Abstract: A network management apparatus and method for remotely controlling a state of an IT device in order to use WOL to change a remote device from an inactive state to an active state over an IP network. The network management apparatus includes a detection pattern generator, a remote state controller, and a wake-up cause analyzer. By activating an inactivated PC connected over an IP network and positioned at a remote site using WOL to control a state of another IT device interoperating through the IP network as well as a state of the PC, it is possible to inactivate the device without unnecessarily having to leave the device on and then control the device as necessary, thereby reducing power consumption of the device and extending a lifetime of the device.

Abstract: A dynamic packet relay method of a personal area network (PAN) coordinator in a sensor network includes receiving a Child_Register message that includes information about a device associated with a coordinator and building or updating a network hierarchical structure; monitoring reception of a packet or a beacon from the coordinator and determining whether the coordinator is defective or not; and in response to a determination that the coordinator is defective, changing the current coordinator to one of devices belonging to a PAN as a new coordinator.
