Abstract:
본 발명은 데이터 중심 저장 센서 네트워크에서의 부하 감쇄 기술에 관한 것으로, GPSR(Greedy Perimeter Stateless Routing)는 센서들이 환경에서 발생한 이벤트들을 센서 네트워크 내에 저장하고 이벤트 정보가 필요한 내부 노드가 네트워크에 질의하여 이벤트 정보를 얻는 데이터 센트릭 스토리지(Date-Centric Storage) 센서 네트워크를 설계하는데 효율적인 지리적 위치 기반 라우팅 기술로서 활용된다. 하지만 GPSR은 패킷을 목적지로 전송할 때 목적지 주변을 돌며 순회하는 패킷 전달 경로(패리미터 워크)를 보이는데, 이는 DCS의 전체 네트워크 부하의 많은 부분을 차지한다. 이에 패리미터 워크를 제거하기 위한 효율적인 프루닝(pruning) 기법으로서, 그리드 전달 방식으로 전달이 불가능한 노드에 도달 했을 때, 현재 노드와 이웃 노드 중에 목적지에 가장 가까운 노드를 이벤트의 랑데부 노드로 설정하는 것을 특징으로 한다.

Abstract:
본 발명은 구조적 P2P 네트워크를 위한 데이터 매핑 방법 및 장치에 관한 것으로, 산술 매핑 기법을 사용하여 사전적 순서를 파괴하지 않으므로 복잡한 쿼리를 지원할 수 있음은 물론이고, 심볼들의 출현 빈도 확률을 알고 있는 경우에는 데이터가 균등하지 않은 경우에도 데이터를 키로 균일하게 매핑하므로 별도의 로드밸런싱을 하지 않거나 그 오버헤드를 최소화 할 수 있는 이점이 있다.
Abstract:
PURPOSE: A method for reducing overhead in a data centric storage sensor network and a sensor node are provided to reduce a perimeter work by establishing most adjacent node as a rendezvous node of an event. CONSTITUTION: If a get or put request of an application unit(501) or a sensor unit is generated, an indexing unit(505) performs hashing of a key value. A location based routing unit(507) generates a packet for transmitting to a rendezvous node from a GPSR(Greedy Perimeter Stateless Routing) or a GOAFR+(Greedy Routing And Face Routing+). The location based routing unit transmits the packet to an MAC protocol unit(509). A parameter work control unit(508) prevents a perimeter work about a packet which is arrived to an adjacent node around the destination of the packet.

PURPOSE: A method for preparing bis(2-hydroxyethyl)terephthalate is provided to enable the mass production of bis(2-hydroxyethyl)terephthalate as a polyester raw material from waste poly(ethyleneterephthalate). CONSTITUTION: A method for preparing bis(2-hydroxyethyl)terephthalate from waste poly(ethyleneterephthalate) comprises the steps of: pulverizing waste poly(ethyleneterephthalate); adding ethylene glycol; reacting them in a supercritical condition for 20-45 minutes to obtain solid bis(2-hydroxyethyl)terephthalate. The pulverization is carried out to obtain powder with a diameter of 10 mm or less using dry ice.
