Abstract

The invention discloses a wireless sensor actuator network data collecting and clustering method based on event driving. The wireless sensor actuator network data collecting and clustering method is characterized by comprising the steps of route establishment, information interaction, cluster establishment, data transmission and adjustment of routes and clusters. The wireless sensor actuator network data collecting and clustering method based on event driving provided by the invention is used for carrying out the division of data collection clusters based on time delay sensing and has the advantages that the efficiency of data collection process is improved based on event driving, and the real-time performance of coordination between the wireless sensor and the actuator in a wireless sensor actuator network is optimized.

Description

technical field [0001] The invention relates to the technical field of wireless network protocols, in particular to an event-driven wireless sensor actuator network data collection and clustering method. Background technique [0002] Wireless sensor networks with actuators are called Wireless Sensor and Actor Networks (WSANs), which is a research hotspot in the field of wireless sensors in recent years. In the wireless sensor actuator network, the sensor nodes are responsible for detecting the surrounding physical environment, uploading the collected data to the actuator nodes, and the actuator nodes are responsible for collecting these data, making decisions based on the information contained in the data and Perform the corresponding action. This heterogeneous network inherits the advantages of distributed data collection and ad hoc network transmission of wireless sensor networks, and cooperates with the characteristics of actuators to perform actions based on collected i...
