Provided is a communication method and apparatus using a multi-radio. The communication method includes establishing a link via at least one node included in a group that uses a low data-rate radio (LDR); transmitting a data frame to the at least one node included in the group; and receiving, using a multi-radio based on an availability of the LDR, an acknowledgement (ACK) with respect to the transmitted data frame.

Communication method using multi-radio and communication apparatus

A method to regulate a signal-to-noise ratio (SNR) in a rate adaptation includes: transmitting a frame; determining a status of the transmitted frame; computing a probability of a channel of the transmitted frame being in an idle mode; computing an SNR offset based on the status of the transmitted frame and the probability; and regulating an SNR for transmission, based on the SNR offset.

Method and user equipment for effective signal-to-noise ratio (SNR) computation in rate adaptation

An apparatus for transmitting messages between vehicles includes a sensor configured to sense at least one of location information of a vehicle, location information of vehicles neighboring the vehicle, or vehicle information of the neighboring vehicles, an input device configured to receive a first message from a user aboard the vehicle, a processor configured to generate a map based on the at least one of the location information of the vehicle, the location information of the neighboring vehicles, and the vehicle information of the neighboring vehicles, or configured to transform the first message into a transmission message, an output device configured to output the map and the first message, and a communicator configured to transmit the transmission message to a target vehicle, and receive a second message from the neighboring vehicles comprising the target vehicle.

Apparatus and method of transmitting messages between vehicles

A method and apparatus to share energy in a wireless device are provided. A power sharing method between a wireless device and at least one neighboring wireless device, includes scanning, by the wireless device, the at least one neighboring wireless device. The power sharing method further includes determining to share power with the at least one neighboring wireless device. The power sharing method further includes sharing power with the at least one neighboring wireless device.

Provided is an operation method of a coordinator, the method including receiving a data packet from a node, configuring bitmap information indicating whether the data packet is received, and broadcasting a beacon packet including the bitmap information indicating whether the data packet is received.

Operation method of coordinator and node supporting block ACK scheme and link adaptation for multi-rate transmission

A method of reconfiguring a protocol used by an application program includes determining an optimal protocol used by the application program and an optimal value of an operating parameter of the optimal protocol based on requirement information of the application program and system information obtained from a protocol layer; and when a current protocol used by the application program is not the optimal protocol, reconfiguring the current protocol used by the application program to the optimal protocol using at least one component module missing from the current protocol used by the application program and at least component module of the current protocol used by the application program, and setting a value of the operating parameter of the optimal protocol to the optimal value of the operating parameter of the optimal protocol.

Method of and apparatus for reconfiguring protocol used by application program

A packet routing apparatus and method are provided. The packet routing apparatus may participate in a sensor network. In certain aspects the packet routing apparatus may snatch a request to send (RTS) signal that is transmitted from a first node to a second node in the sensor network and may intervene on the relay path of the snatched data packet. In certain aspects, the packet routing apparatus may sniff a data packet that is transmitted from a first node to a second node and may intervene on the relay path of the sniffed data packet.

Packet routing apparatus and method

Provided is a super frame that may be used to reconfigure a dynamic protocol to synchronize a sensor node with different protocols of a hub device. The super frame enables a hub device to provide a real-time quality of service (QoS) with respect to a plurality of sensor application programs.
