分散式佇列隨機存取為依存取機制能在LTE行動網路有效處理巨量碰撞並支援機器間通訊。分散式佇列隨機存取能有效降低碰撞情形的代價是利用將存取延遲增加。而要能支援所有競爭機器設備，有必要確保行動網路的延遲範圍。因此最大存取延遲為一重要的效能指標。本篇論文提出針對多通道時槽阿囉哈系統最大存取延遲的分析模型。提出之分析模型可以用於基於分散式佇列存取支援機器間通訊之LTE網路群呼機制效能分析。分析結果顯示分析模型能準確分析模擬結果。
Distributed queueing (DQ)-based random access (RA) is an access protocol which can efficiently deal with the massive collision to support machine type communication in LTE cellular network. In DQ-based RA, there is a trade-off between the reduced collision and the increased access delay. To analyze the worst delay condition, it is necessary for the cellular network to guarantee the access delay bound. Thus, the maximum access delay is one important performance index in DQ-based RA. This thesis develops an analytical model to estimate the maximum access delay for DQ-based RA in a finite-users multi-channel slotted ALOHA system. The proposed model can be used to evaluate the performance of group paging using DQ-based RA for machine-type communication (MTC) in LTE. Numerical results show that the proposed models can accurately analyze the simulation results.
