Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
