Responsive alert delivery over IP network

Intelligent Guards against Disasters (iGaDs) are devices and applications deployed pervasively in future smart homes and environments. By receiving and processing standard-based machine-readable disaster alert messages from authorized senders and taking appropriate actions in response, they aim to help us better cope with natural disasters. The focus of this paper is on responsive delivery of alert messages over an IP network to a huge number of embedded iGaDs. The Asynchronous Message Delivery Service (AMeDS) is designed for this purpose. After presenting an overview of iGaDs and AMeDs, the paper describes an end-to-end scheduling mechanism used by AMeDS and discusses performance limitations in pushing time-critical alerts to iGaDs over the Internet.
