propose a sensornet programming model based on declarative spatio-temporal constraints on events only, not sensors. Where previous approaches conflate events and sensors becaus...
