SYSTEM AND METHODS FOR CONTROLLING MONITOR NODE IN WIRELESS SENSOR NETWORKS

摘要

PURPOSE: A system for controlling the monitoring node of wireless sensor network and a method for the same are provided to expand the entire life expectancy of the wireless sensor network by improving energy efficiency. CONSTITUTION: A base station node(110) is in connection with the terminal(20) of a user through external network. The base station node provides generated event information to the terminal of the user. Detecting nodes(131) detects the event information and transmits setup packets containing the event information. At least one transmission nodes(135) transmit the setup packets to the base state node. The base station node sets the number of the detecting nodes based on measured energy, the number of hops, or the number of damaged nodes on a transmission path composed of the transmission nodes.
