the proceedings contain 4 papers. the topics discussed include: wireless sensor networks in the wild: three practical issues after a middleware deployment;language and middleware support for dynamism in wireless sensor and actuator network applications;querying context maps using relative timing predicates in pervasive environments;and distributed configuration and processing for sensor networks.
In contrast to traditional sensor networks, the "Internet of things" focuses on interactions between humans and physical objects rather than on sensing and reporting low level information. While several midd...
