This paper describes the wireless sensor networking testbed built at the IBM Zurich Research Laboratory. The testbed has been used to address a wealth of exciting research challenges. Performance evaluations have been carried out with short-range wireless communication technologies, which are highly relevant for sensor networking such as IEEE(More)
We present a novel power-efficient wireless sensor network for continuously monitoring and analyzing seismic vibrations with sensor nodes and forwarding the retrieved information with low-cost relay nodes to backend applications. The applied vibration sensing algorithms are derived from the DIN 4150–3 standard. All nodes in the network are(More)
Increasing heat dissipation density is becoming a limiting factor in air-cooled data centers. The main control objective in data center thermal management is to keep the temperature of all the data processing equipment below a certain threshold and at the same time maximize the energy efficiency of the system. Existing work in this field does not take into(More)
To enable new context-aware applications and services in future communication systems, wireless sensor networks (WSNs) are required to capture the context surrounding the service user and service related objects. This paper introduces a novel configurable architecture for a WSN system that is able to deliver context information from the sensors to the user(More)
