    摘要： An interband resonant tunneling intersubband transition laser is disclosed, and includes a semiconductor substrate, and a first cladding layer, an active region structure layer and a second cladding layer formed on the semiconductor substrate. The active region structure layer includes quantum well layers and quantum barrier layers that are alternately stacked and have a broken energy bandgap. Thus, the interband resonant tunneling intersubband transition laser operates in a cascade mode in which an intersubband radiative transition and interband tunneling of carriers consecutively and repetitively occur in the active region structure layer, and thus can achieve a high output from a simple, compact structure.

    摘要： A clustering method of a wireless sensor network is provided to minimize energy consumption. The clustering method includes the operations of determining a number of initial nodes within radio range of ordinary node, the ordinary nodes existing within radio range of a cluster head, and setting an ordinary node having a highest number of initial nodes among the ordinary nodes in the radio range of the cluster head, as a gateway. Because the number of usually large energy consuming cluster heads and gateways can be minimized, energy efficiency of wireless sensor network increases.

    摘要： A method and apparatus for managing a plurality of tuners for providing a broadcasting service to a plurality of devices in a home network. To provide the broadcast service requested by one of the devices, it is determined whether a tuner to which any broadcast service is pre-assigned can provide the requested broadcast service along with the pre-assigned broadcast service, and the requested broadcast service is additionally assigned to the tuner. If the tuner does not exist, a tuner to which no broadcast service is assigned is detected among from the tuners that can receive a broadcast program corresponding to the requested broadcast service, and the requested broadcast service is assigned to the tuner. Accordingly, in the environment in which various broadcast services are provided to a plurality of devices through a single gateway in a network, the broadcast services can be provided to the devices.

    摘要： A media access control method of a wireless sensor network (WSN) is provided. The media access control method includes first sensor nodes, existing in a non-overlapping area where clusters do not overlap, media-accessing with a Time Division Multiple Access (TDMA) method and communicating with a Cluster head (CH) in a first section. Further, and the method includes second sensor nodes, existing in an overlapping area where the clusters overlap, media-accessing with a contention-based method and communicating with the CH in a second section. Because communication between nodes of the non-overlapping area where the clusters do not overlap, uses a reservation-based TDMA method, collision between nodes can be prevented, and because communication between nodes of the overlapping area where the clusters overlap, uses a contention-based CSMA/CA method, interference between neighboring clusters can be prevented.

    摘要： A method and an apparatus for transmitting additional information on digital broadcasting to an IPTV by using a home gateway are provided. The additional information on a digital broadcast program is received through an IP based home network, and a DVBSTP packet is created by using the received additional information, and the packet is transmitted to the home network. Accordingly, a user can immediately obtain various pieces of information on a current broadcast program or a next broadcast program, and thus scheduled recording can be accurately carried out by using information on a broadcast time of the broadcast program.
