ROUTING METHOD USING BROADCASTING MESSAGE OF SINK NODE IN WIRELESS SENSOR NETWORKS

摘要

PURPOSE: A routing method using a broadcast message of a sync node in a wireless sensor network is provided to reduce transmission and reception data amount by changing an updating method. CONSTITUTION: A sync node broadcasts a route message(20) including a route which is facing to a node. Plural sensor nodes update a routing table based on the received route message. The route message includes a route message identifier(210) and the information of a target node. The information of a calling node includes a residual energy level(228) and a hop count(226) which is restricted from the node to the sync node.
