Abstract: Disclosed is an asynchronous MAC based sensor node using a Wake-Up RF. The sensor node includes a main transceiver to transmit/receive data, a Wake-Up transceiver to transit a state of the sensor node; and a micro-control unit, which transmits a Wake-Up frame to at least one receiving node through the Wake-Up transceiver such that the receiving node is activated from an inactive state into an active state and transmits data to the activated receiving node through the main transceiver. The asynchronous MAC based sensor node reduces unnecessary power consumption, hop-by-hop delay, and overhead required for timing synchronization, thereby implementing an effective sensor

Abstract: PURPOSE: A method and apparatus for setting a packet are provided to serve as a server by using a conventional user terminal serving as a client of IP socket communications without establishment of port forwarding of a PPP(Point to Point Protocol) server or an IP sharing device. CONSTITUTION: A user terminal obtains a domain name of a MTC(Machine-Type Communications) device and a public IP address of an IPFS(IP Packet Forwarding Server)(S802,S804). The user terminal requests call identifier allocation of the IPFS for connecting to an MTC device(S806). The IPFS assigns one of available TCP/UDP(User Datagram Protocol) communication ports to a call identifier(S808). The IPFS transmits a wake-up signal(S810). The MTC device attempts TCP/UDP socket establishment(S812). The IPFS registers the call identifier and an NAT(Network Address Translation) IP, a port number, and a life cycle value of the MTC device in a packet forwarding information management table(S814). The call identifier is transmitted to the user terminal(S816).

Abstract: PURPOSE: A sensor node equipped having a wake-up module, a wakeup sequence control device, and a method thereof, are provided to control the wakeup sequence of MCU by using a hardware module. CONSTITUTION: If a beacon frame is transmitted or received, a MCU(200) confirms the information of the beacon frame. A MCU establishes registers. MCU converts a present mode into a sleep mode. If the interrupt is inputted, the MCU is converted from the sleep mode into an active mode. A wake-up module(300) multiplies the counter value in case of establishing the registers. A wake-up module outputs the interrupt according to the comparison result of the counter value and the BI(Beacon Interval) value identified from the beacon frame.

Abstract: A method for configuring a network of nodes with a tree structure is provided to reduce network reconfiguration overhead caused by autonomous withdrawal of the nodes or consumption of a battery in a sensor network with a tree structure. A method for configuring a network of nodes with a tree structure comprises the following several steps. It is checked whether or not the first node has child nodes, and withdrawal is requested to a parent node if the first node has not child nodes(101,103). One among the child nodes is selected on the basis of remaining power of the child nodes if the first node has child nodes(101,105,107). The first node exchanges positions with the selected child node and withdrawal is requested to the parent node if the selected child node has no child node(109,111-115). The steps of 105,107,109, and 111-115 are repeated if the selected child node has child nodes(109,117,119).
