摘要
民用无线网络以及航空无线网络等未来无线网络需要承载需求多样化的业务类型和信息交互。数据包尺寸特征和数据包到达间隔等不同业务特征,对无线网络有至关重要的意义。然而,当前无线网络业务建模研究鲜有同时建模业务特征和业务特征的时间相关性,这导致对业务的建模刻画不够准确。本文提出一种联合业务特征概率分布和时间相关性的无线网络业务建模方法,保障了业务特征的概率分布和业务特征的时间相关性。本方法具有一般性,可以应用于民用无线网络的业务建模,也可以应用到航空无线领域,有利于对业务特性的把握,从而进行更加优化和确定性的资源分配。
Future wireless network such as civil wireless network and aviation wireless network needs to support increasingly diverse traffic types and Information Interaction demands.The different service characteristics including packet size characteristics and packet arrival interval characteristics are of crucial importance for wireless network.However,existing researches on wireless network traffic modeling rarely models both service features and their time correlation,which leads to inaccurate service models.A joint features probability distribution and time correlation method is proposed based on service modeling method for wireless network,ensuring the probability distribution and time correlation of service features.The proposed method is general and can be applied not only to the service modeling of civil wireless network,but also to the field of aviation wireless,which is conducive to achieving the service characteristics and conducting more optimized and deterministic resource allocation.
