Service process modelling and performance analysis for composite context provisioning in IoT

الملخص EN

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
