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 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.

Apparatus and method for sharing energy in wireless device

Provided is a communication system using a space division multi-user multiple input multiple output (SD-MIMO) communication method. A transmission apparatus may transmit, to each of terminals included within a coverage, common control information commonly transmitted to the terminals and individual control information individually transmitted to each of the terminals. The transmission apparatus does not precode the common control information and transmits the non-precoded common control information. The transmission apparatus precodes the individual control information and transmits the precoded individual control information.

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 data transmission system of providing preambles of different classes according to a characteristic of a terminal. A terminal having constraints on using a power with respect to a data reception may receive only a preamble of a particular class and thus decrease a power consumption. A general terminal may receive preambles of plural classes and quickly receive data.

Apparatuses and methods for data transmission and reception

Provided is an apparatus for adaptively operating an application program that may control whether to activate the application program based on whether a status of at least one of a wireless channel and a battery satisfy requirements of the application program.

Apparatus and method for adaptively operating an application program

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.

A medium access control (MAC) technique of a multihop sensor network. In the multihop sensor network, the MAC technique may contribute to significantly reducing transmission delay, and allow real-time services to be provided to all nodes by extending a guaranteed time slot (GTS) restricted to one hop in a personal area network (PAN) coordinator (PNC) to all nodes. Furthermore, the MAC technique may allow the number of available GTSs to be significantly increased, by using all 16 frequency band channels instead of using only a single frequency band and setting a multi-superframe.
