Abstract:
The present invention relates to a face detection system for a vehicle. At least one first lighting unit is configured to radiate infrared light onto a left side of a driver's face. At least one second lighting unit is configured to radiate infrared light onto a right side of the driver's face. An image capturing unit separately captures the driver's face onto which the infrared light is radiated from the first and second lighting units. A control unit acquires left and right images of the face from the image capturing unit, and obtains a difference image between the acquired left and right images, thus determining whether the driver is inattentive in looking ahead. The system stably performs the face detection function with no or less effect by external optical environments as well as reduced computational load.
Abstract:
The present invention provides a method, apparatus and article of manufacture for increasing network processing node interconnect capacity and reducing maximum hop count in a scalable multidimensional ring network by creating additional rings. Initially a node identification algorithm is selected and an initial network processing node in the scalable multidimensional ring network is selected as a first node in a new ring. The node identification algorithm is applied to the selected node to calculate a subsequent node in the new ring. The calculated node is then made the selected node. The applying and selecting steps terminate when applying the node identification algorithm to the selected node results in the calculated subsequent node being equal to the initial node, thereby creating the new ring. A new initial node is then selected and the new ring creation process continues. When a new initial node is selected that is already a member of a new ring the entire process terminates, thereby creating all the new rings in the new scalable multidimensional ring network.
Abstract:
A communication system having a source node, at least one mobile node, and a router that transmits data packets transmitted from the source node to a corresponding one of the at least one mobile node and multiplexes response signals to the data packets received from the corresponding one of the at least one mobile node to transmit the multiplexed response signals to the source node. The communication system includes: a link monitoring unit which calculates a capacity of a wireless link between the router and the corresponding one of the at least one mobile node; and a congestion control and adjustment unit which adjusts window field values in the response signals according to the calculated capacity. The router transmits the response signals, the response signals including the adjusted window field values to the source node, and the source node sequentially transmits the data packets on the basis of the adjusted window field values.
Abstract:
A method of implementing a Content-Centric Network (CCN) using an Internet Protocol (IP)-based network, and a gateway that may implement such a method, are provided. A method of implementing a CCN using an IP-based network may involve: determining an application protocol and a packet type corresponding to the application protocol of an IP-based network, the application protocol being included in an IP packet of an IP-based network, and generating a content name corresponding to the IP packet, based on the application protocol and the packet type.
Abstract:
A method and apparatus for controlling operation of a reception node in a content centric network (CCN) and for content included in the reception node using an operation identifier (OID) are provided. The OID may designate at least one control operation to be performed by the reception node.
Abstract:
Provided are communication devices and methods for requesting content in a network based on a hierarchical name structure. A content requester may search for content without the use of the entire content name in the network based on the hierarchical name structure.
Abstract:
A communication apparatus and method of a content router control a traffic transmission rate in a content-centric network (CCN), and the content router. In the communication method and the content router, a congestion of a network may be predicted, a warning signal indicating the congestion may be added to an interest packet, and the interest packet with the warning signal may be transmitted. Additionally, a traffic transmission rate may be controlled by adjusting a data packet transmission time based on a value of a marked field of a PIT. The PIT is set by receiving an interest packet to which a warning signal is added. Thus, the communication apparatus and method thereof provide reachability, while maintaining stability of network routing.
Abstract:
A Content-Centric Network and a method of performing routing between domains therefor are provided. The method includes identifying a route from an anchor hub in a first domain to one or more hubs in the first domain, the anchor hub being configured to store routing information between a first border hub of the hubs in the first domain and a second border hub in a second domain, detecting, by each of the hubs in the first domain, a neighboring hub based on a sync direction corresponding to the identified route, and sharing the routing information with the neighboring hub, the sharing of the routing information including performing a sync operation between the neighboring hub and each of the hubs in the first domain.

Provided is a scheme of transmitting sequential content (or data) in a content centric network (CCN). The scheme includes a push scheme which may reduce a load on a network and inefficiency of a transmission that results from a constant transmission of a content request message between devices.
