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...

متن کاملSIR-Based Transmit Power Control Using CCI Table for Interference-Aware Channel Segregation Based Dynamic Channel Assignment
In wireless networks, the co-channel interference (CCI) limits the transmission quality since the same channel must be reused by spatially separated access points (APs) or base stations (BSs). Therefore, the channels must be reused so as to minimize the CCIs received at all APs or BSs. Recently, we proposed an interference-aware channel segregation based dynamic channel assignment (IACS-DCA) an...

متن کاملA Study of Interference-Aware Channel Segregation for HetNet Using Time-Division Channels
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...
