Abstract: This paper introduces a cluster header algorithm focused on concepts and characteristics. For the purpose of data aggregation, centered on real-time data, it designs the routing algorithm based on the event-driven networks. It differentiates every node and chooses the best header and founds the configuration of transmitting tree to guarantee the real-time characteristics. It effectively reduces the transmission of information and the delay of propagation.

Key words: data aggregation, header, event-driven
