Abstract

In this paper, we efficiently simulated for collecting the data from the fixed sensor and mobile sensor of patients using the LEACH-Mobile method. The LEACH-Mobile method is the protocol to increase the mobility by adding the mobile node to the existed LEACH(:Low Energy Adaptive Clustering Hierarchy) protocol. It improves the mobility of The LEACH-Mobile in the LEACH, however it consumes more energy than the existed LEACH. There is reason why we use the LEACH-Mobile that the monitoring system is generally done by the CCTV and an periodic checkup by nurses. However the number of nurse is a few in the most of hospital. It can happen the accidents of the patients in out of the CCTV when the nurse can not see the monitoring system in the hospital. Therefore it is simulated to continuously gather the data of the position and sensors in the five situation of moving the patients in the hospital, it gets the result that the management of the mobile patients is more efficient.

본 논문은 LEACH-Mobile를 사용하여 병원에서 환자들의 위치와 센서 데이터의 지속적인 수집을 시뮬레이션 하고자 한다. LEACH-Mobile(: Low Energy Adaptive Clustering Hierarchy)은 기존의 LEACH프로토콜에서 mobile노드를 추가하여 이동성을 향상시킨 프로토콜이다. LEACH-Mobile은 LEACH에서 이동성이 개선되었지만, 기존 LEACH보다 소모되는 에너지의 양이 더 많다. 여기서 LEACH-Mobile을 사용하는 이유는 병원의 모니터링시스템은 대체적으로 cctv나 간호사들의 주기적인 확인으로 이루어진다. 하지만 대부분의 병원은 환자수에 비해 간호사의 수가 적다. 그렇기에 간호사가 보지 못한 사이에, cctv의 사각에서 일어나는 사고에 환자가 다칠 가능성이 있다. 그래서 위치와 센서 데이터를 5개의 상황으로 지속적으로 수집하는 시뮬레이션을 하였고, 그 결과는 병원에서의 환자들의 동선 관리를 보다 효율적으로 하였다.
