    摘要: Disclosed is a method and apparatus for collision avoidance in a sensor network. The method includes transmitting data by a transmitter; comparing, by the transmitter, a remaining time between the data transmission and a backoff period with a turnaround time taken for the transmitter to switch from a transmit (Tx) mode to a receive (Rx) mode; selectively transmitting, by the transmitter, a busy signal indicating that a channel is in use, according to the comparison result; and receiving, by the transmitter, an acknowledgement (ACK) signal from a receiver after the turnaround time has elapsed.

    摘要: A sensor node management system in a Radio Frequency Identification/Ubiquitous Sensing Network (RFID/USN) infrastructure is provided, in which a sensor node has a local ID in a sensor network, a gateway receives, from the sensor node, node information including the local ID and an ID of a home gateway to which the sensor node initially belongs and registers the node information about the sensor node to a location information server, and the location information server registers and manages node information about sensor nodes within an area of the gateway. The location information server generates a global ID using the local ID and the ID of the home gateway, the global ID being recognized as an address of the sensor node by an Internet Protocol (IP) network.
