Abstract

In this paper, we propose an optimal placement of sensor nodes with 2.4GHz wireless channel characteristics. The proposed method determines optimal transmission range based on log-normal path loss model, and optimal number of sensor nodes calculating the density of sensor nodes. For the lossless data transmission, we search the optimal locations with self-organizing feature maps(SOM) using transmission range, and number of sensor nodes. We demonstrate that optimal transmission range is 20m, and optimal number of sensor nodes is 8. We performed simulations on the searching for optimal locations and confirmed the link condition of sensor nodes.

본 논문은 2.4GHz 무선 채널 특성을 가진 센서 노드의 손실 없는 데이터 전송을 위한 최적의 배치 방법을 제안한다. 제안한 방식은 무선 환경에서 log-normal path loss 모델을 구성하여 최적의 송수신 거리를 결정하고, 센서 노드의 밀도 계산을 통해서 최적의 센서 노드 개수를 구한다. 데이터 손실이 없는 전송을 위해 송수신 가능 거리와 센서 노드의 개수를 이용하여 공간에 최적으로 배치할 수 있는 위치를 SOM(Self-Organizing Feature Maps)으로 탐색한다. 논문에서 실험한 건물에서는 센서노드의 송수신 거리는 20m이고, 최적의 센서 노드 개수는 8개가 되었으며, 시뮬레이션을 통해서 센서 노드의 최적의 위치 탐색과 센서 노드의 연결 상태를 확인하였다.
