The SENSE-ME platform: Infrastructure-less smartphone connectivity and decentralized sensing for emergency management

Moreover, we introduce a realistic usage scenario (building evacuation), characterized by the presence of Android devices deployed over a two-dimensional space. Through SENSE-ME, each smartphone is able to quantify its level of danger by analysing its sensor data, to share such metrics with the surrounding devices via Wi-Fi Direct links, and finally to detect an emergency event, and compute a safe path, by applying a consensus-based algorithm to the received observations. In this scenario, we present a modular evaluation of the SENSE-ME networking/sensing/information processing components, clearly highlighting the strengths of a multi-layer approach for emergency monitoring and management.
