The invention relates to a
data transmission delay and hop count-constrained Sink node movement path distributed
selection method. The method includes the following steps of movement path calculation of a Sink node; and data communication of sensor nodes. The movement path calculation of the Sink node further comprises the following steps that: 1.1) after a network is started,
sensor node information is collected; 1.2) a virtual repulsive force, a virtual attractive force and the
resultant force of the virtual repulsive force and the virtual attractive force are calculated; 1.3) the stay time of the Sink node at a current grid center is calculated according to the magnitude of the
resultant force; 1.4) the center of a next grid center is calculated according to the direction of the
resultant force and the
residual energy of the sensor nodes; and 1.5) if the sum of the stay time of the Sink node on all the selected grid centers does not exceed a
data transmission delay maximum value, the method returns to 1.1), otherwise, data are collected circularly along an obtained movement path. The data communication of the sensor nodes includes a node
residual energy-based data routing method and
data transmission. With the method of the invention adopted,
time complexity can be effectively reduced, and data collection amount and node coverage rate can be improved, and the loss amount of the
sensing data of the sensor nodes can be decreased.
