Abstract--With the price of wireless sensor technologies di-
minishing rapidly we can expect large numbers of autonomous
sensor networks being deployed in the near future. These sensor
networks will typically not remain isolated but the need of
interconnecting them on the network level to enable integrated
data processing will arise, thus realizing the vision of a global
"Sensor Internet." This requires a flexible middleware layer
which abstracts from the underlying, heterogeneous sensor net-
work technologies and supports fast and simple deployment
and addition of new platforms, facilitates efficient distributed
query processing and combination of sensor data, provides
support for sensor mobility, and enables the dynamic adaption
of the system configuration during runtime with minimal (zero-
programming) effort. This paper describes the Global Sensor
Networks (GSN) middleware which addresses these goals. We
