Abstract

The invention provides a multi-mobile-node data collection method. The method is characterized in that k sensor nodes are randomly selected from a wireless sensor network as cluster head nodes; the distance between the other sensor nodes in the wireless sensor network and the selected k cluster head nodes is calculated respectively, and the cluster head node, the distance of which is the smallest, is selected to join in a cluster; in k clusters, each sensor node calculates weighted sum according to residual energy of itself and the distance between the sensor node and the other sensor nodes, and the sensor node, the weighted sum of which is the smallest, is selected as a new cluster head node; if a cluster head changes, clustering is carried out again; after clustering again, in-cluster sensor nodes send the collected data to the cluster head nodes; a plurality of mobile nodes collect data of the multiple cluster head nodes in each circular path; and after data collection, each mobile node transmits the data to a sink node through a collaboration method. The method solves the problem of uneven energy consumption in the network, improves load balance and energy balance in the whole network, and meanwhile, prolongs network lifetime.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor networks, and in particular relates to a multi-mobile node data collection method based on optimizing k-means. Background technique [0002] The wireless sensor network is composed of a large number of sensor nodes with the ability to sense information, wireless communication and data processing. These nodes are randomly scattered in the monitoring area, collect and process information in a cooperative manner, and provide the information to remote users. . Due to the characteristics of low cost, strong adaptability and powerful functions of wireless sensor network, it has broad application prospects in military, medical, smart home, environmental protection and other fields. [0003] Wireless sensor network is a data-centric network, and data collection technology is also the basic technology of wireless sensor network. The biggest difference between wireless sensor networks and other ne...
