  • Method and apparatus for automatic repeat reQuest (ARQ) in broadband wireless access system
    Patent number: 9432151
    Abstract: An apparatus and a method for Automatic Repeat reQuest (ARQ) in a broadband wireless access system are provided. The method includes driving a timer which operates by a preset period to synchronize ARQ between the transmitter and a receiver; after transmitting data to the receiver without error, when a driving time of the timer expires, checking whether there is data to transmit to the receiver; when there is no data to transmit to the receiver, initializing the timer; and transmitting an ARQ reset message to the receiver. Hence, the air resource consumption and the power consumption in ARQ reset can be lowered by reducing unnecessary ARQ reset.

  • Terminal node device and wireless sensor network system using the terminal node device
    Patent number: 9420624
    Abstract: Provided is a terminal node device including: a communication module communicating with an external sink node device and another terminal node device; sensor modules; and a control unit allowing the terminal node device to be operated while allowing the terminal node device to transition into one of the initial, synchronous, and leave states. In the initial state, the control unit scans a received message; if a beacon message is received from a sink node device, the control unit transitions into the synchronous state; and if not for a predetermined time, the control unit transitions into the leave state. Accordingly, if a beacon message is received from the sink node device, the terminal node device transitions into the synchronous state to constitute a server-based wireless sensor network; and if not, the terminal node device transitions into the leave state to constitute an independent sensor network.
