Remotely Deployed Virtual Sensors Model
Abstract
In this paper, we focus on supporting remote heterogeneous
monitoring, in which applications that run on mobile
client devices connect to the sensors of a multihop sensor network.
For emerging pervasive computing environments, the ability to
remotely retask sensor networks for different applications will be
indispensable. This requires combining the basic physical sensor
data available in the network to provide tailored application-level
data. In our approach, the necessary data types and aggregation
functions are encapsulated in a message and sent to a node that
becomes the virtual sensor coordinator. This node modifies its
behavior based on the received message, obtains the necessary
data from the virtual sensor's participants, and performs the
required aggregation before sending the result back to the client.
This paper reports on our initial work with remotely deployed
virtual sensors and results of our implementation.
