Cooperative sensor-clouds for public safety services in infrastructure-less areas
Sarra Berrahal, Noureddine A. Boudriga, Antoine Bagula · 2016
The integration of wearable and integrated sensing technologies with cloud computing has the potential to promote the development of large-scale monitoring applications and to provide public safety as a service to end-users. In this paper, we proposed a system that relies on the integration of heterogeneous sensor networks and cloud computing to build distributed public safety databases and to provide cooperative composite services provisioning in infrastructure-less areas. The contributions are three fold. The first contribution consists in designing a Sensor-Clouds based architecture that integrates different WSNs and cloud computing and aims to report on the evolution of a particular set of public safety threats. The second contribution focuses on describing a system model for composite Sensor-Cloud services provisioning that allows to identify and classify the sensor-cloud services that can be made available to end-users regardless of the geographical distribution of sensor networks. The third contribution describes a two-layer composite service delivery in order to efficiently cover several services requested by end-users. While, the first level defines a static composite service delivery the second level defines dynamic composite services that are delivered and versioned based on a set of heuristics to address users' requirements and expectation. The proposed approach is evaluated through a simulation.
