In this paper, we create the network, node and process model using opnet software to simulate throughput performance of aos packet service, and choose various combinations of source packet length, transfer frame length and channel error rate to form different simulation scenarios. by analyzing the throughput - packet length, throughput - frame length simulation curves at different channel ber we get the optimal packet length and frame length configurations, and give some advice for the optimization of protocol configuration parameters according to throughput performance metric ; the complete node and process model of aos protocol have been built by opnet software, and a simple network scenario has been built to simulate and verify the validation of the protocol model
本文在建模模擬方面，用opnet軟體建立模擬aos協議包業務吞吐量性能的網路、節點、進程模型，選取不同的包長、幀長與通道誤比特率組合建立模擬場景進行模擬，得到不同誤比特率條件下吞吐量-包長、吞吐量-幀長關系曲線，經過分析得出最大吞吐量對應的最佳幀長、包長配置，給出以吞吐量性能為指標優化協議配置參數的建議;用opnet軟體搭建aos協議封裝節點模型和各個進程模型，建立簡單網路場景進行模擬驗證協議封裝節點模型的有效性。 -
Experiments show the presented hierarchical indexing scheme outperforms the original vq - based indexing method and probabilistic approximate nn searches. both presented approaches support quadratic - form distance metric and can integrate with relevance feedback techniques for practical large - scale image retrieval systems
