CLUSTER HEAD NODE SELECTION METHOD BASED ON A DISTANCE BETWEEN NODE AND BASE STATION

摘要

The present invention includes a step in which a base station calculates the distance with all nodes distributed in a sensor field; a step in which the base station transmits the distance with a mode node distributed in the sensor field to each node; and a step in which one of the nodes selects itself as a cluster head node according to probability in which each node is selected as the cluster head node by calculating the probability to be selected as the cluster head node through the distance between the base station and all nodes at each round. [Reference numerals] (AA) Start; (BB) End; (S10) Transmit a test packet from each node to a base station; (S20) Base station calculates a distance with each node by using the signal intensity of the test packet; (S30) Base station transmits the distance with each node to a node
