Abstract:
PURPOSE: A signal extracting device is provided to improve a CNR(Carrier-to Noise Ratio) by generating PRZ(Pseudo Return-to-Zero). CONSTITUTION: A clock extracting unit extracts a clock from an NRZ signal. Interval lattice is regularly arranged in parallel. A generating unit generates a clock signal by using an optical fiber ring laser which is locked with the interval lattice. The interval lattice is constructed as a cladding mode and a core mode. The interval lattice is used as an NRZ-to-PRZ converter.

PURPOSE: An adaptable relay communication method for an UWB(Ultra-WideBand) link is provided to improve QoS(Quality of Service) and reception rates by reserving relay resources according to a QoS standard. CONSTITUTION: When a MAS(Medium Access Slot) is able to reserve S-R and MAS R-T, a reservation host node transmits a relay acceptance reservation code for the MAS R-T to a reservation target node, a relay request reservation reason code to a relay node, and a relay notification reservation reason code to the reservation target node. When the relay acceptance reservation code is received from the relay node and the reservation target node, the reservation host node transmits data through the relay node.

Abstract:
PURPOSE: A query processing system for supporting variable packet transmission in a wireless sensor network is provided to minimize energy consumption in a sensor node by controlling packets of a transmission message according to an attribute of the packets. CONSTITUTION: A sensor node(300) receives a query message from a base node. The sensor node collects environment data according to a query received in the query message. The sensor node generates a response message including the environment data. The sensor node generates the response message by changing a payload size of the response message packet according to attribute information included in the query message. The sensor node transmits the generated response message to the base node.

PURPOSE: A sensor network power saving method is provided to improve energy efficiency in a sensor network by managing data packets of a sensor node. CONSTITUTION: When a sensing time is arrived based on a sensing period, a peripheral environment is sensed. When a receiving time is arrived based on a receiving period, an RF(Radio Frequency) device is turned on and receives a state report packet from a child node. The RF device is turned off. When a transmission time is arrived according to a transmission period, the RF device is turned on and transmits sensing information for the peripheral environment to the state report packet of the child node. The RF device is turned off.
Abstract:
PURPOSE: A packet forwarding priority guarantee plan for improving a TCP(Transmission Control Protocol) in a mobile IP(Internet Protocol) packet buffering method is provided to guarantee a packet forwarding priority in a RED(Random Early Detection) buffer management method of a congested base station. CONSTITUTION: When packets of a portable terminal are moved to a network of a congested base station by using a smooth handoff method combined with a base station packet buffering method, the stored packets are displayed as priority packets. The priority packets are excluded from discarded targets in a RED buffer management method of the crowded base station. Loss packets are stored in a previous base station. The TCP performance of the portable terminal is improved in a mobile IP packet buffering method for marine telematics including a packet buffering method.
Abstract:
PURPOSE: A ship sensor network and an effective data merging method are provided to increase the lifetime of a network by reducing the amount of data transmission. CONSTITUTION: A plurality of sensor nodes(1-3) compares a collected average value of a data value with a current data value which is periodically collected. The plurality of the sensor nodes transmits the current data to a cluster head(10) when the current data value is over the average value. The cluster head transmits an average value of a data value transmitted from a plurality of the sensor nodes to a synchronization node(20). The synchronization node transmits the average value transmitted from the cluster head to an upper analysis system.
