A wireless multi-hop virtual cellular network (VCN) was recently proposed to avoid the large peak transmit power, resulting from the high transmission rates expected for future mobile communication systems. In VCN, calls hop through several links to reach the central port, which is the gateway to the network. With the use of a routing algorithm based on the(More)
In order to avoid the large peak transmit power, resulting from the high transmission rates expected for future mobile communication systems, a wireless multi-hop virtual cellular network (VCN) was recently proposed. In VCN, the transmitted signal from a mobile terminal is relayed via multi-hop links to the central port, which is the gateway to the core(More)
あらまし 次世代移動通信システムの実現に向けてバーチャルセルラネットワーク(VCN)が提案されている.送信電力の制 限された環境下において伝送速度が高速化した場合,従来のセルラネットワーク(CN)では通信可能なエリアが狭まり,セル端付 近の移動局は通信できず,呼損となってしまう.VCN ではマルチホップ通信の適用により送信電力を増大させることなく,通 信エリアを拡大できる.そのため,送信電力が制限された環境下において従来のシングルホップ CN に比べ,呼損率を改善する ことが可能である.本論文では,2ホップ VCN について計算機シミュレーションにより呼損率を求め,その導入効果を明らか にしている.また,VCN に maxSINR(More)
A multi-hop virtual cellular network (VCN) was proposed for future mobile communication systems. In VCN, the transmitted signal from a mobile terminal is relayed via multi-hop links to the central port, which is the gateway to the core network. In the original multi-hop VCN, a call is blocked when there is no channel available at one link over the multi-hop(More)
A wireless multi-hop virtual cellular network (VCN) was recently proposed to avoid the large peak transmit power, resulting from the high speed data transmissions expected in next generation mobile communication systems. In a multi-hop VCN, a central port (CP) which is a gateway to the core network, communicates with a mobile terminal (MT) via wireless(More)
