Abstract — Since sensor/actuator networks are to be used in error-prone environments, it is required that media access protocols for such networks are tolerant to failures. Field...
This paper presents a novel method for optimizing sliding window based continuous queries. We deal with two categories of aggregation operations: stepwise aggregation (e.g. COUNT) ...
Selecting a small set of nodes called pivots, from all the nodes in a network and maintaining the routing infrastructure to and among each other can reduce routing overhead and ex...
Nowadays more and more devices of daily life are connected to each other and are integrated into massively distributed networks of embedded devices. These devices range from consu...

Due to the long propagation delay and high error rate of acoustic channels, it is very challenging to provide reliable data transfer for time-critical applications in an energy-ef...
