An efficient notification service algorithm for earthquake early warning system

Earthquake Early Warning Alarm Notification is a service that addresses devices and users with messages to be processed at a specific time. In this paper, we propose an efficient notification algorithm for earthquake early warning system in Taiwan. Due to the lack of multicast support in the general IP network, we try to deliver notification messages to multiple receivers in time base on location information, network throughput with peering ISPs and priority with IoT devices. With the proposed algorithm, we can not only reduce the burst message traffic for network but also send the messages in time. By the SIP protocol, we can integrate various devices into the same communication platform.
