A concept for Sensor Web Enablement employment in a high-volume layered sensing simulation environment

Layered sensing brings multiple heterogeneous sensors together for exploitation and analysis in a variety of ways. Combining a high volume of real-time sensor data with a standard Sensor Web Enablement (SWE) architecture provides a difficult challenge as software and hardware is stressed to operational limits. Simulations of layered sensing environments make excellent testbeds for SWE solutions due to the controllable nature of inputs and outputs. This paper presents a concept for developing a simulation of a layered sensing environment to investigate the ability of a SWE-based architecture to handle a real-time, high-volume stream of data. This work in progress system simulates a physically secure facility and a large number of related security sensors using the OpenSim modeling and simulation environment. Sensor data is then fed into an adaptation of 52North´s SWE architecture, specifically the Sensor Observation Service (SOS) module. The data is then used in a decision support role by a user tasked with monitoring the physical security of the facility.
