A liveness check in a machine-to-machine (M2M) system is provided. A method for operating an M2M device includes generating a resource including information on a liveness check for a local device and confirming whether a probe signal for the liveness check is received from the local device. The liveness status of the local device is determined based on whether the probe signal is received.

Method and apparatus for checking liveness in machine to machine system

A method for performing resource offloading in an M2M system is provided. The method is performed based on an offloaded resource and offloaded attributes. The method includes generating an offloading request message that requests offloading of a source resource. In response to the offloading request message, offloading the source resource for which the offloading is requested. An offloaded resource is then generated using the offloaded source resource. Herein, the offloaded resource includes synchronization modes designating synchronization methods with the offloaded source resource as offloaded attributes.

Method and apparatus for managing resources and performing resource offloading in M2M system

A cooperative adaptive cruise control (CACC) system acquires a driving pattern of a target vehicle and variably provides an inter-vehicle distance and a responsible speed level of a subject vehicle that are followed by the CACC system based on the driving pattern. The CACC system includes a communication unit receiving vehicle information and road information of a region in which the subject vehicle travels; an information collection unit collecting driving information of a forward vehicle, vehicle information of the subject vehicle, and the road information; and a control unit controlling the inter-vehicle distance and the responsible speed level of the CACC system based on the driving pattern of the target vehicle according to generated control information.
