DIVISOR: Dynamic virtual sensor formation for overlapping region in IoT-based sensor-cloud

In this work, we propose a scheme for the formation of Dynamic Virtual Sensor for Overlapping Region (DIVISOR) in a IoT-based sensor-cloud platform. Practically, the interest of deployment area of similar sensor nodes by respective sensor owners may be the same, and consequently, the areas of coverage of the deployed sensor nodes of the different owners overlap with one another. Thus, in such a scenario, each of the sensor owners must get equal opportunity to earn profit from the deployment of their sensor nodes. Therefore, in order to provide an equal privilege to all sensor owners, we propose the scheme, DIVISOR, in order to form virtual sensors. This is one of the first attempts for the dynamic formation of virtual sensors, where the overlapping area of deployed sensor nodes by different sensor owners is considered. The experimental results demonstrate that the proposed scheme is energy-efficient and the average number of participating nodes increases with the increase in the total number of nodes in the network. Moreover, each sensor owner gets almost equal opportunity to rent their nodes.
