Abstract: The recent increase in the research interests towards a smart life
style has introduced a huge number of devices into our life. Some devices are
being used by us such as the smart phones while others are most of the time
invisible to us such as proximity sensors and light sensors etc. These devices
are being interconnected via Internet and are being utilized to read an
environment, detect patterns and predict or forecast some events. Sharing the
data and information collected by these desperate devices to clients over the
Internet is called as Provision. Due to disparity in the hardware and software platforms
for sensing devices, the provisioning services are also limited to providing
contextual data based on single provider and there is no generic process model
which can be utilized for composite context provisioning from multiple
providers. This paper presents a service-oriented process model for composite context
provisioning. A step by step explanation has been provided for each process
involved and performance analysis has been carried out using a prototype
implementation of the model.
Keywords: Composite context, provisioning service, sensing, data
collection, service-orientation.
