摘要： The present invention provides a method and apparatus for assigning a channel in an ad-hoc network, which can minimize beacon collision in the ad-hoc network and prevent channel overlapping or collision, and thus a channel can be efficiently assigned. The method of assigning a channel including: obtaining join order information which is information on the order in which a first node has been joined to a second node, which is a parent node, and level information of the second node in an ad-hoc network; determining a reference value for setting a channel that is to be assigned to the first node based on an address value of the first node, which is determined based on the join order information and the level information, a level value of the first node, a channel value of the second node, which is determined based on the level information, and the join order information; and determining a channel value of the first node by dividing the reference value by the maximum number of usable channels in the ad-hoc network.

摘要： Provided are a device of a node and method for beacon scheduling in an ad-hoc network and a data transmitting method thereof, which reduce power consumptions of nodes in an ad-hoc network when data communications between the nodes occur frequently. A beacon transmitting node checks its residual power. If the residual power is lower than a predetermined level, the beacon transmitting node notifies a plan to change its beacon cycle to other nodes. Thereafter, the beacon transmitting node increases the beacon cycle and transmits a beacon at the increased beacon cycles. Consequently, the beacon transmitting node can change its beacon cycle dynamically according to its power condition. Thus, the life span of the node can be increased. Therefore, it is possible to reduce an overhead of reconstructing a sensor network.

摘要： A method and an apparatus for assigning a time slot for transmitting a beacon in a wireless sensor network operated in a beacon mode are provided. In the method and apparatus for assigning a time slot according to the present invention, the total time slots assigned to the network are divided into N blocks and a node to which a time slot is exclusively assigned, among nodes to which a specific node is capable of directly and wirelessly transmitting, is selected as a parent node, the network is divided into two or more regions centering the parent node, a block having the time slot assigned to the parent node and adjacent blocks, among the N blocks, are respectively assigned to the regions, a time slot having been yet unassigned, among the time slots belonging to the block assigned to the region to which the specific node belongs among the divided regions, is assigned as the time slot of the specific node.

摘要： Disclosed is a finger guard. In an example embodiment, the finger guard includes a rectangular reticulate or netlike pad networked in a movable manner such that a plurality of unit plate pieces are connected to one another in four directions by a plurality of connecting loop members, and at least a pair of fastening belt members provided to extend or protrude parallel with one side of the reticulate pad, wherein the finger guard is configured to be worn in the form of a protective armor such that the reticulate pad covers and wraps around the dorsal side of a finger, upon which the finger guard is to be worn, and the respective fastening belt members pass the volar side of the finger to then be connected to be hooked on to one of the unit plate pieces in a state in which a portion of the volar side of the finger is opened and exposed in a length direction of the finger. With this configuration, the finger guard of the present disclosure is configured to be worn in the form of a protective armor such that fastening of the finger guard can be appropriately adjusted so as to be tailored to the thickness of a wearer's finger when the finger guard is worn for finger protection, thereby achieving enhanced functionality and quality for efficiently performing an elaborate and precise work by improving convenience in use and wearing comfort.
