Abstract: A media access control device of a medium access control method in a sensor network reducing delay generated between a hop and a sensor node are provided to process data quickly by using a check interval of short length. A first node performs an LPL(Low Power Listening) which is the check interval which is most short among the usable check interval(S510). A first node receiving the downward traffic information determines the check interval by summing the traffic volume which periodically reports to the sink node by summing upward traffic and downward traffic which receives from its own lower nodes(S525). The first node transmits the upward traffic binding update message by using the long preamble of the type '2 fitted to the check interval of the node having the most small traffic(S540).

Abstract: Provided is a method of transmitting/receiving data in a sensor node for reducing overhearing of sensor nodes, and a sensor network which implements the method. A sender node having transmission data from among a plurality of nodes which perform a low power listening (LPL) operation in an asynchronous manner at predetermined time intervals, generates a long preamble including short preambles, each having information including a destination address of the transmission data, a remainder of the long preamble, and a length of the transmission data, and sequentially transmits the second preamble and the transmission data. A receiver node from among the plurality of nodes determines whether a valid signal is sensed during an active state in the LPL operation. If it is determined that the valid signal is sensed, the receiver node receives the short preamble transmitted from the sender node. The receiver node determines a duration time of a deactivated state of the receiver node based on the received first preamble, thereby reducing overhearing in the sensor network.

Abstract: A method for supplying an end-to-end QoS(Quality of Service) data transmission path and a device therefor are provided to enable data transmission through an end-to-end QoS path, and to be applied to all routers which ensure end-to-end QoS regardless of a type of QoS routing algorithm. An ingress node within a transmission network calculates a QoS path corresponding to a QoS parameter, and generates a VLAN(Virtual Local Area Network) ID(100). The calculated QoS path is mapped with a VLAN(110). The ingress node searches the VLAN ID according to information which distinguishes an inputted path corresponding to data inputted from a subscriber(120). An egress node within the transmission network reads the VLAN ID, and searches a correspondent destination address to send data to the destination(130).

Abstract: PURPOSE: A multicast service method in an MPLS(Multi Protocol Label Switching) network is provided to eliminate the consumption of resources due to path establishment by making all groups share a previously established LSP(Label Switched Path), instead of forming a distribution tree for each group. CONSTITUTION: A BSR(BootStrap Router), the highest priority node among RP(Rendezvous Point) nodes, broadcasts an integrated, certified bootstrap message to the RP nodes periodically, and the RP nodes broadcast bootstrap messages to their respective LERs(Label Edge Routers)(101). Subscriber terminals transfer join messages to RP nodes through LERs respectively. The LERs and the RP nodes get to a group data forwarding state and a multicast forwarding state respectively by the transmitted join messages(102). If a packet is received from an arbitrary subscriber terminal to an adjacent LER(103), the LER analyzes the header of the received IP packet(104). Based on RP information delivered from the bootstrap message, the LER transfers the packet to an RP node appointed to service a group specified as the destination of the packet(105). The RP node reproduces the transferred multicast data packet as much as the number of LERs to which the members of the group are connected and delivers them to the LERs through an LSP(106). Each LER reproduces the delivered packet as much as the number of group members in an external network and delivers them to the subscriber terminals(107).
Abstract translation: 目的：提供MPLS（Multi Protocol Label Switching，多协议标签交换）网络中的组播服务方式，通过使所有组共享先前建立的LSP（Label Switched Path，标签交换路径）来消除路由建立造成的资源消耗，而不是形成分布树 每组。 规定：RP（Rendezvous Point）节点中最高优先级节点的BSR（BootStrap Router）周期性地向RP节点广播一个综合认证的引导消息，RP节点将自举消息广播到其各自的LER（Label Edge Routers） （101）。 用户终端分别通过LER将消息传递到RP节点。 LER和RP节点分别通过发送的加入消息（102）获得组数据转发状态和组播转发状态。 如果从任意用户终端接收到分组到相邻的LER（103），则LER分析所接收的IP分组（104）的报头。 基于从引导消息传递的RP信息，LER将分组传送到被指定为服务于指定为分组的目的地的组（105）的RP节点。 RP节点再现传输的组播数据分组，与组中成员所连接的LER的数量一样多，并通过LSP将其传递给LER（106）。 每个LER将传送的分组与外部网络中的组成员的数量一样再现，并将它们传送到用户终端（107）。
