환경 모니터링 시스템에 적합한 최적 전송 전력 제어 및 선택 방법

In this paper, we propose a novel transmission power selection method based on transmission power control(TPC) algorithm for environment monitoring systems. Unlike previous TPC algorithms, which do not consider various wireless channel characteristic, the proposed method is based on selecting optimal transmission power of each node obtained by log-distance path loss model. It has fast and robust response in long distance communication which has path loss dispersion. The experimental result shows that the proposed method outperforms the previous algorithm in terms of the packet reception ratio (PRR) performance in various wireless channel environment.
