Interference-Aware Channel Segregation Based Dynamic Channel Assignment for Wireless Networks
Recently, we proposed an interference-aware channel segregation based dynamic channel assignment (IACS-DCA). In IACS-DCA, each base station (BS) measures the instantaneous co-channel interference (CCI) power on each available channel, computes the moving average CCI power using past CCI measurement results, and selects the channel having the lowest moving average CCI power. In this way, the CCI...

2. IACS-DCAの動作 各 BS は全チャネルの平均 CCI 電力を記録した干渉テー ブルを持っている.各 BS は,周辺 BS が報知するビーコ ン信号を観測して全チャネルの瞬時 CCI 電力を測定し,平 均 CCI 電力を更新する.次に,平均 CCI 電力最小のチャネ ルを一つ選択して使用チャネルとし,ビーコン信号を送信 する.各 BS は,一定周期で上記の動作を繰り返す. 3. 計算機シミュレーション 計算機シミュレーション諸元を表 1 に示す.図 1 に示す ように C=8 個のチャネルを考える.HetNet の BS 配置の一 例を図 2 に示す.六角形の大セルの中央に MBS を一つ配 置し,NSBS=29 個の SBS を大セル内に配置する.各 BS(MBS と SBS)は,C=8 個のチャネルの中から平均 CCI 最 小のチャネルを使用チャネルとして選択する.平...
متن کاملImpact of Shadowing Correlation on Interference- Aware Channel Segregation Based DCA
In wireless networks, the same channel must be reused at different access points (APs). The co-channel interference (CCI) is a predominant factor that limits the transmission quality. Recently, we proposed an interferenceaware channel segregation based dynamic channel assignment (IACS-DCA) which forms a channel reuse pattern with low CCI in a distributed manner. In our proposed IACS-DCA, each A...
متن کامل[Poster Presentation]A Study on Adaptability of Interference-Aware Channel Segregation To Varying CCI Environment
By applying interference-aware channel segregation based dynamic channel assignment (IACS-DCA) algorithm, each access point (AP) can use a channel with low co-channel interference (CCI) in a distributed manner. Interference environment may vary due to e.g., switching on/off of APs. Its adaptability to varying CCI environment has been left as an interesting study. In this paper, we investigate t...
