Abstract

The maintenance of sensor networks, installed in a wide area has been an issue for a long time. In order to solve this problem, studies to supply energy to a sensor network using a robot has been carried out by several researchers. In this study, for a sensor network consisting of power nodes supplied with energy by multiple robots and sensor nodes around them, we propose a method of allocating a work area using a modified k-means algorithm so that the robots move the minimum distance. Through the simulation study using the energy transfer rate of the robot as a variable, it is shown that nodes of each allocated area can maintain survival, and the validity of the proposed modified k-means algorithm is verified.

넓은 지역에 설치되는 센서 네트워크 시스템은 유지 관리가 문제가 되어 왔으며, 이를 해결하기 위해 로봇을 사용하여 센서 네트워크에 에너지를 공급하려는 연구가 여러 연구자에 의해 수행되었다. 이 연구에서는 전력을 공급하는 노드들과 그 주변의 센서 노드들로 이루어진 센서 네트워크에 여러 대의 로봇을 사용하여 에너지를 공급하는 문제에서, 로봇이 최소 거리를 이동하도록 수정된 k-means 알고리즘을 사용하여 각 로봇이 작업할 영역을 분할하는 방법을 제안한다. 로봇의 에너지 전달률을 변수로 한 시뮬레이션 실험을 통해 분할된 각 영역의 센서 노드들이 동작을 유지할 수 있음을 보임으로써 제안한 수정 k-means 알고리즘의 타당성을 검증한다.
