A METHOD FOR COMMUNICATION USING VIRTUAL SINK NODE IN A WIRELESS SENSOR NETWORK AND AN APPARATUS THEREOF

摘要

A communication method using a virtual sync node of a wireless sensor network and an apparatus thereof are provided to construct a network environment suitable for the one to many communication through the virtual sync node. In a sensor network, specific data of an installed region is sensed through sensor nodes(1,2,3), and data is concentrated on sync nodes(5,6) through a virtual sync node(4). When the data is transmitted to an external network such as the Internet through the sync nodes, a user can use the data. The destination node of the sensor nodes is the virtual sink node.
