Timeout control for in-network data aggregation in sensor networks considering packet size limit

摘要

According to the present invention, a method for efficiently setting a waiting time before transmitting aggregated data set by each sensor node when using an in-network data aggregation scheme in a sensor network is disclosed. According to the present invention, the data to be collected has a low compression rate, but can be transmitted in a single packet, and the number of data that can be contained in one packet is currently accumulated in the node on the assumption that the data is limited due to a packet size limit. Set different wait time limit according to the number of data. The latency control method proposed in the present invention can increase energy efficiency and lower communication delay time in data collection applications.;Sensor network, in-network data aggregation, waiting time before transmission (timeout)
