Description
以下、図2ないし図8に基づき、本発明に係るネットワークにおいて伝送電力を最適化する方法を説明する。まず、本発明の第1実施態様によるネットワークの伝送電力最適化方法を図2に基づき説明する。
以下、図3に基づき本発明の第2実施態様によるネットワークのスレーブにおいて伝送電力最適化方法を説明する。
以下、図4ないし図6に基づき、本発明の第3実施態様によるネットワークのマスタとスレーブとの伝送電力最適化方法を説明する。
第1比較段階(S416)において第1スレーブから受信されたリンク品質情報(Link_Quality)が許容感度(Q)と等しい場合、現在伝送電力確認段階(S410)で確認された現在伝送電力を基準伝送電力と記録する第1伝送電力記録段階(S418)を行い、伝送電力最適化段階(S480)に進む。
第1比較段階(S416)において、第1スレーブから受信されたリンク品質情報(Link_Quality)が許容感度(Q)より小さい場合、マスタは第1スレーブへの伝送電力を一定量ほど増やしながら基準伝送電力(RP)を求める増加アダプテーション段階に進む。
第1比較段階(S416)において第1スレーブから受信されたリンク品質情報(Link_Quality)が許容感度(Q)より大きい場合、マスタは現在伝送電力(PP)を減らしながら基準伝送電力(RP)を求める減少アダプテーション段階(S430)を行う。
以下、図7に基づき本発明の第4実施態様によるネットワークの伝送電力最適化方法を説明する。
以下、図8に基づき本発明の第5実施態様によるマスタ離脱時ネットワークの伝送電力最適化方法を説明する。
