Abstract

マルチメディア通信を目的としたCDMA分散ローカルエリアネットワークにおいて,同時送信局数の監視と2段階のチャネルアクセス優先プライオリティの導入により,等時性の必要な局に優先的に回線を留保するモデルのトラフィック解析を行なう.解析手法は山里ら[SST94-98]の固定長パケットSpread Unslotted Aloha方式をプライオリティの異なる2種類の呼に拡張したものである.解析の結果から,呼の種類毎に同時送信局数のしきい値を設定することにより,スループット特性及び遅延特性を制御できることを示す.

In this paper, the traffic properties in a spread unslotted ALOHA system with a fixed packet length embedded with the trunk reservation method is analyzed for multimedia communications in a CDMA distributed local area network environment. The analyzed system model employs a protocol with a monitoring function of the number of simultaneous users and two level transmission priorities. We extend the analysis method for a spread unslotted ALOHA system with a fixed packet length proposed by Yamazato et al. [SST94-98] in the model existing two different priorities' users. The analyzed results shows that we can control the throughput and delay performance by setting the proper threshold values of simultaneous users according to their respective priorities.
