  • 摘要:With advantages of IOT (internet of things) and sensor technique, a new communication mechanism between sensors is enhanced upon which distributed emergency response systems are built. This mechanism enables sensors to cooperate with each other in a decentralized way to improve efficiency in case of emergencies. During the process, the alert messages are exchanged among sensors cooperatively to prepare and implement monitoring activities. The system center won’t be overloaded by flooding messages. However, due to the lack of centralized information processing, there will be message loops and identity confusions, which would affect system’s reliability and credibility. For this problem, an approach called Decentralized Message Broadcasting Process is introduced to address the issue. In the approach, a message protocol is developed. The sensors are wrapped as device node services and work as message relay stations when they receive messages from others. Messages are utilized not only as information about event but also as reference to identify and filter. The requirement of reliability and credibility over the distributed emergency response system is achieved. Upon the approach, a platform is built for CEA’ SPON to support the decentralized earthquake emergency response research applications.
