Ubiquitous Sensor Network System based on Internet Protocol

摘要

PURPOSE: A ubiquitous sensor network system based on internet protocol is provided to construct sensor network through a connection among sensor node groups by transmitting data through multi-hop routing. CONSTITUTION: A slave node(124b) of a first sensor node group is connected to a master node(132) of a second sensor node group through a PPP(Point-to-Point Protocol) interface. If the slave node transmits and receives data with other node in the same sensor node group, the slave node and the master node transmit and receive data through the mobile network based on B-CDMA. In the data communication between the slave node and the master node, the slave node and the master node transmit and receive data through the PPP protocol.
